1. Key parameters
Parameter values/characteristics
Shaft hole range 15mm (customizable 12-20mm)
Outer diameter/length 56mm/58mm (typical size)
Rated torque 120-150Nm (static)
Maximum speed 4000-6000rpm (after dynamic balancing)
Elastic material polyurethane (optional chloroprene rubber/NBR oil resistant type)
Allowable deviation: radial ± 0.2mm, angular ± 1 °
2. Core Features
High elasticity: The spiral groove design absorbs impact and vibration, protecting the motor and load.

Zero backlash: Precision machining ensures transmission accuracy (<0.1 °), suitable for servo systems.

Maintenance free: No lubrication requirement, easy replacement of elastic body (no need to disassemble the shaft).

Lightweight: Aluminum alloy body (optional stainless steel), weighing only 0.5-0.8kg.

3. Typical applications
Industrial automation: robotic arm joints, CNC feed axes (such as Yaskawa servo motors).

Packaging machinery: driven by filling line conveyor belt (resistant to frequent start stop impact).

New energy equipment: Lithium battery winding machine (optional anti-static design).

4. Installation precautions
Alignment requirement: Laser alignment instrument calibration (deviation ≤ 0.1mm).

Clamping force: Use a torque wrench to tighten the bolt (usually 25-30Nm).

Elastic body installation: Avoid excessive compression (deformation<5%).
