Rosta Although we take pride in being “Collar Specialists”, our expertise in sourcing quality products has made Lucas Industrial a valued supplier of other power transmission products as well. First among these are linear bearings with interchanges available for virtually all styles and sizes. Other power transmission products available through Lucas Industrial include leaf chain, roller chain, lumber conveying chain, rigid couplings, ball bearings, and sprockets.The high precise CNC equipment, such as Slow-feeding wire-cut machine, jig grinding machine and electric discharge machine, ensures the top quality precision of mould processing, with the high efficient and environmental protection acid rolling line being the largest raw material converting equipment in the field in china; The wildly use of automatic milling machine, high-speed automatic feeding punch, high speed automatic rolling and assembling machine guarantees the high quality and efficiency of comp1nts and chain & sprocket making. Our capabilities go far beyond the scope of our catalog. Based on customer demand, we now stock solid collars with oversized bores for applications where the standard tolerance does not allow for adequate clearance. We also provide various finishes for solid and split collar including yellow zinc, nickel and chrome. Many are even stocked for off-the-shelf delivery. We also manufacture and stock solid collars with 2 set screws, with thru holes, and without holes. Collars are available in inch and metric sizes. Heavy series clamp-type collars and threaded collars are also available. We can even provide square bore collars for quantity requirements. And if your special requirements repeat regularly, we are glad to stock parts for scheduled releases. Whatever your collar requirements, Lucas Industrial is your supplier for high quality cost – effective comp1nts.SEB27 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 06021004 SEB-2710si1r serves 3 purposes; a torsional spring, a pivot bearing, and an anti-vibration mount. The true advantages of a ROSTA SEB2710si1r 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 SEB27 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-27 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.
