Spherical Roller Thrust bearing

1. Product Description

The Spherical Roller Thrust Bearing is designed to support high axial loads, and they can accommodate angular misalignment due to their spherical roller design. These bearings are well-suited for applications where both radial and axial loads are encountered. Commonly used in heavy machinery, automotive, and industrial applications, they ensure a high level of reliability and performance.

Manufactured by Adarsh Bearings Pvt. Ltd., under the Locus Brand, these bearings are produced with precision to meet stringent quality standards.

3. Working

The Spherical Roller Thrust Bearing operates by supporting the axial load between its spherical rollers, which are arranged in a spherical raceway. The rollers roll smoothly within the inner and outer races, allowing the bearing to handle axial loads, and a limited amount of radial load, with the ability to accommodate angular misalignment.

4. Principle

The bearing works on the principle of rolling friction where the spherical rollers are arranged at an angle to the axis of rotation. This design allows the bearing to handle high axial loads while maintaining rotational stability. The spherical nature of the rollers permits the bearing to adjust to misalignment and increases the overall reliability and lifespan of the bearing.

5. Assembly

1. Insert the Inner Race: Place the inner race (shaft race) in the bearing housing.
2. Add the Spherical Rollers: Position the spherical rollers between the inner and outer races.
3. Install the Outer Race: Position the outer race in the housing and secure it.
4. Sealing: Attach the seals to prevent the ingress of dust, dirt, and contaminants.
5. Lubrication: Apply grease or oil, ensuring proper lubrication for smooth movement and to avoid wear and tear.

6. Installation Process

1. Clean the Assembly Area: Ensure the installation surface is free of contaminants.
2. Pre-Lubrication: Lubricate the bearing with suitable grease or oil before installation.
3. Align the Shaft and Housing: Ensure proper alignment of the bearing on the shaft or in the housing to avoid misalignment.
4. Secure the Bearing: Secure the bearing using the appropriate locking mechanism or retention hardware.
5. Test Functionality: After installation, rotate the shaft manually to check for smooth operation.
