• Tapered rollers assembled in the bearings are guided by the cone back face rib.

• The raceway surfaces of cone and cup and the rolling contact surface of rollers are designed so that the respective apexes converge at a point on the bearing center line.

• Single-row bearings can accommodate radial load and axial load in one direction, and double-row bearings can accommodate radial load and axial load in both directions.

• This type of bearing is suitable for use under heavy load or impact load.

• Bearings are classified into standard, intermediate and steep types, in accordance with their contact angle (α).
  The larger the contact angle is, the greater the bearing resistance to axial load.

• Since cup and cone assembly can be separated from each other, mounding is easy.

• bearings designated by the suffix "J" and "JR" are interchangeable internationally.

• Items sized in inches are still widely used.
