✅ Bore 2: 1/4" (6.35 mm)
✅ Length: 35 mm (1.38 in)
✅ Outer diameter: 27 mm (1.06 in)
✅ Zero backlash
✅ High torsional rigidity
✅ End-play tolerance and misalignment absorption via bellows
✅ Pack size: 1 piece
💡 What is a bellows-type flexible coupling and what is it used for in precision drive systems? Used to connect motors to shafts in compact setups while absorbing misalignment and vibration. - Absorbs minor misalignment and vibration in precision drives - Handy for CNC machines, robotics, and automation where torque transfer matters - Maintains alignment under load and reduces wear and noise This handy coupling enhances accuracy and helps reduce wear in tight, precision-driven systems.
