Needle Thrust Roller Bearings

The performance of needle thrust roller bearings is similar to cylindrical thrust roller bearings. As the length of the needle roller is small, the friction is high, and the speed is low. But the axial dimension is smaller than the cylindrical thrust roller bearing, and the load capacity is ample. Needle thrust roller bearings are divided into one-way needle roller bearings and two-way needle roller bearings according to the number of bearing roller rows. No angular error is allowed when installing needle thrust roller bearings.

Features of needle thrust roller bearings:

The uniqueness of a needle thrust roller bearing is its rollers, which are lengthy and have a small bore diameter. Unlike the other types of approaches, they are smaller in size and have several inherent features mentioned below:

  • Manage heavy axial loads and peak loads:

With slight deviation in the diameters of rolling elements, you can have the bearing handle not only heavy axial loads but also peak loads.

  • Have extended service life:

These bearings are generally designed to have reduced stress peaks, which are made possible by slightly relieving the roller ends. The bearing alters the line contact between the rollers and rings, which minimizes or avoids stress peaks and gives long life.

  • High rigidity:

The number of rolling needle elements and the reduced “load carriage per unit area” increases the stiffness of the bearing.

Applications of needle thrust roller bearings:

Here are examples of applications in which needle thrust roller bearings might be used:​

  • Machine tools
  • Cars and light trucks
  • Trucks, trailers, and buses
  • Two and three-wheelers
