A lagging forvery strong adhesion of the pulley to the belt
The ceramic lagging is extremely effective in wet or muddy environments, where slippage on the conveyor belt is sometimes observed. Ceramic inserts increase grip and friction between the head pulley and the belt, while offering very high abrasion resistance.
Different ceramic laggings for different applications
Square ceramics
For heavy-duty applications thanks to their 15mm thickness, which withstands high stresses and strains. By increasing the coefficient of adhesion, ceramics reduce slippage between the belt and the conveyor drum.
2 rubber grades for square ceramics :
- Anti-abrasive: this coating for conveyor pulleys is highly resistant and long-lasting.
- ISO 284/340: for ATEX applications, this lagging features antistatic and self-extinguishing properties.

Other profile types
Diamond
The universal lagging
Used on bend pulley and take up pulley. It is also suitable for head pulley.
Smooth
Protective lagging
For conveyor pulleys that don’t drive the belt, to extend their service life.
Slide Lag
For high tensile forces
Its elastomer composition gives drive or head pulleys high tensile strength.
Pulley bars
Anti-skid lagging for large and heavy duty conveyor pulleys
Ruggedly designed, the anti-skid bars are made of wear-resistant rubber for long life.
Griplag
For tough conditions
The Griplag prevents slippage and is self-cleaning, preventing material build-up and misalignment.
VARIOUS LAGGING AND PREPARATIONS
Hot vulcanization
Vulcanisation is a chemical process that gives the drum pulley lagging greater tensile strength, swelling, abrasion resistance and elasticity.
Cold rubberising
Cold rubber bonding is generally used on "classic" drum pulleys for rubber coatings with smooth, diamond-shaped ceramic inserts.
Special rubberizing
Coatings such as Slide Lag, Pulleybars or Griplag are applied to conveyor drums and conveyor pulleys by mechanical assembly.
Shot-blasting
All coated conveyor pulleys are shot-blasted for improved surface preparation. This preliminary work is essential for optimum adhesion to the conveyor belt pulley.
