R+W’s BKL Couplings are precision-engineered metal bellows couplings designed for high-performance applications. These couplings feature a single ISO 4762 radial clamping screw per hub, ensuring a secure and backlash-free connection. They are known for their flexibility, torsional rigidity, and ability to compensate for lateral, axial, and angular misalignments, making them ideal for various industrial uses.
