Lovejoy Inc. offers two different size ranges in the Bellows coupling product line: the BWC and BWLC series. The BWC coupling offers bore ranges of 1/8” to 3/4” and torque ratings of 3.5 to 89 in-lbs. The BWLC coupling offers bore ranges 1/4” to over 1-1/2” and torque ratings of 159 to 1,328 in-lbs. Both of these designs offer higher torsional stiffness than beam coupling designs and still retain zero backlash. This combination is ideal for precision soldering equipment, pick & place machines, and measurement equipment. The wide range of bore sizes and torque capacities allow for flexibility in selecting the right size coupling for the application.
