Crossed roller bearings failure may be caused by various reasons. Improper operation, insufficient lubrication, rust and corrosion, and some other factors such as external materials, eccentricity, etc., all will cause a great reduction of bearings service life. Therefore, it is necessary to have sufficient knowledge and understanding of bearing failure precautions during the application.

Crossed Roller Bearings Failure Reasons and Precautions

1. Insufficient lubrication

Insufficient or improper lubrication may cause component scratches or severe bearing deformation. Precautions: Improve the lubrication system and regularly replenish or replace the lubricant appropriately. (Check how to lubricate crossed roller bearings)

2. Non-standard operation of crossed roller bearing

Improper installation, operation, or disassembly of crossed roller bearings may cause deformation or defect of the cage. Precautions: Use correct operating methods, suitable installation, and removal tools. (Learn how to install crossed roller bearings.)

3. Bearing rust and corrosion

Contact with water may cause corrosion and rust of bearing components. Crossed roller bearings with corrosion may cause flaking during operation. Precautions: Check the seal regularly to ensure a good sealing effect and store the bearings correctly. (Check how to prevent crossed roller rings from rust.)

4. Electric current

If crossed roller bearings are energized while rotating, it may cause grooves or nicks. If the bearing is static, improper grounding of electrical operations can cause minor burns. Precautions: Reduce or avoid electric current passing through the bearing through proper ground connection before welding parts other than the bearing.

5. Bearing external materials

Abrasive particle contamination and debris intrusion may cause wear, scratches, and dents on the working surface of the crossed roller bearing. Precautions: Clean bearings surface and internal, remove intrusive particles and debris, replace lubricants, and check the sealing system.

6. Bearing eccentricity

Crossed tapered roller bearings eccentric, inclined or excessive load may cause geometric stress concentration or surface spalling. Precautions: Use precision machining machine tool bearing seats and shoulders.
