GGM

Offering a wide range
20 kinds of wide range from 3 up to 180 gear ratio is supplied. You can choose optimum gear ratio like parallel gearhead.Max allowable torque is same as parallel gearhead.

Costs Saving
BRH gearhead contributes components cost saving, assembly process number saving by removing connected components.

Example

- Install as following picture according to shaft shape.

- When installing load shaft to hollow shaft, adjust center of hollow shaft and load shaft.

- There is key way in hollow shaft Also there is key way in load shaft and fix with key.

- H7 is recommended as load shaft tolerance.

- In case of high impact by frequent instant stop and high overhung load, Short load shaft is recommended.
