Self-adjusting chain tensioner
ROLL-RINGŪ is a simple yet innovative chain tensioner made from a specially formulated polymer. The unique design is based upon a simple toothed ring that can be fitted to horizontal, vertical or diagonal drives in a matter of seconds, simply by placing it in-between the two strands of chain.
When the drive is in use, the ROLL-RINGŪ deforms to an elliptical shape, due to compression between the strands and completely absorbs any slack in the system. ROLL-RINGŪ performs the job of a tensioner and a damper in one, and is ideally suited to applications where maintenance is difficult or impossible.

ROLL-RINGŪ chain tensioners provide tensioning using:
ROLL-RINGŪ provides as much tensioning as possible at low chain speeds, and has reserves of tensioning and damping capability for higher chain speeds. The diagram below shows the tensioning force of a ROLL-RINGŪ chain tensioner with its individual allocations of tensioning forces and their resulting effects.
The ROLL-RINGŪ chain tensioner provides cost effective, time saving installation and maintenance.
The advantages over other types of chain tensioners are:
