About Trellex® ceramic pulley bar


Trellex ceramic pulley bar is used in applications that require an easy installation and operation. Benefits include the application and removal of the lagging without removing the drum or belt from the conveyor system. It is fastened with self-tapping M8 screws directly onto the pulley shell, so it's easy to install without removing belt or pulley.


Trellex ceramic pulley bar is made of hardwearing rubber with high-quality aluminum oxide ceramics and this product has the perfect combination of elasticity and rigidity. The ceramic inserts is made of an extremely hardwearing material, which improves the grip between the lagging and the belt. The round shape of the ceramic inserts eliminates sharp edges to avoid damage to the belt.

Use this formula to determine if pulley bars can be used:

F =    P  

P = power (kW)
h = belt speed (m/s)
D = pulley diameter (m)
B = pulley width (m)
F should not exceed 130.


Shape is designed to suit all pulley diameters:
