Backlash-Free Couplings

Backlash-Free Couplings

Ruland oldham couplings are comprised of two aluminium hubs with drive tenons that mate with a floating center member. This design allows for easy sliding to accommodate misalignment. Oldham couplings have light bearing loads since the only resistance caused by misalignment is frictional. They also have the advantages of electrical isolation. The couplings accommodate angular and axial misalignment, and are useful in applications where parallel misalignment is present. The replaceable center discs are available in two materials, offering different levels of torsional rigidity.

Beam couplings from Ruland have overlapping spiral cuts in a single piece of aluminium. The spiral cuts accommodate angular misalignment, parallel misalignment and axial motion. The one-piece design and cut pattern ensure backlash-free operation and allow for a small amount of shock absorption. Beam couplings are useful when angular or complex misalignment is present. Stainless steel versions are also available for applications requiring higher torque transmission capabilities.

Ruland beam and oldham couplings are offered in a variety of body sizes with bore sizes from 3/32 (2) to 1 1/8 inch (28mm).

The complete line of products includes shaft collars and rigid couplings, and a full line of motion control couplings: beam couplings, bellows couplings, oldham couplings, miniature disc couplings and zero backlash jaw couplings.
