What is a Sheave on a Pulley?

1. Definition

A sheave on a pulley is a grooved wheel or roller used with a wire rope to change the direction of the force applied.

2. Function

The sheave distributes the load evenly across the wire rope, reducing wear and tear.

3. Materials

Sheaves are typically made of metal or plastic, depending on the application.

4. Installation

Sheaves are mounted on a shaft or axle and rotate to guide the wire rope smoothly.

5. Maintenance

Regular inspection and lubrication are essential to ensure the sheave’s proper functioning.
