YR-3/4 ID. 1/4" OD. 3/4" Non sealed

The Yoke Type Track Roller is a non-separable bearing unit consisting of an outer ring, needle rollers, an inner ring, and two retaining washers securely fastened to the inner ring. It includes lubrication holes and a groove in the bore of the inner ring for easy re-lubrication. 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 clamping isn't possible, ensure a close axial fit in the yoke.
