Chain Drive Tensioning

Any chain drive requires a tensioning system to compensate for elongation and ensure smooth and quiet operation. Without adequate tensioning, Chain drives are susceptible to increased wear and premature failure. Automatic tensioning optimises chain drive performance and lifespan.


ROSTA SE tensioners and accessories provide you with a simple to install solution which continuously applies tensioning force to the chain drive without the need for manual adjustment, and as with all ROSTA products with zero maintenance.
