    2021-1-1 · A tapered roller bearing is used between the eccentric shaft and the wave generator. Thus, the meshing side clearance can be eliminated via the axial preload of the reducer, thereby largely improving its operation accuracy. To reduce axial size of the reducer, only one tapered roller bearing is used in wave generator.

  • Radial Play - Bearing Internal Clearance | AST Bearings

    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. The radial play is determined by the actual raceway diameters and ball diameter.
