Pressure rollers and tensioner rollers

Pressure rollers and tensioner rollers are mounted on a tensioner arm to press against a belt or chain with a smooth cylindrical surface. They work well with V-belts and flat belts and wherever a chain is tensioned from its back side.

Pressure rollers and tensioner rollers - a larger wrap angle and a reliable belt drive

A roller working on the slack side of the belt increases the wrap angle of the pulley, so the belt slips less and transmits power more reliably. An arm with a roller compensates for belt elongation by itself, so there is no need to reposition the motor periodically. The smooth surface does not damage the back of the belt or chain.

RP pressure rollers and RU tensioner rollers matched to tensioner arms

RP pressure rollers and RU tensioner rollers in several sizes, matched to the size of the tensioner arms. The roller dimensions are given on the product page.
