Bearing Assembly Preload Information || Dynaroll

Preload is the force that is applied to a bearing assembly during installation to remove the axial play and to further compress the bearing to provide both axial and radial stiffness. It is an important design parameter, affecting rotational performance and lifetime of a bearing assembly. After preload, the resulting ball contact angle a must be considered.

Standard preload - Inner rings pressed together (maximum stiffness)

Outer rings pressed together (less stiffness)
