YLCM Bearings – FAQs for Construction Machinery Applications

1. What types of bearings are commonly used in construction machinery?

Construction machinery relies on various types of bearings, each designed for specific functions:

Spherical Plain Bearings: Ideal for pivot points and oscillating movements in hydraulic cylinders and articulations.

Needle Roller Bearings: Suitable for high-load, compact spaces such as transmissions and gearboxes.

Ball Bearings: Used in rotating shafts, motors, and wheel hubs to reduce friction and support radial and axial loads.

Spherical Sliding Bearings: Designed for heavy loads and slow oscillating movements, often in crane joints or large pivot points.

Tapered Roller Bearings: Perfect for handling combined radial and axial loads in final drives, axles, and wheel hubs.

Cylindrical Roller Bearings: Support high radial loads in heavy-duty rotating machinery like conveyor rollers and gearboxes.

Bearing Races and Housings: Provide structural support and secure alignment for various bearing types.

2. How do I choose the right bearing for my construction equipment?

Selecting the correct bearing depends on:

Load type and magnitude: Radial, axial, or combined loads determine the bearing type.

Operating conditions: Temperature, vibration, speed, and environmental exposure affect material and design selection.

Compatibility: Check machinery specifications and part numbers to ensure the bearing fits precisely.
