Product Details

Using new lightweight materials and an optimized design, a 30% reduction in weight has been achieved without reducing the torque rating of the gear unit or significant changes to the interface dimensions. This weight reduction, combined with the CSG\'s high torque ratings, results in an exceptional “Torque Density” making it ideally suited for many applications including…

Industrial Robots – allowing operation with higher acceleration rates and payload capacity

Mobile Robots – allowing lower weight designs which improves battery life without sacrificing performance

CSG series harmonic drive™ gearheads, which are improved versions of the CSF series, are designed for high-torque operation. Based on the development concepts of upgrading the load capacity, strength reliability and extending the service life, CSG series has been improved further in respect to the following performance characteristics as compared to CSF series products of the same size.

  • Rated torque improved 30%
  • Repeated Peak torque improved 30%
  • Max. momentary torque improved 30%
  • Ratcheting torque improved 30%
  • Rated service life extended 42% (to 10,000 hours)
  • In respect to external dimensions, rigidity, angle transmission accuracy, input moment of inertia, etc., CSG series Gearheads products are the same as CSF series gearheads.
  • Ratios: 50:1, 80:1, 100:1, 120:1, 160:1
