Dip angle and composition requirements of the heim joint rod end

- Jun 12, 2019-

The heim joint rod end is characterized by high load capacity and impact resistance when used, and has the characteristics of corrosion resistance, wear resistance, self-aligning, lubrication or self-lubricating and non-lubricating dirt during use, even if the installation is misaligned. Also works fine. Therefore, the heim joint rod end is widely used for low-speed oscillating motion, tilting motion, and rotational motion.

Dip angle of the heim joint rod end

The inclination of the heim joint rod end is much larger than that of the generally adjustable rolling bearing. It is suitable for use in the support part with low concentricity. The inclination of the joint bearing varies with the size, type, sealing device and support form of the bearing. The inclination angle of the radial spherical plain bearing is 3° to 15°, the inclination angle of the angular contact joint bearing is 2° to 3°, and the inclination angle of the thrust joint bearing is 6° to 9°.

Mating of the  heim joint rod end

In any case, the joints selected for the joint bearing shall not cause uneven deformation of the ferrule. The selection of the mating nature and grade must be determined according to the working conditions such as bearing type, support form and load size.

Connector rod end composition

The joint bearing is mainly composed of an outer ring and an inner ring. The inner spherical surface of the outer ring and the outer spherical surface of the inner ring constitute a rolling friction pair.
