    Sharpen your knowledge.  Improve product designs. This C-Flex training page goes hand in hand with knowledgeable engineers to delve into areas where help is needed. Send us your current design challenges and leave with a plan for making a difference in your product.  cflex@c-flex.com The following are four areas where you may be able to find a solution right on our website. JD302 How does the pivot work? There is an outer sleeve and an inner core.  The sleeves give the bearing a round exterior that can be mounted easily in a round hole. Since the sleeves do not affect the performance of the internal springs, it's possible to have many different sleeve combinations of the same bearing such as cantilever or double ended. This allows for a wide range of mounting options that all have the same performance characteristics. Conversely, It's possible to have the same sleeves with a wide variety of spring sizes inside to provide the desired performance characteristics. The inner core.  The core is the central element containing the springs which allow the bearing to rotate.   Click here for more information…. Laser marked logo What size should I select? C-Flex Bearing Company offers two types of pivot bearings in 10 sizes with 3 spring series for each size resulting in 60 different standard parts in addition to a large number of custom pivot bearings. Due to the fact that some of these bearings have overlapping properties it can be a confusing process to select the right pivot bearing.   Click here for more information…. RadialLoadingTension How are they installed? Clamp Screws:   Take care to not over-tighten the clamp and crush the sleeve. Epoxy:  If possible, inject the epoxy around the outside of the bearing after it has been positioned in the mounting hole. Make sure that no epoxy gets into the core or between the core and the sleeves of the bearing. Shrink Fit:   Cool the bearing to -100 °F using liquid nitrogen and heat the mounting hole. Quickly locate the bearing in mounting hole and hold in position until temperatures equalize and bearing is secured. Shrink fit is typically permanent and cannot be undone without damaging bearing.   Click here for more information…. image I don’t see the required specifications for my application? C-Flex Bearing Company can provide a vast array of custom alterations to the standard pivot bearings. If you have an application where a standard pivot bearing will not suffice then see if one of the alterations we offer below will suit your needs.

    The weather is beginning to look promising in upstate New York.  We are ready to greet warmer temperatures and sunshine with positive attitudes and plenty of energy.  Our manufacturing floor is busy with machines humming, our team working hard with efficiency and enthusiasm completing orders of standard and custom products.  A lot of energy within our walls lately!  Could it be because spring is in the air and daffodils are blooming …or maybe we are just a happy team of hard workers. DSC_6996 Speaking of energy, did you know that the C-Flex pivot eliminates energy loss due to friction?  The C-Flex pivot consists of two stainless steel sleeves held in position by three leaf springs on two planes.  There is no contact between the sleeves thus eliminating friction.  The springs provide the pivotal action which is self centering.  No lubrication nor maintenance required.  Inquire today! image If you don’t need a pivot but need to correct misalignments in your system, consider the C-Flex flexible coupling, also a huge energy reducer.   The use of the C-Flex coupling to connect rotating shafts will result in lower energy usage and bearing failure since less stress is placed upon those bearings.  Misalignment forces on the bearings of a rotating system generates heat resulting in wasted energy.  C-Flex couplings minimize these misalignment forces and result in a more energy efficient system.

    C-Flex is now in it's 23rd year of business and going strong. We are developing new products and customizing standard products for our customers. Among the many offerings are spring rates and diameters of extended length. These items, either cantilever or double end have an ?L? designation in their part number (e.g. D-20L10). ?L? indicated in increments of 0.010? how much longer (OAL) the pivot is than standard. To further explain, a D-20L10 would be 0.100? longer than the standard D-20 or 0.500? long, with the slot in the center as is normally provided. For double end versions, there is three, two digit suffixes which indicate: 1. the increase in overall length 2. the increase in length (if any) of the middle sleeve, and 3. the increase in length of the two outer sleeves. Here is another example: part number FD-10L20L10L05 indicates a FD-10 pivot bearing which includes an increase in overall length of 0.200? to a total OAL of 0.600?. The middle sleeve has been increased in length by 0.100? and each of the two outer sleeves have been increased by 0.050?. In the D size we offer the L version as a standard up to L40 (0.800? long) and the F Size OAL up to L60 (1.200? long). Additional sizes with varying torsional spring rates and load capacities may be available. C-Flex has manufactured many versions of our standard pivot bearing over the course of the companies 23 year history. Call us with your required torsional spring rate, load requirements, and any other specifications for your application. We might have a sample available for you to test. Listing of current designs available in 1/4? and 3/8?: image In addition to the above, we currently manufacture two large, non-standard pivot bearings. Part number J-40. Material is 400 series stainless steel. Diameter is 1?. Yield strength is 197 KSI. Ultimate tensile strength is 294 KSI. Fatigue strength is 75 KSI.

  • Loading Pivot Bearings with Locator Flats

    18 May 2016

    The locator flats are for use with a cup point or flat bottomed set screw so that when you tighten the set screw it will seat on the flat and align the bearing in the hole.  Locator flats make installation a little easier and prevent the bearing from rotating in its mounting hole compared to using a set screw alone.  They are especially useful for heavier pivots with high torsional spring rates. Flat's are generally used when bearing angle position is critical or high torques are being applied and there is a risk the bearing may slip in its mounting hole.  There is not enough material on the thin side to cut flats, they can only be on the thick side.  * Customer has the option of only one flat or two on a pivot. CANTILEVER Locator Flat Spec. image DOUBLE END Locator Flat Spec. image   Types of pivot loading: Compression and tension loading refer to the forces on the springs in the center of the bearing.  The springs are thin so if they are compressed they may buckle and fail at a lower load than if they were in tension.  Basically you want to rotate the bearing in its mounting hole so that the force on the front end of the bearing is on the thin side.  That being said the load capacity for an H-20 in compression is 221 pounds so if you are only applying 1 pound it won't make a difference what position you use.   In general, loading in tension is just a good habit to maintain. clip_image001 Press fit mounting should be avoided since the force required to insert the bearing is usually higher than the load capacity of the bearing and can damage it.  Using a set screw on the outside diameter or a clamp screw is sufficient for most applications, other methods are generally only used in high load applications.

    It has been busy times here at C-Flex these past two months.  The popularity of the C-Flex Coupling has exploded! exploded We even purchased a new HAAS MINI MILL to increase production.  Since this new addition, we are in desperate need of an experienced CNC Machinist to program, set up and run these machines. This will be C-Flex’ 3rd mini mill actively running on our shop floor.  EXCITING! Haas Questions Asked and Answered While working with our customers, getting their orders ready, a few questions regarding the coupling have come up which might not be answered with clarity on our website.   Let’s address these inquiries just in case anyone else has the same question/s. Question:  What is the temperature range of the C-Flex Lattice Coupling? Answer:   The couplings are the same material as our pivot bearings (400 series SS).  Reference FAQ (remove the word “bearing”).   The temperature range is –100 deg. F to 375 deg. F.   The coupling can be held up to 450 degrees for no more than 8 hours otherwise damage may occur. Question:  On the data sheet for the English C-Flex Lattice Servo Coupling, 301500 couplings have an “H” dimension of 0.505 which is smaller than the smaller coupling. Is this correct? Answer:  There is an error in our catalog as well as the CAD model.  All of the actual 1.25” diameter parts have an “H” dimension of 0.386 which is a logical value considering the size below and above it.  The value was changed however the models and catalogs did not get updated. Question:  What is the Moment of Inertia for the smallest bore size of the Lattice Couplings? Answer:  For the 50XXXX Lattice Coupling Coupling ID                 Bore (inches)             MOI(lbs*In^2) 500750                          0.125”                            0.0042 501000                          0.250”                            0.0138 501250                          0.375”                            0.0350 501500                          0.500”                            0.1012 501750                          0.625”                            0.2020 502000                          0.750”                            0.3728 502500                         0.875”                             0.9636 For the 30XXXX Lattice SERVO Coupling Coupling ID                 Bore (inches)             MOI(lbs*In^2) 300750                       0.0033”                            0.125 301000                      0.0145”                             0.250 301250                      0.0429”                             0.375 301500                      0.1091”                             0.500 301750                      0.2287”                             0.625 302000                      0.4444”                             0.750 302500                      1.3471”                             0.875   Question:   What IS the “H” Dimension? The H dimension is the length of engagement of hub onto the shaft.  The hub is internal to the flexures. A shaft can penetrate through the middle.   We continue to welcome more questions and comments so PLEASE give us a call. We’d love to talk to you about the C-Flex Flexible Coupling and the C-Flex Frictionless Bearing/Pivot.   315-895-7454 PHONE.

