What is the required surface finish & lubricity for Keyless Locking Devices?

Climax Keyless Locking Devices carry rated capacities that rely upon both lubricity and surface finish. Components to be mounted should be machined to achieve a surface finish of between 63 and 125 ┬ÁIN RMS. A surface finish outside this range could result in a reduction of the load carrying capacity of the connection. Lubricity is likewise critically important to the successful application of our products, as it directly affects the Coefficient of Friction (COF) between mated components. Our internal locking assemblies are supplied and installed with ordinary machine oil on all locking screws and mated surfaces to achieve a COF equal to .12. Our external shrink discs and keyless rigid couplings require a solvent cleaned and dry shaft interface to achieve a COF equal to .15.
