All ball bearing units supplied by Climax are manufactured to tolerance class ABEC-1 per ANSI/ABMA Std 7, latest revision. Bearing tolerances are based on the nominal bore or inner diameter of the bearing. The following table lists tolerances for the bearing bore, bore runout, bearing width, and the diameter of the shaft on which the bearing will be mounted.
| Bore Diameter (in) | Bore Diameter Tolerance (in) | Bore Radial Runout Tolerance (in) | Width Tolerance (in) | Shaft Diameter Tolerance (in) |
|---|---|---|---|---|
| 1/2 | +0.0005 / +0.0010 | Max +0.0004 | +0.0000 / -0.0047 | +0.000 / -0.001 |
| 5/8 | +0.0005 / +0.0010 | Max +0.0004 | +0.0000 / -0.0047 | +0.000 / -0.001 |
