CNC Machined Stepped Electric Actuator Rear Shaft
We specialize in manufacturing electric actuator rear shafts used in applications such as power window systems, electric seating mechanisms, and industrial automation equipment. This component is a precision-machined stepped shaft specifically designed for electric actuator systems, functioning as a rear shaft or transmission connection element.
Featuring multiple stepped diameters, the shaft supports accurate alignment within linear motion assemblies and contributes to overall structural stability during operation. Manufactured with high dimensional precision and durability, this actuator shaft can be customized according to customer drawings and supports both prototyping and mass production requirements.
Manufacturing & Customization Capability
This type of stepped shaft for electric actuators is manufactured using CNC turning operations, with key control placed on concentricity and dimensional stability across multiple stepped sections. Accurate coaxial alignment is critical for reducing vibration and maintaining stable operation in electric actuator systems and linear motion mechanisms.
Through CNC machining, we are capable of processing a wide range of materials, including carbon steel, stainless steel, and aluminum, while ensuring consistent dimensional accuracy and surface finish. Supported by a well-established quality control process and flexible delivery capabilities, we are able to supply parts for both domestic and international markets, assisting customers in moving efficiently from development to mass production.
We provide services including quotation, drawing review, prototyping, and small-batch trial production. As a manufacturing partner focused on electric actuator components, we support customers throughout the evaluation and production stages. Customers are welcome to contact us and provide drawings or specifications for technical assessment and quotation.
Industry Applications
