The BKL-DOUBLEFLEX allows for a multiplication of lateral misalignment tolerance by taking advantage of the greater flexibility in the angular direction of each bellows. Compared to its single-flex counterparts, the BKL-DOUBLEFLEX allows for up to 5 times more lateral misalignment depending on the size. Compared to other types of dual-flexture couplings, this new series possesses a very high level of torsional stiffness with zero backlash, and a low moment of inertia, making it ideal for servo drives in packaging equipment and special machinery.
The BKL-DOUBLEFLEX series is currently available in torque ratings from 15 ‚â€“ 500 Nm (132‚â€“ 4425 in-lbs.) and can accept English or metric shafts from 8 ‚â€“ 62 mm (5/16″ ‚â€“ 2-5/16″ in.). Special miniature versions are also available for troublesome encoder coupling installations.
