Backlash-Free Couplings

Ruland oldham couplings are comprised of two aluminium hubs with drive tenonsthat mate with a floating center member. This design allows for easy sliding toaccommodate misalignment. Oldham couplings have light bearing loads since theonly resistance caused by misalignment is frictional. They also have theadvantages of electrical isolation. The couplings accommodate angular and axialmisalignment, and are useful in applications where parallel misalignment ispresent. The replaceable center discs are available in two materials, offeringdifferent levels of torsional rigidity.

Beam couplings from Ruland have overlapping spiral cuts in a singlepiece of aluminium. The spiral cuts accommodate angular misalignment, parallelmisalignment and axial motion. The one-piece design and cut pattern ensurebacklash-free operation and allow for a small amount of shock absorption. Beamcouplings are useful when angular or complex misalignment is present. Stainlesssteel versions are also available for applications requiring higher torquetransmission capabilities.

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

The complete line of products includes shaft collars and rigidcouplings, and a full line of motion control couplings: beam couplings, bellowscouplings, oldham couplings, miniature disc couplings and zero backlash jawcouplings.
