ROLL-RING tensioning rings
The ROLL-RING tensioning ring is a unique product from the manufacturer RENOLD, which is used for tensioning chains without using standard tensioners. The self-adjusting ring made of a special polymer with chain gearing rolls between two strands of the chain drive, thereby creating the required pre-tension. It can be used in both horizontal and vertical planes. It is particularly suitable where checking the chain tension is impossible or difficult in terms of access.
