Y28 Track Runner Bearings, Yoke Type without Stud, Unsealed, 0.875" Outside Diameter, 0.2500" Inner Diameter

Description

This yoke style RBC needle bearing cam follower is traditional in design, with a heavy outer ring cross section and a full complement of needle rollers. It offers high dynamic and static load carrying capability, and anti-friction performance, in a compact design. Yoke rollers are mounted with a pin in a yoke. Under load the pin is subject to shear and bending stresses. RBC recommends that the yoke arms are located as close to the yoke roller as possible. In case of widely spaced pin supports, the resulting pin deflection may cause yoke roller damage. RBC 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 displacement 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, pressure 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. RBC Bearings has been providing bearing solutions to our customers since 1919.
