NW Series Three-Ring Reducer

FEATURES:

1. Large rotation ratio and compact structure

Single stage speed ratio 11-99, two pole speed ratio 30-594, two pole three ring 594-9801

2. High reliability

Three ring drive adopts power split, which has good overload performance and low tooth failure probability.

3. High efficiency and low temperature

When the speed ratio is large, the three ring single stage is equivalent to the multi-stage rotation of other types of reducer.

4. Simple structure and good maintenance performance

5. Long life，Low noise
