Double row tapered roller bearings

JOJI double row tapered roller bearings are available in a wide range of designs and types, such as double row tapered roller bearings of the TDI and TDO types, as well as paired single row tapered roller bearings. Depending on the design, the bearings are able to withstand high radial loads and bi-directional axial loads with high rigidity.

  • High radial load carrying capacity
  • Capable of withstanding bi-directional axial loads (except in tandem arrangement)
  • High rigidity
  • Low friction
  • Long service life
