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