Conveyors
Pulley lagging compared: rubber vs ceramic vs vulcanised
Reviewed August 2026
Short answer
Use diamond-grooved rubber lagging on general drive and non-drive pulleys in dry duty. Use ceramic (embedded-tile) lagging on drive pulleys in wet or high-tension duty where slip and wear are the problem — it gives the highest friction and the longest life. Choose the application method — hot-vulcanised, cold-bonded, weld-on or slide-on — by whether the pulley can leave the conveyor.
Lagging does two jobs: it gives the drive pulley grip so the belt does not slip, and it protects the pulley shell. Pick the type on the duty, and the method on the access.
Types
- Plain rubber, diamond-grooved — general drive and non-drive pulleys, dry duty. The default.
- Ceramic (embedded tiles) — drive pulleys in wet or high-tension duty. Highest friction and wear life; heavier and more expensive. Available in full-coverage or dimpled patterns.
- Rubber on non-drive pulleys — thinner, protective; often plain (ungrooved) on bend and tail pulleys.
Application methods
- Hot-vulcanised — strongest bond, workshop only
- Cold-bonded strip — good bond, can be done in situ with the right prep and temperature
- Weld-on ceramic pads — fast field fitment onto a steel shell
- Slide-on sleeve — a pre-made lagging sleeve pulled over the pulley face
What to send us
The pulley face width and diameter, whether it is a drive or non-drive pulley, the belt tension or drive power if known, the material (wet or dry), and whether the pulley can come off the conveyor. We match the lagging type, pattern and method.
