Separate Inspection

Each sheave pulley is individually inspected to guarantee quality before being released for sale.


After inspection, the sheave pulley is marked with relevant information for identification and traceability.

How do you adjust sheave pulleys?

1. Loosen the Set Screw

Start by loosening the set screw that secures the sheave to the shaft.

2. Adjust Position

Move the sheave along the shaft to the desired position for belt tension adjustment.

3. Tighten Set Screw

Once the position is adjusted, tighten the set screw to secure the sheave in place.

4. Check Alignment

Ensure that the sheave is properly aligned with other components for smooth operation.

5. Verify Tension

Check the tension of the belt or chain after adjusting the sheave to ensure optimal performance.

6. Test Operation

Run the machinery to test the operation of the sheave pulley after adjustment.

7. Fine-tune if Necessary

If needed, make further adjustments to the sheave pulley for optimal performance.
