Expertise in vulcanized lagging for every conveyor drum pulley
Vulcanization is a chemical process by which the physical properties of the rubber/metal bond are improved. The vulcanised lagging on the drum pulley provides greater tensile strength, resistance to swelling, improved abrasion resistance, and enhanced elasticity.
The advantage is a seamless lagging, avoiding weak points. What’s more, the polymerization between the rubber and steel prevents any risk of delamination. These features make them ideal for high-temperature product transport applications.

Profile types
Diamond
The universal lagging
Used on deflection and take up pulley. It is also suitable for head pulley.
Ceramics
The high-adhesion lagging
Effective in humid environments to prevent slipping on the conveyor belt.
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 head or drive pulleys high tensile strength.
Pulley bars
Anti-skid lagging for large drums
Ruggedly designed, the anti-skid bars are made of wear-resistant rubber for long life.
Griplag
For tough conditions
The GriplagⓇ prevents slippage while being self-cleaning, preventing material build-up and misalignment.
The benefits of rubber lagging
- Bonding systems that make installing pulley rubber easy, fast and tailored to your needs.
- The lagging protect the belt and significantly improve the conveyor’s overall performance, thus extending its service life.
- They ensure that rollers and drum pulleys rotate smoothly without clogging, thus maintaining and aligning the conveyor belt.
- Rubberized pulleys protect the belt by reducing slippage between belt and pulleys.
- They reduce the belt’s operating tension, thus reducing belt elongation.
- They reduce conveyor noise and vibration.

Other lagging and preparation
Cold rubberizing
Cold rubber bonding is generally used on “classic” drum pulleys for rubber coatings with smooth, diamond-shaped ceramic inserts.
Special rubberising for conveyor pulley
Coatings such as Slide Lag, Pulleybars or Griplag are applied to conveyor drums and conveyor pulleys by mechanical assembly.
Shot-blasting
All coated pulleys are shot-blasted for improved surface preparation. This preliminary work is essential for optimum adhesion to the conveyor belt pulley.
