- A mining company extended conveyor belt life by 20% by implementing a rubber cutless bearing with built-in sensors for predictive maintenance.
- A wind turbine operator reduced maintenance costs by 30% by using a composite cutless bearing with a long service life.
Effective Strategies, Tips and Tricks
- Proper Installation: Ensure accurate alignment and secure fastening.
- Regular Maintenance: Inspect, lubricate, and replace bearings as recommended.
- Avoid Abrasive Environment: Protect bearings from sand, grit, and other abrasive particles.
- Consider Lubrication Systems: Incorporate automatic lubrication systems to extend bearing life.
Common Mistakes to Avoid
- Overloading: Do not exceed the specified load capacity of the bearing.
- Insufficient Maintenance: Neglecting maintenance can lead to premature failure.
- Incorrect Installation: Misalignment or loose fastening can compromise bearing performance.
- Exposure to Abrasives: Allow contact with sand or grit can accelerate wear and tear.
