2009 BK Series Catalog from R+W

Stainless steel bellows couplings have grown more prevalent, driving the development of a wide variety of mounting configurations, wall thicknesses, lengths, torque ratings, etc.

The 2009 BK series catalog from R+W represents the latest collection of standard bellows coupling designs for applications requiring torque ratings from 15 Nm – 10,000 Nm. Flanges, shafts, hollow bores and nearly any other mechanical interface are accommodated.

Safety Coupling Catalog

Zero-Max has published a 12-page Zero-Max catalog of Torq Tender overload safety couplings. These overload safety couplings disengage motor drives for overload protection. They protect motor and drive systems from jam ups and excessive loading.

System designers will find this new catalog helpful when examining overload protection options for a particular system design. Available in models that will disengage torques from 2 to 3,000 in. lbs., mechanically operated Torque Tenders often are the best design option because they are tamper proof and do not require costly and potentially risky calibration procedures. The torque value is controlled by the Torq Tender part number ordered and preset at the factory.

Torq Tender operation in most mechanical power transmission systems is simple. When the load exceeds the Torq Tender rating preset with precision tempered torque springs, the unit’s drive key pivots out of a slot, disengaging the Torq-Tender coupling. Once the overload is removed and the speed reduced, the Torq Tender resets itself automatically. This automatic resetting action engages the system’s drive shaft and puts the entire drive system back into motion at its original position.

Torq Tenders are available in many standard sizes. The smallest is the TT1X with a 2 to 60 in. lbs. torque rating. The largest is the TT4X with a 750 to 3000 in. lbs torque rating. Special Torque Tender designs are also detailed in the new catalog for handling various mountings, bore sizes and housings.

Inside the new brochure is complete selection and ordering information. Also, you can now size, select and see the right Torque Tender solution with Zero-Max Partstream, the configurable 3D CAD downloads.
