Ruland Manufacturing BS Series set screw bellows couplings have low inertia, making them suitable for applications with speeds up to 10000 rpm. These RoHS 3 & REACH compliant couplings feature a balanced design for reduced vibration at high speeds. They test beyond DIN 912 12.9 standards for maximum torque capability and come with six convolutions to allow high torsional rigidity. These units have bellows that flex while remaining rigid under torsional loads, to accommodate all types of misalignments.
