APPENDIX RADIAL INTERNAL CLEARANCE FOR BALL BEARING UNITS Radial internal clearance provides for thermal expansion and slight misalignment of the inner and outer rings. Internal clearances for ball bearing units are typically greater than those of RADIAL INTERNAL CLEARANCE FOR CYLINDRICAL BORE BEARINGS Bore diameter CO C3 C4 TOLERANCES INNER RING BORE DIAMETER RING WIDTH TOLERANCES the same size of radial ball bearings. Proper internal clearance is important for optimal bearing life. Below are the most common clearance classifications for cylindrical bore insert bearings.
