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 […]
