| WK SERIES | WS SERIES | WF SERIES |
Our WR series helical gear reducers are based on the building block design, so its convenient for them to fit all types of motors or to connect with other power input, and its possible for different types of machines to combine or connect.
1,Compact construction, saves space for mounting, large load-bearing capacity and long life.
2,High transmission efficiency and low noise. A single machine can reach a transmission efficiency as much as 96%.
3, Precise division of transmission ratio with a wide range. The combination of machines can produce a larger transmission ratio at a low output rotational speed.
4,Specification: WRF146.
5, Input power: 0.12~90KW.
6, Output torque: 960~21700Nm.
7,Transmission ratio: 5.31~21342.
8,Installation: Foot-mounted, B5/B14 flange-mounted, input shaft, hollow output shaft, etc.
