NBK Japan MBB-40C 16mm to 22mm Bellows-type Flexible Coupling, Zero-Backlash Bellows Flexible Shaft Coupling for Servo and Stepper Motors

NBK Japan MBB-40C Bellows-Type Zero-Backlash Flexible Coupling for Servo and Stepper Motors, 16-22 mm Bore, 40 mm OD, 51 mm Length
✔️ Zero-backlash bellows coupling for precise servo/stepper drive; accommodates 16-22 mm shafts; 40 mm OD and 51 mm length; high torsional rigidity; Made in Japan

NBK Japan MBB-40C is a bellows-type flexible coupling designed to connect servo and stepper motors. It provides zero backlash torque transfer and high torsional rigidity while absorbing angular misalignment, eccentricity, and end-play. This compact 16-22 mm bore coupling (40 mm outer diameter, 51 mm length) is ideal for precise motion control in CNC machines, 3D printers, robotics, automation, and lab equipment. Pack size: 1 piece. Made in Japan.
✅ Bore sizes: 16 mm to 22 mm (0.63 in to 0.87 in)
✅ Outer diameter: 40 mm (1.57 in); Length: 51 mm (2.01 in)
✅ Zero-backlash design with high torsional rigidity
✅ Bellows-type element absorbs angular misalignment and end-play

💡 What is a bellows-type flexible coupling used for? These couplings are handy for linking motor shafts in systems where misalignment or end-play would hurt performance. - Absorbs angular and parallel misalignment for smooth motion - Maintains zero backlash for repeatable positioning - High torsional rigidity for reliable torque transfer - Easy to install with standard bore sizes This handy coupling boosts position accuracy and smooth operation in automation, CNC machines, 3D printers, and robotics.
