Coupling News and CNC Milling

It has been busy times here at C-Flex these past two months.  The popularity of the C-Flex Coupling has 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!

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). 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?

Answer: 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 Pivot Bearing.

Going Green Technology Requirements:
Our pivots require no lubrication and contain no toxic materials resulting in zero environmental contamination.
