NTN double row tapered roller bearings in the TDO and TDI designs, in many variants and with different features. Depending on the design, these bearings can accommodate heavy radial loads, axial loads in both directions and have a high degree of stiffness.

 

The inner and outer rings can be separated to facilitate assembly, and both can be fitted tightly.On types with no ribs, either the inner or the outer ring can move freely in the axial direction, making cylindrical roller bearings ideal for use in free side bearings that absorb shaft expansion.On types with ribs, the bearing can bear a slight axial load between the roller end surfaces and the ribs.Depending upon the contact angle, tapered roller bearings are divided into three types; normal angle, medium angle, and steep angle. Double-row and four-row tapered roller bearings are also available. Pressed steel cages are generally used. For metric-design medium-angle and steep-angle tapered roller bearings.
