Malfunctions happen. And when they do, damage and repair costs follow. Safety couplings are the mechanical connecting elements designed to protect other machine components surrounding a drive system. When a malfunction occurs, safety couplings help keep the damage to a minimum. Safety couplings include torque limiters to handle mechanical overload. In disconnect types, torque limiters […]

New R+W safety coupling handbook now includes the heavy-duty ST series
R+W Coupling Technology has released a new and updated version of its “Safety and Overload Couplings” educational handbook, which now includes the heavy-duty ST torque limiter series. These ST torque limiters are suitable for industrial drive applications with potential for overload, offering disengagement torques from anywhere between 200 and 165,000 Nm. This handbook covers all […]
Couplings make the big-time
Who knew that something so small could make such a big difference in complex applications? We did, that’s who. Couplings—from bellows to jaw and Oldham to disc—are used in almost every motion control application to manage misalignment while transmitting torque from one shaft to another. They are often considered a commodity product but are too […]
A look at coupling selection tools
I often think of how the Internet has changed our lives, and how it has made it so much simpler in many ways. For example, buying a rare item meant either hoping your local store had it in stock or paging through catalogs. Going on a trip used to mean highlighting a route on a […]
Compact safety coupling
Making use of the existing BKC line of compact bellows couplings, the SL2 safety coupling is a compact, flexible and torsionally rigid option with integral torque overload release. Designed for aggressive servo driven applications, it is completely backlash free, relying on preloads and frictional connections, along with a hydroformed stainless steel bellows to relieve bearing […]
Two-Year Project Produces Safety Coupling 60-70% Lighter
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 […]
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 […]
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 […]
Servo Coupling Handles 2.9x More Lateral Misalignment
The trend in industry to process more material faster and more efficiently calls for a high-torque, high-misalignment, low-inertia servo coupling, with minimal compromise to torsional stiffness. Stainless-steel bellows couplings have the highest torsional stiffness of commercially available flexible couplings, making them the best choice for aggressive servo-driven applications. But in cases where the two shafts […]
Stainless Steel Servo Insert Coupings
Bensenville, IL – Stainless steel SERVOMAX couplings from R+W feature a highly chemically resistant elastomer element that is press fit between two precision machined coupling halves, giving it zero backlash and guaranteed concentricity. The inserts, available in four different Shore hardnesses, depending on the damping and torque rigidity required, are heat treated within the precision […]
