Ball Bearing Tolerances Explained - S Bearings, EZO

This tolerance ensures the bearing outer ring surface is close enough to a right angle with the outer ring face. Tolerance figures for face runout/OD are given for P5 and P4 precision grades. All points on one circle of the outer ring bore next to the face are measured during one revolution while the inner ring is stationary.

Ball Bearing Tolerances Explained - BEARING NEWS

Sep 29, 2020· Since the width is usually less critical, the tolerances are wider than for the bearing bore or OD. A width deviation of +0/- 120 means that if you measure the inner or outer ring width at any single point around, say, a 688 (4mm wide) bearing, it should not be wider than 4mm (the nominal dimension) or narrower than 3.880mm.

Ball bearing inner race tolerance zone - Practical Machinist

Mar 13, 2017· The choice of ID and OD ball bearing fits typically go in an inverse relationship: tight on shaft, use slip fit in housing. Making both fits tight can cause unwanted preload of the bearing if there are two opposing bearings in the assely. The speed at which the bearing rotates is also a factor, of course, and can influence the design of the fit.
