Torsionally stiff rigid couplings are best used on shafts that are already in proper alignment, so are well-suited to pump, mixer, drive shafts, and other power transmission applications. Stafford Manufacturing Corp., Wilmington, Mass., offers a full line of rigid couplings in a variety of configurations and sizes for connecting these types of components. Rigid couplings […]
Bellows couplings for printing applications
Ruland, Marlborough, Mass. manufactures bellows couplings with high torsional stiffness that can accommodate all forms of misalignment and are well suited for large format printers, 3D printers, offset printers, web converting equipment, and print finishing equipment. Ruland’s bellows couplings are comprised of two anodized aluminum hubs and a stainless steel bellows, for a lightweight, low […]
High-speed shear spacer protects against torque overloads
The Kop-Flex high-speed shear spacer coupling from Emerson Industrial Automation, Florence, Ky., uses a patented double-tube design, precision machining and bearings, and special metal treatments to help provide predictable shear during torque overloads on turbo drivetrains, allowing safe coast down of systems turning at up to 20,000 rpm. Developed to protect gas-turbine-powered generator drives during electrical […]
Blog gives coupling selection and design advice
A few weeks ago, I blogged about a special traveling educational event, the Realigning America Tour, which is still underway. The event, co-sponsored by Lovejoy Inc. and VibrAlign Inc., features seminars on coupling and alignment issues to help maintenance professionals solve their alignment and coupling issues. But more importantly, this news brought to my attention VibrAlign’s blog […]
Pick the right coupling for each high tech application
Selecting the right coupling for your application is critical to system safety and reliability, says Ruland Manufacturing Co. Inc., Marlborough, Mass., which manufactures a diverse couplings product line while providing technical support and application experience. Ruland’s coupling line includes rigid couplings with precision honed bores and five types of zero-backlash couplings: beam, bellows, disc, jaw, […]
Lovejoy and VibrAlign develop partnership, educational series
Lovejoy Inc., Downers Grove, Ill. and VibrAlign Inc., Richmond, Va., have developed a strategic alliance to create improved educational opportunities for users of couplings and shaft alignment tools. In addition, the two companies are partnering to bring a traveling educational series to several locations in the next two months. Founded in 1900, Lovejoy specializes in […]
Enhanced disc couplings for rotating equipment
Doing some research today, I stumbled upon this still fairly new product from Rexnord—the new Thomas XTSR52 and XTSR71 disc couplings, enhanced lines of the company’s series 52 and 71 couplings. The new designs offer new and improved features optimized for customer installation, maintenance, operation and safety. They also feature higher torque and lower mass, being optimized for […]
Robust jaw couplings make for easy water testing
Testing water samples is an important and critical business, so when Hach Co., Loveland, Colo.—a provider of water quality testing and water quality analysis—was designing one of its signature samplers, it wanted a design that was maintenance free and wouldn’t cause any problems. That’s why Hach turned to R+W America, as it worked on the […]
R+W expands offerings to include flexible disc pack couplings
R+W, which is known for flexible shaft couplings for servodrives, is expanding its offerings to include flexible disc pack couplings. Its new series of Survivor couplings is best suited for demanding industrial power transmission systems. The Bensenville, Ill.-based company has spent more than two decades creating flexible bellows couplings that offer high torsional stiffness, low […]
Elastomeric couplings stabilize hydraulic fracturing pumps
Extracting natural gas from underground shale formations is done via high-pressure pumping equipment that injects a specialized mixture of water, sand and chemical additives into vertical, horizontal or multi-lateral well bores. These high pressures can lead to vibration and other damage to the truck-mounted hydraulic fracturing pump units. A major manufacturer needed reliable couplings for […]
