YR, Smith Yoke Type Cam Followers - Made in USA

The yoke type track roller is a non-separable unit consisting of an outer ring, a full complement of needle rollers, an inner ring and two retaining washers securely fastened to the inner ring. Lubrication holes and a lubrication groove in the bore of the inner ring provide for re-lubrication when a cross-drilled bolt or shaft, which can be lubricated from the end, is used.
The track roller should be clamped endwise between parallel faces perpendicular to the axis to prevent the retaining washers from coming off under load. If the unit cannot be clamped, a close axial fit in the yoke is required.
