The BWC (Bellows Clamp) Series coupling provides a new range of coupling options
with the high torsional stiffness. The higher torsional stiffness provides the benefit of
accuracy and repeatability in motion control applications. The BWC series coupling
features aluminum hubs and corrosion resistant steel bellow.
The compact design also offers the benefit of low inertia. The BWC Series also has a torque capacity of up to 89 in-lbs, with a maximum bore capacity of .748 inches in diameter. The BWC utilizes clamping style hubs that provide easy installation and removal of the coupling. The bellows design also offers up to .016 inches of axial misalignment, with low reactionary loading on bearings.
