The 61030022 SER-1510si1r serves 3 purposes; a torsional spring, a pivot bearing, and an anti-vibration mount. The true advantages of a ROSTA SE15W Reinforced Lever Arm10si1r versus look-alikes are the patented specially engineered material that is within every10sioning device made by ROSTA, cost advantage, overall durability, and solid performance on high productivity productions lines. The Reinforced Lever Arm and inner core are specially welded for use in even the toughest applications, such as combustion engines and even compressors! for over 45-years ROSTA has produced some of the highest quality and longest-lasting dampening and10sioning devices on the market! For more information or to get a quote on the SER1510si1r please contact us and we will be happy to assist you.

ROSTA SER15 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.

SER-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.
