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.
Key features and benefits
- Highly abrasion resistant polyurethane inserts prevent wear on pulley shell and offers positive dirt release and shedding.
- Precision moulded strip with optimum polyurethane properties.
- Supplied in strip form 250mm wide for easy handling.
- Strips packed in plastic film to preserve buffed bonding layer ready for application.
- Coloured TPU inserts.
- Low coefficient of friction difficult to stick to, resists build up and is kind to belt cover.
Design
Elastotec Polyurethane Lagging is 250mm wide to ensure easy handling and application. It is supplied in long roll lengths that fit on standard sized pallets to eliminate waste and for cost effective transportation and storage. It can be supplied in thicknesses from 10mm to 20mm.
