These oldham couplings are comprised of two aluminum hubs with drive tenons that mate with a floating center member. The design slides easily to accommodate misalignment. These couplings have very light bearing loads since the only resistance caused by misalignment is frictional. They accommodate angular and axial misalignment, but are especially useful in applications where parallel misalignment is present.
The beam couplings have overlapping spiral cuts in a single piece of aluminum. 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 especially suitable when angular or complex misalignment is present. Stainless steel versions are also available for applications requiring higher torque transmission capabilities.
These beam and oldham couplings are offered in a variety of body sizes with bore sizes from 3/32 in. (2 mm) to 1-1/8 in. (28 mm).
