ROSTA SE45 Tensioner Technology


At the core of every ROSTA tensioner lies a special rubber compound that conforms to ISO 14001 with a unique ability to provide the consistent tensioning force with minimal impairment to the material its self. ROSTA is the only company capable of producing this specific material, this is why no "interchange" can withstand the same life-span as a ROSTA tensioner.

SE-45 Mounting Instructions

Tensioner Mounting

Tighten the flange screw slightly. Grip the housing with flat-wrench and set needful pre-tension by rotating the housing in the required direction. Tighten the central screw according to the above mentioned tightening moment MA. Position flat-wrench close by the flange-bottom.
Z-configuration of Sprockets or Riders

If there is the need to install sprockets, riders or rollers on the outer arm-side of the tensioner, then the distance "Z" should be as little as possible to avoid misalignment in element parallelism. Furthermore, the pre-tension force should not exceed 50% of the capacity = max. the pre-tension angle of ~ 20°.
Use of SE-B Boomerang Tensioners

In very long chain and belt drives, it was recommendable to install on the slack-side several tensioners, in order to compensate for occurring elongation. The "Boomerang" with its bent double-arm equipped with two chain sprockets or a combination of grooved pulley and flat-roller (belt-drives) offers a triple-compensation of chain and belt elongations, due to S-shape contact-arc.
