Rosta Standard strands have an even number of pitches, pin links, and roller links. A roller chain strand can be shortened by removing links and lengthened by adding whole or a half links (offset links).specialize in power transmission products,pto shaft, agricultural gearboxes , CATV products, mechanical seal, hydraulic and Pheumatic, and promotional products.engineering class chain & sprockets & precision roller chain & sprockets. Single strand chain & sprocket, multi-strand chain & sprockets, double pitch chain & sprockets, corrosion resistant chain & sprockets, self-lubricating chain & sprockets, attachment chain & sprockets, leaf chain & sprockets, and specialty chain & sprockets.SEI15 Stainless Steel Tensi1r device is not only a modern engineering marvel but is also a maintenance-free10sioning device that is utilized throughout the world for the various belt and roller chain & sprocket applications. The 61030024 SEI-1510si1r serves 3 purposes; a torsional spring, a pivot bearing, and an anti-vibration mount. The true advantages of a ROSTA SEI15 stainless steel10si1r 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. Being manufactured from high-quality stainless steel means that the10si1r can operate in a wide range of harsh environments ranging from wash-down to highly corrosive, and temperatures ranging from -40 to +176 degrees Fahrenheit. for over 45-years ROSTA has produced some of the highest quality and longest-lasting dampening and10sioning devices on the market!

ROSTA SEI15 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.

SEI-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.
