Renold Jeffrey Self Adjusting Chain Tensioner ROLL-RING®

Description
ROLL-RING® 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-RING® deforms to an elliptical shape, due to compression between the strands and completely asborbs any slack in the system. ROLL-RING® performs the job of a tensioner and a damper in one, and is ideally suited to applications where maintenance is difficult or impossible. ROLL-RING® chain tensioners provide tensioning using: Static tensioning force from the elastic ring• Dynamic tensioning force from the damping of the working material ROLL-RING® 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-RING® chain tensioner with its individual allocations of tensioning forces and their resulting effects. Benefits The ROLL-RING® chain tensioner provides cost effective, time saving installation and maintenance. The advantages over other types of chain tensioners are: Free standing - no sprockets, bolts, plates, drilling or costly installation required. The ROLL-RING® is easily installed where space limitations prohibit the use of conventional chain tensioners. The ROLL-RING® is fitted in a matter of seconds. It is ready for use without any tools, tensioning equipment or any further alignment or adjustment. It is fully effective in vertical and diagonal drives. The ROLL-RING® works automatically, is maintenance free and self lubricating. It can be used in dusty and dirty environments. The ROLL-RING® is a tensioner and damper in one, thus reducing noise levels. ROLL-RING® also works in reverse mode. ROLL-RING® chain tensioners reduce chain wear and improve the quality and efficiency of the complete chain drive.