  • Maximum Rotation Angles of the C-Flex Pivot Bearing

    18 Aug 2015
    Joanne

    0
    image A question was asked by one of our customers concerning maximum rotation angles and hard stop limits.   The max rotation angles are limits set for recommended usage and not physical limits. For example, in regards to the 10 series pivot bearings, C-Flex recommends maximum rotation in one direction of 15 degrees for indefinite life and 30 degrees plus/minus rotation before damage occurs. The C-Flex pivot bearing, in the 10 series will rotate a minimum of 30 degrees each way with the actual hard stop occurring sometime after that, possibly at 35 degrees. This is similar to the 20 series which will rotate at least 15 degrees each way and the 30 series which will rotate at least 7 degrees each way. It is recommended that the user put stops in their application to prevent excessive rotation. If that is not possible, we will customize the pivot bearing with limit stops so the springs will not be damaged if the stop are hit with excessive force. Reference the life cycle charts below: Also found on our site under LIFE PROJECTIONS image image If using the solid models of the C-Flex pivot bearing, it will exceed recommended angles of rotation or rather, will reflect rotation to the hard stops. Solid models can be found at our site under ?What We Do? => ?Pivot Bearings? => ?Downloadable Solid Models?. Call us with any questions at 315-895-7454.

    Life Cycle Testing of C-Flex Products You will consider many products and many scenarios before putting your design ideas into production. At C-Flex, we understand the importance of supplying products that won't repeatedly break down before their time. C-Flex Bearing life cycle testing services enable you to project the longevity of our product in your design before failure. Life expectancy of the C-Flex pivot is a result of fatigue on spring materials resulting from repeated applied loads and angles of rotation. If used within rated values, the user can expect indefinite life from the C-Flex pivot bearing. If however, the application requires exceeding any recommended limit, a finite and predictable life may be calculated. The charts provided in our catalogue reflect life lines for usage under a full range of motion about center. If the application requires rotation to only one side, C-Flex will help calculate the expected longevity of use within the application. *An example is provided on page 6, section III of the Design Guide . C-Flex has the facilities and expertise to conduct accelerated life cycle testing on our pivots and coupling products. This type of test is conducted using aggressive condition specifications based upon customer requests. Testing Services Breakdown: Life Cycle Test for 1 to 4 units. Standard lead time is 2 - 3 weeks depending on requirements of test. 10 million cycles at a +/- 2.5 degree offset is considered a standard customer defined test. Room temperature for all levels of testing with cycle speed of 1400/min. Number of cycles 10. The customer may define angle of rotation , number of units tested, and may request extended life testing e.g. 30 million cycles.

This means best practices in the C-Flex production process.  Breaking down efficiency even further to examination at a micro level, we look at the marking technology utilized at C-Flex and the benefits transferred to the customer. Laser Marking:  A level in production which has saved final process time as well as increased customer satisfaction.   image It has been a few years since C-Flex Bearing Co., Inc. first introduced Laser Marking Technology via True Pulsed Fiber Laser into the final stage production process. The old system of etching onto the metal part required we purchase bottles of chemicals for the marking process.  The results were not crisp, clean, and were certainly not easily customized to customer part number identification. Laser marked logo The many benefits associated with laser marking,  using a table top marking system, has increased efficiency and satisfaction for customers. 1.  C-Flex can produce characters, logos, and bar codes with continuous lines to improve mark legibility. 2.  A wide variety of text styles improve image and the customer sense of quality for the final product. 3.  The laser mark is permanent on a variety of materials which prevents losing identifying information and is important to traceability. 4.  The cost for custom marking to our customers is minimized. 5.  The lack of chemicals and fluids creates a cleaner more sustainable environment. 6.  Greater uptime because less maintenance, quick operator set up and utilization   This is how it works:
    A. Turn on the laptop . B.  Set up mark on software. C.  Place component into the machine. D.  Adjust any settings/placement. E.  Close the door and mark.
    Not only is the resulting product marking for company identification, part number, and serial number traceability cleaner and cosmetically more pleasing to our customers, Laser marked part but it has reduced internal costs as well as increased production efficiency to the C-Flex manufacturing operations. As we continue to support ongoing manufacturing transformations for not only production efficiency but a more proficient organization, the satisfaction from long time customers goes hand in hand.  With efficiencies built into every process, C-Flex exists on a solid foundation yet remains flexible to capture new markets and drive customer loyalty.
