Deskripsi
Worm Gear
Type: Worm Gear (gear segment or full gear assembly)
Model: Typically embedded in RS Series, Z120+RS, and JD Series actuators
MFR : JINDA ACTUATOR
Steel wheel core, tin phosphor bronze rim casting process, The perfect combination of copper and steel, higher strength and better wear resistance
Product Overview:
The worm gear is a precision-machined gear segment used in multi-turn and quarter-turn electric actuators from Tianjin Jinda Actuator Co., Ltd. It works in tandem with a worm shaft to provide high torque output, compact gear reduction, and self-locking behavior—ideal for industrial valve control.
Specifications:
