Mechanical Product: Flexible Servocouplings

BK8 couplings compensate for angular, axial, and lateral misalignment with stainless-steel bellows.

The bellows preserve torsional stiffness for high-precision, zerobacklash servo applications requiring a compact design with a low moment of inertia.

The couplings fit shafts 12 to 80 mm in diameter and are rated for torques between 15 and 1,500 N-m. Torques up to 10,000 N-m and nontraditional hub styles can be accommodated upon request.
