Bushing

A bushing is a common mechanical part, usually installed between components to support, position, or reduce friction and wear. It acts as an “isolation layer” or “protective sleeve” that protects the main components (such as shafts, holes, or connectors) through its wear resistance and cushioning properties, extending the service life of the equipment.

Functions
Support and Positioning: Ensures shafts or moving parts maintain correct position during operation, minimizing misalignment.
Friction Reduction: Provides smooth motion between contacting surfaces, reducing energy loss.
Wear Prevention: Protects critical components from direct wear, thereby extending overall machine life.
Vibration Isolation and Noise Reduction: Absorbs vibration and shock, enhancing operator comfort and equipment stability.
