| Bearing Type | Capacity |
|---|---|
| Ball bearings [3] | Moderate |
| Roller bearings | Heavy |
| Tapered roller bearings | Very heavy |

How to Maintain Axle Bearings

1. Regular Inspection:
Regularly inspect axle bearings for signs of wear, such as excessive play or noise. Early detection can prevent costly repairs.

2. Proper Lubrication:
Ensure that axle bearings are properly lubricated according to the manufacturer's specifications. This helps reduce friction and extend their lifespan.

3. Avoid Overloading:
Overloading your vehicle can put excessive strain on axle bearings, leading to premature failure. Avoid exceeding the recommended weight limit.

Advanced Features of Axle Bearings

In addition to their basic functionality, axle bearings have evolved to include several advanced features:

1. Pre-Load Adjustment:
Pre-load adjustment allows for precise setting of the bearing preload, optimizing performance and reducing noise.

2. Integrated Sensors:
Some axle bearings incorporate sensors that monitor bearing temperature, vibration, and other parameters, providing real-time data for predictive maintenance.
