How to Replace Conveyor Rollers?

How to Replace Conveyor Rollers (Step-by-Step Guide)

Clear, safe, and practical for maintenance teams.

1. Safety First

Stop the conveyor, cut off power, and lock out the control panel.

Place warning signs to prevent accidental startup.

2. Prepare Tools

Wrenches, hammer, screwdriver, gloves.

New matching conveyor rollers.

3. Loosen the Belt

Adjust the tensioner to loosen the conveyor belt enough to lift and remove the roller.

4. Remove the Old Roller

For spring-loaded (quick-change) shafts:

Press one end inward, tilt the roller, and take it out.

For fixed/bolt-on shafts:

Remove brackets or bolts first, then take out the roller.

5. Clean the Installation Area

Remove dust, dirt, and debris from the bracket and bearing seats.

6. Install the New Roller

Place the new roller into the bracket.

For spring-loaded: Compress one end, align, then release to lock.

For bolt-type: Fix bolts evenly (do not over-tighten).

7. Reset Belt Tension & Align

Tension the conveyor belt back to normal.

Check belt alignment to avoid deviation.

8. Test Run

Manually rotate the belt first to confirm smooth rotation.

Restore power and run briefly to check noise, jamming, or belt drift.
