Ultramite Gear Drives

Falk Ultramite Parallel Shaft Drives are built for longer service life. An integral high-speed pinion is fully supported by bearings within the gearbox, not by motor bearings while dual lip seals prevent contamination. Ultramite is motor-independant allowing the use of standard NEMA C-face or IEC motors. With a lifetime removal guarantee, shaft mounts using our patented TA taper bushing are guaranteed to come off the shaft, regardless of length of service or operating conditions, or Rexnord will replace it for free.
