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, […]

VULKAN Couplings unveils New Integrated Shaft Coupling Design
VULKAN Couplings (www.vulkan.com) has unveiled a new innovation of the Rato DS coupling that is directly connected to a composite shaft. Aside from being a torsional coupling, the combination of high radial stiffness and low bending and axial stiffness makes the Rato DS ideal to work as an integrated misalignment coupling when it is rigidly […]
Flex element insulates couplings and protects from reaction loads
Motion system designers have a new option to arrest electrical current. Zero-Max CD® couplings have composite flex elements that are non-conductive in addition to their primary function. In addition to protecting from stray electrical current, CD couplings protect generators in a system from transferring lower reaction loads to the generator bearings. The coupling’s composite discs […]
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 […]
Backlash-free couplings for high-tech applications
Ruland manufactures a variety of components including oldham couplings and beam couplings. While both coupling types are backlash-free and feature misalignment capabilities, small performance differences make the choice of coupling critical depending on application parameters.
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 […]
Couplings reduce thermal transfer
ServoClass® Couplings from Zero-Max reduce heat transfer from servo motors to driven shafts, reducing heat transfer and variations in system accuracy caused by thermal expansion. It features stainless steel discs designed into the center of the coupling that dissipate heat generated from a connected servo motor. These couplings also provide high torsional stiffness, zero backlash […]
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 […]
