Click2Contact

The Faulhaber 20/1R stainless steel planetary gearhead has a diameter of 20 mm. It can achieve continuous torque of 800 mNm, or up to 1100 mNm for short periods during interval operation. The input speed can be as high as 12,000 rpm and the product can be combined with DC, brushless and stepper motors with a diameter of 17 to 22 mm.

The output shaft of the 20/1R has no axial play due to the pretensioned ball bearing. The gearhead is available with one to five stages, and the span of the 16 possible reduction gear ratios ranges from 3.71:1 to 1526:1. There is also a choice between the normal temperature range of ‐10°C to +125°C and a low-temperature variant with ‐45°C to +100°C. The typical temperature range for planetary gearheads made from metal is therefore extended considerably.

Numerous product variants, including an autoclavable version, makes it easy to adapt to completely different applications. The connection of the 20/1R planetary gearhead is compatible with its predecessor, the 20/1. When upgrading, the previous gearhead can be replaced with the later model without further changes.
