• Examples

    Example 1: Headstock with open housing

    The adjustable GLM radial plain bearings are mounted directly in the bores of the headstock. The axial guiding is placed between the GLM, adjusted for correct play and tightened with a Spieth Locknut against the spindle end. V-rings are used for sealing against oil loss.

    Example 2: Work piece spindle head with bearing flange sleeve and closed housing

    In this stable spindle head design, radial guidance is achieved using two GLM bearings mounted in the bearing flange sleeve.

    Axial guidance is provided by a spindle collar, which is located on the working side outside the GLM bearing.

    A Spieth clamping set is used to eliminate the assembly play between the housing borehole and bearing flange sleeve on the spindle drive side. V-rings are provided to prevent oil loss.

  • Benefits
