Features

  • High Continuous Torque Output: Delivers up to 25 Nm of continuous torque and 44 Nm for acceleration, ideal for demanding motion control and automation systems.
  • Durable Steel Construction: Equipped with a robust steel ring gear and needle-bearing planetary wheels for long-lasting, low-backlash performance.
  • Broad Reduction Ratio Range: Supports reduction ratios from 3:1 to 120:1 across 1-, 2-, and 3-stage designs, offering exceptional speed and torque flexibility.
  • High Efficiency Performance: Achieves mechanical efficiency up to 97% in single-stage configurations—reducing energy loss in continuous operation.
  • Long Service Life and Low Maintenance: Factory-lubricated for life with up to 20,000 hours of service—engineered for maintenance-free reliability in harsh environments.
  • Compact and Load-Tolerant Design: Compact housing handles axial loads up to 130 N and radial loads up to 390 N, supported by dual ball bearings on the output shaft.
