Polyurethane Lagging

Elastotec Polyurethane Lagging is used to increase the service life of non-drive pulleys. Polyurethane’s extreme abrasion resistance combined with its low coefﬁcient of friction provide a solution to applications with premature wear when there is a requirement for no risk of damage to the belt cover.

Polyurethane is good for applications with carry back problems as it is slippery, resisting material build up. Polyurethane Lagging is a specially engineered molded thermoplastic polyurethane, inserted onto a rubber backing layer.

Description

Description

Application

Polyurethane lagging shall be speciﬁed on non-drive pulleys when:

There’s a requirement for higher abrasion resistance than what achieved with rubber laggings.
In applications where there’s slippage between the conveyor belt and the lagging surface, such as on bend pulleys and non-drive pulleys on turnover conveyors. Its low coefﬁcient of friction make Polyurethane Lagging kind to the belt bottom cover.
When there’s buildup of material between the belt and the lagging.
