Bearings are high precision parts. Therefore, improper handling will lead to premature bearing failure. Use caution when handling bearings during installation.
According to SKF and Maintenance.org, 16% of all premature bearing failures result from improper or inadequate assembly and assembly, for example using brute force.
This is a surprising statistic, especially when it comes to a problem that can be easily avoided through proper education and basic training.
Improper assembly is often caused by improper bracket installation. Typically, the correct way is to mount a press-fit bearing to the slewing ring.
Other common assembly errors include:
- Using brute force (i.e. applying pressure or blows to the outer race) to fit the bearings onto the shaft
- Pressing the inner ring to fit the bearings into a housing
- Incorrectly sized shafts or housings (e.g. too loose or too tight)
These errors can cause: dents, cracked rings, premature wear, premature fatigue and, ultimately, premature bearing failure.
Bearings must be assembled in a clean work environment to ensure the absence of contaminants. Correct tools and procedures must be used. This is important to extend the life cycle of the bearing.
The precise tools and procedures required to install a bearing vary depending on size, type, speed, application and industry. Our experienced engineers will work with you through professional consultation and recommendations for correct assembly and disassembly to extend your machine's uptime.
