what is acceptable tolerance for front wheel bearing / spindle fit? - Studebaker Drivers Club Forum

4/11/2017· Where the inner cone goes, the spindle dimension is 1.4990/1.4995" o.d. The cone bearing is type 2788, for which Timken shows the min. i.d. is 1.5000 and the max. i.d. is 1.5005. The cone mates with cup 2720, and both parts are still in common use in trailer hubs. This is a close sliding fit, does not need to be pressed on.
