Electronic Components & Devices

Coupling features stainless steel bellow.

BKL Series exhibits high torsional rigidity with zero backlash. Bellow can compensate for axial, angular, and lateral misalignment simultaneously. Moment of inertia is very low due to its low mass and low weight. Shaft hubs are custom bored on each side for shaft sizes from 4 to 62 mm (0.16 to 2.44 in.) with or without keyways. Torque capacities range from 2 to 500 Nm (17 to 4,425 lbs-in.).
