Precautions for Proper Handling of Rolling Bearings

Rolling bearings are used under various operating conditions with a wide variety of light to heavy loads. Since they are manufactured to a high level of accuracy, they must be handled carefully and properly; the purpose for which they are used is just as important as careful handling.

Incorrect mounting and improper handling are the most common causes of premature failure. Consequently, it is clear that proper handling, as well as appropriate selection and usage, are essential. Instructions for the proper handling of rolling bearings are summarized as follows:

1. Keep bearings and related components clean.

2. Confirm that the dimensions and finish of related components are correct for the desired use.

3. Keep bearings free from harmful substances, including foreign particles and moisture.

4. Be sure to mount bearings in compliance with their designed purpose and specified operating conditions.

5. Use the proper tools for mounting and dismounting.

6. Exercise care to not damage or distort bearings in the course of mounting and dismounting.

7. Use the correct quantities of the appropriate lubricant.

8. Keep hands as clean as possible when handling bearings to prevent corrosion. Wearing gloves, if possible, is recommended.

Although sophisticated devices are not necessarily required for handling bearings, proper tools should be used depending on specific circumstances to facilitate work operations and ensure flawless performance. Obviously, engineers who engage in design and inspection must also be well versed in the proper handling and mounting methods in conformity with the intended use of the bearings. The goals of proper handling are to protect the bearings from any potential damage and ensure they serve their intended uses as effectively as possible.
