Tapered: Bearings that can support axial and radial forces. Due to a conical geometry that creates a linear contact, these bearings can carry greater loads than ball bearings, which have point contact. Tapered roller bearings can be separated into a cone assembly (inner ring, rollers, cage) and a cup (outer ring). These bearings can be used in industries such as agriculture, construction, mining, automotive, and robotics.


Product Features:

  • Material Technology - Hardened high carbon chromium steel
  • Advanced Materials - Patented materials including High TF and Super TF are available for more arduous conditions
  • Patented NSK HR taper roller bearings with higher load rating
  • NSK cage optimised for large taper roller bearings installed in planetary carriers
  • Segmented plastic cage for inner diameters of more than 1000 mm
  • Metric and imperial dimensions
  • Outer diameters up to 2500 mm

Product Benefits:


Axial loads in both directions when arranged in pairsHigh radial and axial loads in one direction

  • Medium speeds
  • Small clearance range when bearing pairs are adjusted during mounting
  • Higher permissible speeds by improved raceway surface roughness
