Oldham couplings are typically used in motion control applications where zero-backlash performance is required. However, these couplings are increasingly used as an alternative to straight jaw couplings on general industrial equipment such as pumps, valves, gearboxes, and conveyor systems due to their versatility, ease of assembly, and extended life if misalignment is present. The oldham […]
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 […]
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 […]
Zero Maintenance Bearings– New Option For Schmidt Offset Couplings
Zero maintenance bearings are now available as an option for Schmidt Offset couplings from Zero-Max. This new coupling feature eliminates periodic coupling lubrication and the resulting system downtime. Schmidt Offset couplings deliver precision for parallel offset shafts. They transmit constant angular velocity and torque in a range of parallel shaft misalignments. They are used in […]
Explosion proof couplings
Flexible couplings are a critical component for applications involving potentially explosive materials found in automotive paint and cleaning stations, chemical plants, and powder mixing areas. A lack of radially flexible elements in shaft linkage can result in high radial loads on shaft bearings, eventually leading to heat generation and bearing failure, making flexible shaft couplings […]
