  • Slewing bearing clearance - XZWD

    The clearance of the slewing ring bearing is the maximum amount of movement in which one ferrule is fixed and the other rim is radially or axially. The maximum amount of motion in the radial direction is called the radial clearance, and the maximum amount of motion in the axial direction is called the axial clearance.
