Bellows Couplings suit high rpm applications.

Intended for motion control applications, Bellows Couplings feature balanced design with stainless steel bellows and aluminum hubs. Parallel misalignment, angular misalignment, and axial motion are accommodated by bellows. Since couplings have no moving parts and zero backlash, maintenance-free life is assured. Six outside diameters range from 19/32-2 in. in set screw style and Nomar clamp style....

Rigid Couplings suit motion control applications.

Offered in aluminum, black oxide carbon steel, and stainless steel, 1- and 2-piece Rigid Couplings come in straight and step bore combinations to fit shaft sizes from 1/8-2 in. and 3-50 mm. Featuring precision-honed bores, couplings are torsionally rigid with virtually zero windup under torque loads, but are also rigid under loads caused by misalignment. Screws have Nypatch treatment to prevent...
