Stainless-Steel Beam Couplings

Flexbeam couplings now use Type-303 stainless steel.
June 2, 2005

Mechanical performance is comparable to other widely used stainless steels, such as 17-4 ph, but nonmagnetic properties are useful for magnetic-sensitive instrumentation such as magnetometers. Stainless-steel beam couplings offer superior torque and wind-up performance, though with higher inertia than their aluminum counterparts. A one-piece design and spiral cut pattern accommodate angular and parallel misalignment and axial motion, and ensure zero backlash and minimal wind-up. Flexbeam-2 couplings have excellent torque capabilities for precision components such as encoders and tachometers. Flexbeam-3 couplings are ideal for light-duty power transmission applications such as coupling servomotors to lead screws. Twenty different body sizes range from 10 to 38-mm OD and 2 to 19-mm bore.
