    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-(300-x-250) Spring into spring with our springs or couplings.  We have standard and custom products to fit your needs within your budget. Contact us!

    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. Rated rotational angle is +/- 2.5 degrees for infinite life at zero load. Rated max. operating load is 2100 lbs. both radial and axial. Rated stiffness is 175,000 lbs./inch (radial and axial). Part number K-30. Material is 400 series stainless steel. Dimensions are 1.25? dia. x 3.00? lg. Radial and Axial load capacity is 4500 lbs. Max. rotation for infinite life at zero load is +/- 2.6 degrees. Maximum rotation for infinite life with a 4500 lb. radial load is +/- 1.4 degrees. Torsional spring rate is 71.8 lb.-in/degree.

  • Loading Pivot Bearings with Locator Flats

    by Joanne

    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.
