Bellow Couplings are constructed of two aluminium/steel hubs connected to a flexible metal bellows. Bellow coupling torsional rigidity are greater than the disc couplings. The flexibility of the bellows accommodates all misalignment types and bearing loads are low and constant throughout all points of rotation. With aluminum hubs, the bellows coupling has very low inertia ratings, which save the system from unnecessary force and provide even greater response. Running speed capability is on par with the disc couplings at about 10,000 rpm, but can be balanced even for High speed applications.

  • Max Speed: 4,500 RPM
  • Good misalignment capabilities; excellent parallel misalignment
  • Good torsional rigidity with acetal center disc
  • Little vibration dampening
  • Low to moderate inertia


The oldham coupling has the ability to accommodate a high level of parallel misalignment, since the center disc is made to slide over the tenons of the hubs. This lack of resistance (other couplings have a spring-like resistance to misalignment) results in low, and stable bearing loads. The second advantage is the ability to interchange the center disc. Generally, two types of material are used, acetal to provide torsional stiffness and nylon to provide dampening, much like the jaw coupling. Furthermore, the oldham coupling has the unique ability to act as a mechanical fuse. The tenons of the hubs will not interlock if the center disc fails and torque will cease to be transmitted. The oldham coupling’s aluminum hubs help to keep the inertia low.

While the oldham coupling works very well for parallel misalignment, it can only handle small amounts of angular misalignment and axial motion. Too much angular misalignment will cause the coupling to lose its constant velocity characteristic and the coupling will literally fall apart with too much axial movement. Also, while nylon material may be chosen to dampen vibrations, due to the sliding of the hubs and extremely soft characteristics of the nylon used, the coupling is not tight enough to be zero backlash. Speed capability for all oldham couplings is also relatively limited, around 4500 rpm. Additionally, the sliding of the tenons will eventually wear down the insert and replacement will be required

Disc Couplings are available in 2 models Double Disc and Single Disc type. Disc Couplings are composed of either two hus combines with one Disc pack or three hubs combined with two Disc packs.

Both variations of the disc coupling are torsionally rigid. The discs are flexible and allow an ample amount of misalignment, especially in the double disc design. Bearing loads and inertia are low as well. Furthermore, the disc coupling can handle upwards of 10,000 rpm, with low inertia due to the light materials used.
