BWLC Series - Bellows Clamp Style Couplings - Metric Bores
Bellows Style Couplings (BWC & BWLC Series)
-
The BWLC (Bellows Clamp) Series coupling specifically addresses higher
torque and bore capacities in the area of motion control. The BWLC Series
offers the highest amount of torsional stiffness for accuracy and repeatability.
The BWLC Series coupling features a corrosion resistant steel bellow and
aluminum or steel hubs.
The BWLC Series also has a torque capacity of up to 1,328 in-lbs, with a maximum bore capacity of 1.574 inches in diameter. The larger size of the BWLC allows for a greater amount of axial misalignment of .020 inches, with low reactionary loading on bearings.
