XT Hubs & Bushings

XT® Hub & Bushings are a computer-designed hub and bushing specifically developed for conveyor pulley applications. This design utilizes a tapered bore bushing, providing all the holding power you’ll ever need for conveyor pulleys, while providing easier installation and removal than other bushing types

  • Designed for conveyor pulley applications
  • 2” per foot taper
  • Self-Seating – no need to hammer bushing in
  • Less axial movement – reduces end disc stress and seats quicker
  • High clamping force eliminates need for keyway on Non-Drives
  • Bolts equally space for even draw-up
  • More material in the barrel
  • Full length hub engagement
  • Flange deflection stores up capscrew torque for seating while running
  • Easy Removal
  • Full Size keys in max bores for size 50 and larger

Precision offers the XT®with larger hub diameters and longer hubs for greater load capacity. Precision has found that the XT®taper and heavy barrel are best suited to our design philosophy and recommends them for pulley hub usages.

   

QD Hubs & Bushings

  • Designed for a wide variety of applications
  • 3/4” per foot taper - self-seating
  • High clamping force eliminates need for keyway on non-drives
  • Flange deflection stores up capscrew torque for seating while running
