31320 X/DF

Matched tapered roller bearings arranged face-to-face
Matched tapered roller bearings arranged face-to-face (X-arrangement, load lines diverge towards the bearing axis) accommodate high radial loads and axial loads in both directions. The precision manufactured intermediate ring between the outer rings enables a defined internal clearance or preload to be achieved when mounted. Matched tapered roller bearings are typically used in gearboxes, hoisting equipment, rolling mills, and machines in the mining industry.

  • High radial load carrying capacity
  • Designed for axial loads in both directions
  • Relatively high stiffness
  • Surface finish on the contact surfaces of the rollers and raceways that enhances operational reliability
