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 […]
Miniature Beam Couplings for Micro Component Applications
Marlborough, MA – For micro component applications, Ruland now offers miniature beam couplings. Available with outer diameters of 9.5 and 12.7 mm and bore diameters of 3 mm, the couplings are made from a single piece of aluminum or stainless steel with overlapping spiral cuts. Ruland’s P-series beam couplings are made from aluminum and cover […]
International Collars
The International Series series of one- and two-piece clamp-style shaft collars suit retrofits and new equipment for a global market. They feature inch or metric bores, DIN 12.9 socket headed cap screws, high grade materials and finishes, and an attractive and practical form. The use of metric screws with inch bores is especially useful when […]
Improved Clamp Design for Flexible Beam Couplings
Marlborough, MA – Ruland Manufacturing Company has introduced a new clamp design for its zero-backlash flexible beam couplings. The couplings now clamp with a single screw on each end, which eases installation, and are balanced for increased rpm capability. The beam couplings now feature both a radial and cross-cut to enhance surface contact with the […]
High Performance from Miniature Disc Couplings
Marlborough, MA – Ruland offers miniature disc couplings both in single and double disc styles. Disc couplings are high performance motion control couplings with zero-backlash, excellent speed capabilities up to 10,000 rpm, strength and torsional stiffness characteristics, as well as low inertia for today’s highly responsive systems. Disc couplings are often used in servomotor and […]
