S series helical-worm gear units

The strength of our helical-worm gear units is their simple mechanical structure. This yields a higher efficiency than pure worm gear units. In addition, the S series gear units are quiet during operation.

Helical-worm gear units: simple design, high efficiency

The simple design makes for cost-effectiveness. The individual adjustment of torque and speed allows for space-saving installation of our helical-worm gear units. Use the S series gear units to implement simple tasks in your machine or plant applications.

The combination with a helical gear stage significantly increases the efficiency compared to pure helical-worm gear units. The linear power transmission makes the helical-worm gear units especially quiet in operation. Why? Power is transmitted via the worm shaft and the worm gear to the drive shaft. This dampens the torque impulses and reduces the noise.

The torque ranges from 92 Nm to 4,000 Nm.

Only half the solution without a motor? Then use our modular concept and combine the gear units of the S series with an AC motor to an S..DR.. helical-worm gearmotor, or with a servomotor to an S..CMP servo helical-worm gearmotor of your choice. Or simply choose the separate AC motor or servomotor that meets your requirements.

Your benefits

  • Space-saving installation

    thanks to individual adjustment of torque and speed in all 7 sizes.
  • High efficiency

    due to the helical and worm gear combination. Much higher than in basic helical-worm gear units.
  • Low-noise operation

    because the linear power transmission dampens torque impulses on the input shaft.

Features

  • Significantly more efficient than pure worm gear units due to helical-worm combinations
  • Very low-noise operation
  • Available variants:
    • Foot- or flange-mounted
    • B5 or B14 flange-mounted
    • Solid shaft or hollow shaft
