  • Sealed Spherical Roller Bearings - Bearing Supplies

    Radial play, or internal clearance, is the internal radial looseness in a bearing and is the measured value of the total radial movement of the outer ring with respect to the inner ring in a plane perpendicular to the bearing axis. Ball bearings are assembled to radial play values depending upon a desired range.

  • Radial Play - Bearing Internal Clearance | AST Bearings

    If movement is in the radial direction, it is called radial internal clearance; if in the axial direction, axial internal clearance. ( Fig. 10-1 ) Bearing performance depends greatly upon internal clearance during operation (also referred to as operating clearance); inappropriate clearance results in short rolling fatigue life and generation of heat, noise or vibration.
