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 […]

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 […]
High Torque Motor Turns At Speeds Up To 3,500 RPM
Today’s turning centers can be economical without sacrificing power or precision. Demonstrating this is the Lynx 300, a new turning center from Doosan that’s just now entering the United States. The Lynx’s 20 Hp, high torque motor provides the power for heavy cuts and the speed to produce near-mirror finishes. Its 10″ diameter 3-jaw power […]
Slip Systems for Wind Turbine Generator Protection
CENTA produces an enhanced version of its Torque Hub, the slip clutch which offers a simple and low-cost design for torque overload generator protection. In wind power plants, electrical circuit problems are known to cause short-term torque peaks. In this event, slip clutches protect the costly gearbox against overload by slipping at a defined maximum […]
Precision Torque Limiter with Clamping Hub
R+W torque limiters provide inexpensive insurance with little effect on machine performance. Utilizing a patented preload internal to it’s ball-detent mechanism, R+W torque limiters are all backlash free and highly responsive, with the ability to completely disconnect the drive and driven components in under 3msecs. Disengagement torque can be adjusted in the field, and several […]
