  • 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 ...
