Rosta corrosion- and wear-resistant coiled tubing injector roller chain assemblies for the oil and gas industries. Available in single and double pitch drive chain types with various sizes and power rating. Features include zinc-nickel and non-hexavalent chromate protective exterior coating, electrochemically bonded, and interference fit cover plates.With many years’ experience in these lines, we have been distinguished from other suppliers in China by our advantages in competitive pricing, on-time delivery, prompt responses, on-hand engineering support and good after-sales services. Standard strands have an even number of pitches, pin links, and roller links. A roller chain & sprocket strand can be shortened by removing links and lengthened by adding whole or a half links (offset links).SEB18 Boomerang 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 06021003 SEB-1810si1r serves 3 purposes; a torsional spring, a pivot bearing, and an anti-vibration mount. The true advantages of a ROSTA SEB1810si1r 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 boomerang style10si1r serves its purpose in applications that require10sioning of very long chain & sprocket and belt drives, for over 45-years ROSTA has produced some of the highest quality and longest-lasting dampening and10sioning devices on the market!

ROSTA SEB18 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.

SEB-18 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.
