Yoke Type cam followers  are intended primarily for applications where loading conditions exceed the capabilities of stud type cam followers, orwhere clevis mounting is desired. Clevis mounting provides support on both sides of the cam follower and permits use of a high strength pin. Yoke type cam fol lowers are available with and without seals, and with crowned outer rings.

yoke rollers correspond in many respects to the same size cam follower, except they are mounted on a pin for use in yoke type applications for greater shock resistance.

Yoke rollers should be clamped axially or mounted within closely fitting side rails to prevent dis place ment of the end plates. For applications with heavy loads, it is recommended to heat treat the pin and use a press fit

for the inner ring. A soft pin and light press or push fit are sufficient for lightly loaded applications. When press fitting a yoke roller, pres sure should be applied centrally and uniformly against the end plate, never

against the outer ring.

The pin should have a suitable lead-in chamfer or radius to prevent scoring and to hold the mounting force to a minimum.
