Types of Sheave Pulleys

1. Fixed Pulleys

Fixed pulleys have a stationary axle and are used to change the direction of force in a system.

2. Movable Pulleys

Movable pulleys have a freely moving axle and are used to provide mechanical advantage in lifting systems.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to increase the mechanical advantage even further.

4. Snatch Blocks

Snatch blocks are pulleys that can be opened on one side to easily insert a rope or cable without threading.

5. Timing Pulleys

Timing pulleys have teeth that mesh with the teeth of a timing belt to provide precise synchronization of shaft rotation.

6. Rope Pulleys

Rope pulleys are specifically designed for use with ropes and cables to facilitate lifting and pulling operations.

The design of the sheave pulley is created in a mold to ensure precision and consistency.


The molten material is poured into the mold to form the shape of the sheave pulley.

Raw Materials:

High-quality materials are used to manufacture sheave pulleys for durability and performance.


The sheave pulleys are manufactured using advanced machinery and processes to meet industry standards.


Each sheave pulley undergoes rigorous testing to ensure quality, performance, and safety standards are met.

Antirust Treatment:

Sheave pulleys are treated with anti-rust coatings to protect them from corrosion and extend their lifespan.

Separate Inspection:

Every sheave pulley is individually inspected to guarantee it meets the required specifications and standards.


Each sheave pulley is marked with specific information for identification and traceability purposes.

How do you adjust sheave pulleys?

1. Tension Adjustment:

Adjust the tension of the belt or rope on the sheave pulley to prevent slipping and ensure proper power transmission.

2. Alignment Correction:

Check the alignment of the sheave pulleys to ensure smooth operation and prevent premature wear.

3. Lubrication:

Regularly lubricate the sheave pulleys to reduce friction and extend their lifespan.

4. Inspection:

Periodically inspect the sheave pulleys for any signs of wear, damage, or misalignment that may require adjustment.

5. Cleaning:

Clean the sheave pulleys to remove dirt, debris, and buildup that can affect their performance.

6. Consultation:

If unsure about adjusting sheave pulleys, consult the manufacturer’s guidelines or seek professional assistance.
