40mm By 55mm Aluminum Flexible Shaft Coupling With 15 To 20mm Bore Zero Backlash High Torque Plum Elastomer For 3D Printers CNC Machines And Servo Stepper Motors
✔️ 40x55mm aluminum housing, 15-20mm bore, single-piece, zero-backlash, high torque
This 40x55mm aluminum flexible shaft coupling connects motors to shafts in compact builds like 3D printers, CNC machines, and servo/stepper systems. It uses a plum blossom elastomer to absorb vibration, resist oil, insulate electrically, and operate from -20 to 80 C. The zero-backlash design ensures precise torque transfer under light loads.
✅ Size: 40 mm diameter, 55 mm length; bore 15-20 mm
✅ Material: aluminum body with plum elastomer insert
✅ Zero-backlash torque transmission under low torque conditions
✅ Torque capacity exceeds traditional claw couplings by over 2x
✅ Oil resistance and electrical insulation; operating -20 to 80 C
💡 What is a flexible shaft coupling used for in hobby CNC machines and 3D printers?
A handy explanation of why folks pick these couplings for precise torque transfer and vibration damping.
- Absorbs vibration and compensates for minor misalignment in compact setups
- Delivers reliable torque transfer with low backlash across small drives
- Durable aluminum housing and plum elastomer resist oil and heat (-20 to 80 C)
- Fits 15-20 mm bore shafts common in printers and CNC gearboxes
