Upgrade D20*L25 Flexible Shaft Coupling 5mm to 5mm Aluminium Plum Connector Flexible Coupler for 3D Printer CNC Machine and Servo Stepped Motor

The plum blossom coupling is closely combined with the main body of the two half coupling with polyurethane plastic as the elastic element, and the main body is mainly made of alloy aluminum. It is applicable to servo system, spindle drive, lifting platform, machine tool drive and gearbox motor. Compact, no backlash, which can absorb vibration and compensate radial and angular deviation. It is mainly suitable for working places with frequent starting, forward and reverse rotation, medium-high speed, medium torq.

• Size:D20mm*L25mm , Bore:5mm to 5mm
• The elastic spacer is made of polyurethane, and the torque exceeds the traditional claw coupling by more than 2 times
• During transmission, it can realize zero backlash torque transmission torque under low torque state
• Plum blossom elastomer can resist oil and electrical insulation, operating temperature: -20℃~80℃
• Excellent elastic effect to absorb vibration, eccentricity and deflection
