Beam Couplings
14Pages

Beam Couplings Multi-Beam Single-Beam Step-Beam • Torsionally rigid design • Zero backlash • No moving parts • Single beam simple coupling compatible with industry standard types • 3-Beam single stage for increased torsional stiffness • 6-Beam two stage for torsional stiffness and increased radial compliance • Step Beam for low inertia, electrical isolation, low cost Beam couplings will readily accommodate any combination of axial motion, angular and parallel misalignment. The 3 start helical-cut design provides higher torque capability and reduced wind-up compared with single beam versions. Multi-Beam is available in three standard materials: stainless steel, aluminium and acetal, for shaft diameters from 1mm to 38mm.
