SDP/SI Bellows Couplings are flexible couplings designed to accommodate various types of load conditions. SDP/SI Hi-Flex Bellows Couplings are used for applications that require large amounts of shaft misalignment combined with low resultant radial loads on the bearings. SDP/SI Modular Bellows Couplings are configurable and provide high torsional rigidity for high-speed torque transmission. A wide […]

SDP/SI Helical Couplings, or beam couplings, are another type of flexible coupling allowing for axial motion, angular misalignment, and parallel offset. This coupling design features one-piece construction resulting in zero backlash. The coupling is made flexible by removing material from the piece in a spiral pattern. SDP/SI Helical Couplings are available in aluminum and stainless […]

The compact […]

The latest designed ALS Couplings from Miki Pulley are available in three different types for more precisely handling parallel, angular, or axial misalignment applications. The key feature of this coupling design is its center element. Each of the three models’ center members has a unique, durable material and shape. Also called a ‘spider’, it is […]

The high-quality original from the world market leader: RINGFEDER Shrink Discs are flange-shaped, friction-locked shaft-hub connections and the more powerful and reliable alternative to conventional shrink fits, wedge, keyway, or polygonal connections. In contrast to internal locking devices, e.g. locking assemblies, the pressure is applied from the outside to the hollow shaft or hub, thus […]

The PROPFLEX coupling is a flexible displacement coupling for different application areas. Torque transmission with simultaneous compensation of displacement occurs through rubber bushes. Through these specially developed rubber bushes, noise-reducing properties are achieved that are clearly superior to those of conventional displacement couplings. Thus the PROPLEX coupling satisfies the most rigorous comfort requirements by isolating […]

Locking down top talent and motivating employees to take advantage of future growth opportunities is more important than ever. Because of contributions made by companies and individuals this year to the PTDA Foundation (the charitable arm of Power Transmission Distributors Association) power transmission/motion control (PT/MC) employers are further empowered in their recruitment and retention efforts […]

The pump and drive system-OEMs team up through their IoT-platforms for enhanced pump operations Sulzer and Siemens Large Drives Applications (LDA) are using their collective expertise to provide operators of large centrifugal pumps with an enhanced digital value proposition: Bringing together their respective IoT-platforms and services, BLUE BOX™ and SIDRIVE IQ, the two companies are […]

For reliable and backlash-free torque transmission The RIGIFLEX-N steel laminae couplings are used wherever reliable and backlash-free torque transmission with simultaneous shaft displacement is required. The steel laminas are designed as layered, waisted laminae sets. They are connected fully backlash-free with hubs and flanges via positive-locking dowel screws.

You know ROTEX as a versatile and reliable elastomer coupling. Now you have the chance to get to know new sides of the globally top-selling shaft coupling: The ROTEX goes digital. It measures torque and speed, shows the values on a display, and transmits the measuring results wirelessly to your smartphone or PC. This will […]

Force Control Industries’ full lineup of MagnaShear™, Posistop, and Positorq motor brakes and Posidyne™ clutch brakes in washdown configurations for food processing and other applications will be featured in EASA Booth #1024. While all oil shear products, by design, are totally enclosed in a heavy cast housing, the washdown option provides additional protection from moisture, […]

The PTDA Foundation is seeking nominations for its Wendy B. McDonald Woman of the Year Award and Robert (Bob) K. Callahan Advancing Leaders Award. The Wendy B. McDonald Woman of the Year Award recognizes a woman who, regardless of where she is in her career, brought change as an integral contributor to the success of […]

The Power Transmission Distributors Association (PTDA) will convene for the PTDA 2023 Canadian Conference in Ottawa, Ontario, Canada June 6–8. Delegates in the power transmission/motion control (PT/MC) industry, representing PTDA distributor and manufacturer companies, will be in attendance to broaden cross-channel networks, expand connections and deepen business relationships. “We’re proud of the relationships our U.S. […]

Ruland has expanded its range of short rigid couplings to include keyways and step bore sizes. This expansion gives designers a wider variety of standard short rigid coupling options for applications with space or weight restrictions or where designers prefer a simplified assembly with fewer screws than traditional rigid couplings. Many servo-driven applications in industries […]

A shaft collar is a small, simple component. Today’s bore shaft collars are designed with bore protection and longevity in mind. The problems traditionally associated with bore shaft collars, like equipment damage, are minimized through modern design. Bore shaft collars help hold certain components of machinery in place and even serve as mechanical stops. Our […]

By Shelley Doherty Shaft collars attach to shafts and other pieces of hardware to affix components in place. They can grip bearings in the right position, act as mechanical stops to halt rotary motion along the shaft, and ensure internal components don’t shift into misalignment. Because these components are so versatile, they come in a […]
