  • Spindle Bearings | KRW Leipzig

    Spindle bearings are self-latching bearings that cannot be disassembled. In addition to radial forces, they can absorb single-sided axial forces as well as, in combination with a second mirror-image arranged angular spindle bearing, two-sided axial forces and radial forces. For combined bearing sets there is a distinction between O-, X-, or ...

  • Angular Contact (Spindle) bearings | Principle

    Angular contact (Spindle) bearings are designed to withstand axial loads in only one direction. The “V” laser marking on the outer ring denotes the direction of load applied to the bearing outer ring. Using the proper assembly tooling will prevent damage of the bearing. Duplex bearings labeled (DB), (DF), or (DT) are always packed in pairs ...

    2013-1-26 · In a conventional spindle bearing the rotation causes a centrifugal force F c on the balls and the inner ring which results in a radial expansion of the inner ring ( Updelta x_{rad} ) and a movement of the balls. This leads to changing contact angles resulting in an axial displacement of the inner ring ( Updelta x_{ax} ).The changed contact angles cause a decrease in axial stiffness [].
