Lagging for Friction Drive Belts

Product Description

For standard drum motors
High resistance to oil, fuel and other chemicals
Lagging increases friction between drum motor shell and conveyor belt
Lagging prevents slip between drum motor shell and conveyor belt
Longitudinal grooved lagging reduces liquids between belt and shell

Food and hygienic applications
Flat belt, multi V-belt or round belt applications
Centered V-groove for belt tracking facility
Multiple V-grooves for V-belt or round belt conveyors
Hot vulcanisation for high-torque drum motors
Hot vulcanisation is more hygienic

Note: Lagging has an influence on the outer diameter of the drum motor and on the velocity. Belt pull and speed of the drum motor must be recalculated according to the increased diameter.
