Design features:

Compared to non-lag pulleys, the coefficient of friction can be up to twice as high.

Higher coefficient of friction by up to 50% than typical rubber lagging.

38% of the belt's contact surface is ceramic (Medium Duty).

Virtually eliminates belt slippage.
Improves belt tracking.
Easily sheds water and dirt.
Lower belt tension and less take-up weight.

Easy installtion.

More details:

It is particularly well suited for pulleys where slippage and severe wear and tear issues render typical rubber lagging useless. The alumina ceramic tiles support the belt's optimal grip in muddy, rainy, or other challenging conditions.
