Deskripsi
Worm shaft
Type: Worm shaft (gear transmission component)
Model: Typically embedded in RS Series, Z120+RS, and JD Series actuators
MFR : JINDA ACTUATOR
Product Overview:
The worm shaft is a precision-machined mechanical component that forms the heart of the gear reduction system in multi-turn and quarter-turn electric actuators manufactured by Tianjin Jinda Actuator Co., Ltd. It converts motor rotation into controlled torque for valve operation, offering high reduction ratios and self-locking capability.
