1. TEFLON® line the bearing bore or the pin or bolt O.D.
2. Dry film the bearing bore and/or the pin or bolt O.D.
3. Introduce lubrication holes and grooves in the pin or bolt or the ball members
Suggested pin materials are 17-4PH and PH13-8Mo stainless steel, and 4130/4340 steel chrome plated .002 thick. Pins, either bare or plated, should be heat treated to the required shear strength (108,000 psi Ref.) and ground and polished to the required dimensions with a surface finish of 8 R a or better. The recommended fit between the pin or bolt and the bearing bore is line-to-line to .001 loose.

(C) = M+[T - H + (2 X E )]
(Tolerance + .008/-.007)
T = average housing thickness
H = average outer race thickness
E = average V-groove depth in race, depending
on groove.
