Extreme temperature ranges, high pollution levels, high vibration levels, and 24/7/365 operation call for engineered drive components which can take the abuse. Extending component maintenance intervals is a priority, since industrial gearboxes, electric motors, bearings, and drive shafts typically require at least partial disassembly and replacement of wear parts. A new solution involves zero maintenance, […]

Compact stainless steel bellows couplings
The BKS series of stainless steel, welded bellows couplings are up to 1/3 shorter in length, reducing moment of inertia and saving space. Manufactured in Germany, the BKS makes use of 1.4301 (304) stainless steel hubs, precision machined to a high level of concentricity. Laser welded while mounted onto a common shaft to guarantee straightness, […]
Wind Turbine couplings deliver 100,000 Nm of torque
Zero-Max Wind Turbine Couplings are now available as an upgrade replacement for existing wind turbines and for OEM applications. These couplings easily handle torque spikes and high misalignment installations. They have composite disk packs at both ends of a center spacer for strength and generous flexibility. The composite disk packs (flex elements) allow a surplus […]
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 […]
GERWAH Product Line
The GERWAH line of products consists of magnetic couplings, metal bellows couplings, servo-insert couplings, line shafts, RING-flex couplings and safety couplings. These couplings are available in a range of sizes and torque capacities to 3,800 lb-ft. The low mass of the lightweight construction helps increase machine performance and reduce energy costs.

Six factors to remember about couplings in a motion system
Updated May 2019 || Physical values such as torque, torsional rigidity, spring stiffness, moment of inertia, imbalance, and zero-backlash play a major role in coupling design. Here are a few facts to keep in mind when you design your motion system. 1. Torque (Nm) is the product of an acting force and the effective length […]
EZV Series Adjustable Line Shafts from R+W America
A convenient location for manual phase adjustment along a mechanical drive system is now available in the EZV series adjustable line shafts. Making use of a high strength intermediate collar between two telescoping sections of precision tubing, the EZV naturally places the location for phase adjustment in an easily accessible, open space. Due to the […]
High Misalignment, Low Inertia Servo Couplings
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 […]
Innovative Steel Bellows Coupling Released
When first examined, steel bellows couplings seem to be the same superficially, but as one looks at the technical details, they will find there are substantial differences. The construction, structure and manufacturing quality of the steel bellows are the main factors for operational safety, reliability, service lifetime, misalignment capability and functional safety of the entire […]
How to Properly Select a Bellows Coupling
Properly selected bellows couplings result in the best control over the load in any servo application. Here are tips to ensure you choose the right size for the application. Bellows couplings help maintain tight controls over loads. For years, bellows couplings have been a mainstay for efficient motion systems because they offer high torsional stiffness, […]
