■Application:
The DuraLagging® ceramic pulley lagging is constructed from hundreds of individual ceramic tiles molded into a
durable rubber backing.The ceramic lagging can significantly increase drive traction between the belt and the
pulley, which in turn reduces load and wear on the drive, belt, pulleys, bearings and take-up.
