Pully Lagging - KC Supply Co.

“Lagging” is the term used to describe the application of a coating or cover applied to a pulley. As more conveyor systems are being built to go faster with increased capacity, the importance of pulley lagging is obvious.

Lagging is often applied in order to extend the life of the pulley by providing a replaceable wearing surface or to improve the friction between the belt and the pulley, thereby preventing costly maintenance and replacement of damaged pulleys. It also can reduce the chance that a belt will slip. Slipping belts will wear out, cause fires and damage your equipment. There are three common types of lagging used on pulleys:
1. Rubber – This lagging is soft and won’t damage the belt but also does not have a long lifespan. Drive pulleys are often rubber-lagged to improve the friction between the conveyor belt and the pulley.
2. Ceramic – This lagging is used in instances where the pulley operates in extremely aggressive conditions.
3. Replaceable strip – This lagging comprises a series of steel support strips, which are welded or bolted to the pulley. The lagging material, which is either rubber or ceramic strips, is then slid into the steel retaining strips to provide lagging on the pulley.

Pulley lagging lowers maintenance costs, minimizes downtime, extends the life of pulleys, easy to install and replace, and is self-cleaning. The only maintenance pulley lagging requires is

• Regularly inspecting and monitoring its condition
• Repairing local damage before it affects other areas
• Ensuring that re-lagging of pulleys is done by experienced personnel to maximize the life of the lagging
• Having a spare pulley available so that a damaged pulley or damaged lagging can be removed from service
