ROSTA SEF15 Tensi1r Technology

At the core of every ROSTA10si1r lies a special rubber compound that conforms to ISO 14001 with a unique ability to provide the consistent10sioning 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 ROSTA10si1r.

SEF-15 Mounting Instructions

Tensi1r MountingTighten 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 menti1d 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 the10si1r, 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 Tensi1rsIn very long chain & sprocket and belt drives it was
recommendable to install on the slack-side several10si1rs, in order to compensate for occurring elongation. The “Boomerang” with its bent double-arm equipped with 2 chain & sprocket sprockets or a combination of grooved pulley and flat-roller (belt-drives)
offers a triple-compensation of chain & sprocket and belt elongations, due to S-shape contact-arc.
