Racaw Ltd., a designer, and manufacturer of precision positioning components and systems, required reliable shaft couplings for use on its lines of linear and rotary positioning stages. The stages allow precise linear and rotary positioning of objects via a stepping or servo motor with rotary encoder control. A precision worm and wheel (rotary stage) or […]

How to deal with a 42-year-old grid coupling on a steam yacht gondola
In 1980, Great Britain’s National Trust recommissioned Gondola, an 1859 steam-powered vessel for 86 passengers styled after a Venetian gondola, on Coniston Water in Cumbria, England. The 86 ft. long vessel is powered by a twin cylinder, ‘V-90’ configured double-acting steam engine that generates a maximum torque of 8,000 Nm (5,900 lb.ft.) with a service […]
PTDA: A tale of three integrations
Mergers and acquisitions are on the rise across all industries and the PT/MC marketplace is no exception. Not even a global pandemic could sideline M&A activity. Economies of scale and scope, increased market share, tapping into new markets and fresh talent — all can bring great rewards. But what obstacles do companies anticipate? How do […]
The top 5 Coupling Tips articles of 2022
2023 is off and running, but before we dive headlong into all the content we’re excited to bring you in the new year, we want to give 2022 a proper send-off. Here’s a recap of the 5 articles that most captured your attention on Coupling Tips this year. 5. JP Bouchard and Randy Disharoon at the […]
Accommodating bore configurations for your shaft collar or coupling
By Shelley Doherty Stafford Manufacturing Corp. designs and manufactures rigid couplings, shaft collars, and specialty mechanical parts used in automation, power transmission, motion control, and other OEM and MRO applications. The company has collars and couplings available in square, threaded, hexagonal, keyed, and round bore configurations. In addition, it can add drive slots, press-fits, pulleys, […]
Ringfeder’s rugged EPC multiple disc electric pulley clutch
Gasoline engines, pumps, generators, and other machines operating in rugged environments require long-lasting components to ensure successful performance. Clutches designed with durable materials can prevent breakdowns, which would otherwise lead to expensive maintenance and downtime. One example of a ruggedized clutch — the EPC multiple-disc electric pulley clutch — consists of a standard electromagnetic multiple-disc […]
ROTEX ZRS torsionally flexible intermediate shaft coupling with SPLIT hubs or half shell hubs
ROTEX ZRS jaw coupling for bridging smaller and larger shaft distances The lightweight type ZRS made of high-strength aluminum impresses by very high overall stiffness. The high stiffness of the aluminum pipe results from the design; here two pipes combined via webs – the ROTEX cams – are concerned. There is a positive impact on the […]
Locking assemblies in energy efficient high-volume, low-speed (HVLS) fans
HVLS (high-volume, low-speed) fans are generally ceiling-mounted and are less often of the wall-mounted type. They are more than 7-ft (2.1 m) in diameter. Their functional principle relies on size and not on speed to move a large amount of air. Though HVLS fans are used in a wide variety of applications, they are predominantly […]
New high-performance spider for backlash-free servo coupling from KTR
KTR has a new spider in its product range which decisively increases the performance level of the backlash-free servo couplings type ROTEX GS with regard to temperature resistance and pressure resistance. The material is a newly developed “thermoplastic polyurethane” with a hardness degree of “52 Shore D” and a temperature resistance of up to 120° […]
Couplings: electrodeposited bellows from MW Components
These couplings have a distinct bellows shape with convolutions. They are produced using the electrodepositing process, which involves creating a component by adding thin metal layers to a mandrel and then chemically removing the mandrel. MW Components www.mwcomponents.com
