» Bearings for high speed operations

Sep 15, 1994· Bearings with smaller and lighter rolling elements are today’s answer to the never-ending pursuit of higher spindle speeds, cooler running and even higher stiffness. These bearings are increasingly used in high performance CNC lathes, machining centres and high frequency internal grinding spindles.

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
