Clearance – Axial vs Radial Deflection

Bearing Internal Clearance Relationship

Radial and Axial Clearance share a relationship dependent on conformity and contact angle. This relationship will be constant within each raceway geometry offering for each series. Axial Clearances for C-Type bearings are much greater than that of a same-sized X-Type bearing.

See the graphs below which illustrate the relationship between radial and axial clearances by cross section. Please contact Silverthin Engineering for any needed calculations related to your application and design needs.

1 Angular contact bearings have this same relationship, but it is generally only a reference as performance of an angular contact bearing is driven by the desired contact angle.
