To reduce friction and bearing pre-load this assembly uses an angular contact ball bearing in the rear and a heavy-duty Timken® tapered bearing in the front. Bearing pre-load can be reduced from 18-20 inch lbs. to 3-5 inch lbs. Sold pre-assembled and the bearing pre-load is factory set using a hardened solid pre-load spacer rather than a crush sleeve or shims. Field shimming for preload is not required. Also available with ceramic bearings.
