Ruland manufactures zero-backlash Oldham couplings that accommodate high amounts of parallel misalignment with low bearing loads and are designed for reduced vibration at higher speeds. The three-piece design allows for in-place servicing without machine disassembly, a useful feature for removing or changing out rollers. Ruland oldham couplings consist of two hubs that mate to a […]

Rigid couplings for packaging applications
Ruland offers rigid couplings that are designed for packaging applications. They have precision honed bores, anti-vibration hardware, and opposing hardware on two-piece styles to ensure superior fit, alignment, and holding power. Rigid couplings from Ruland are available in a wide variety of sizes, styles, and materials to suit the needs of packaging applications such as […]
Beam couplings for encoder feedback systems
P and MW Series beam couplings from Ruland Manufacturing Co. Inc., Marlborough, Mass., are designed specifically for encoder feedback systems. They offer high misalignment capabilities with low bearing loads. Machined from a single piece of aluminum or stainless steel, these couplings feature two sets of two spiral cuts for increased torsional rigidity, accuracy, and repeatability […]
Zero Backlash Jaw Couplings from Ruland
Ruland offers zero backlash jaw couplings for the demanding requirements of start and stop machine vision systems used in industries such as semiconductor, medical, solar, and packaging. The dampening characteristics of Ruland’s jaw couplings reduce settling time and shock loads, making them ideal for these environments. Jaw couplings are a three piece design comprised of […]
Miniature couplings for medical applications
These miniature rigid couplings handle a variety of medical device applications, including test and measurement systems, imaging, patient positioning, and liquid handling such as chromatography. Rigid couplings are zero-backlash, torsionally stiff, and have high torque capacity. They should be used when shaft misalignment is neither present nor desired, with the rigid coupling often used to […]
Oldham couplings: Not just for motion control applications
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 […]
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.
Ruland and Belden Start Joint Venture in Germany
Ruland Manufacturing Co. Inc. and Belden Inc. have started a joint venture in Europe. The company, PTMotion GmbH, has been operational since September 2009, and is headquartered in Berlin, Germany. The new company is headed by Managing Director Ralf Gabriel, a long-time sales engineer for Belden in Germany. He is assisted by Sales Engineer Sebastian […]
New Jaw Couplings Have Zero Backlash
Zero backlash jaw couplings that are three piece couplings comprised of two hubs and a plastic element are one of Ruland Manufacturing’s new products in their coupling line. The Spider, shown below, made of an advanced polyurethane material, provides dampening of impulse loads, minimizing shock to the motor and other sensitive equipment. Available in two […]
Miniature Rigid Couplings Bore Size Down to 3mm
Ruland now offers miniature rigid couplings with bore sizes as small as 3 mm. Miniature rigid couplings are suitable for micro component applications where misalignment is neither present nor desired, including connecting line-shafts, attaching a motor to a gearbox, and servo applications. Offering high torque capacity, stiffness and zero backlash, Ruland’s rigid couplings are increasingly […]
