The German couplings specialist R+W has developed a safety clutch which, it claims, is 60–70% lighter than conventional designs, and allows smaller clutches to be used in some applications. The SL series clutch, which made its debut at the recent Motek exhibition on Germany, is the result of a two-year collaborative project with universities. The […]

Couplings Target High Corrosion, Long Service Applications
Eaton Corp. developed a new series of ISO 16028 stainless steel quick-disconnect/non-spill couplings incorporating standard anti-extrusion Teflon seals and Viton O-rings. The new FD89 – 2000 Series couplings provide with push-to-connect latching, flush-face valving and incorporate a safety sleeve lock. They are targeted toward applications that require corrosion resistance and long service life, the company said. The […]
Torque Limiters Allows For Rapid & Automatic Recovery
R+W America’s new torque limiter, the SL Series, utilizes a proven spring-loaded ball detent system, along with a previously patented preload for zero-backlash operation. To achieve its target of 50-percent weight reduction, R+W embarked on a two-year collaborative effort with local universities, designing the product from the ground up rather than simply redesigning or optimizing […]
Stainless Steel Couplings Deliver Non-Spill Connections
The FD89 – 2000 Series couplings meet ISO 16028 dimensional requirements. These stainless steel quick-disconnect/non-spill couplings feature standard anti-extrusion Teflon® seals and Viton® O-rings. “FD89 couplings provide a globally interchangeable solution for a variety of applications that require both corrosion resistance and long product life,” explained Joseph E. Dzierwa, Eaton product manager, connectors. “They’re machined […]
Low inertia miniature couplings deliver high torsional stiffness
The 16 mm diameter size Servo Class coupling has operating torque of 4.43 in.-lb in both single (SD) and double disc (SC) models. They suit applications that need high torsional stiffness and low inertia. The SD005 model delivers 43.3 torsional stiffness and 0.0009 in.lb2 moment of inertia. The SC005 model delivers 30.5 torsional stiffness and […]
Low weight, low inertia torque limiter
By Tobias Wolf, Product Engineer, R+W GmbH and Andrew Lechner, Product Manager, R+W America. The concept of weight reduction through the use of high tech materials is not a new one. But for those involved in the design of motion control and automation systems, the elimination of excess mass and inertia is often the difference […]
