SDM Ball Screw Linear Actuator FAQ
What is the SDM Series ball screw linear actuator?
The SDM Series is a ball screw linear actuator for stable positioning, high repeatability and high-load linear motion in general industrial automation environments.
When should I choose SDM instead of a belt driven actuator?
Choose SDM when the equipment requires higher positioning accuracy, better rigidity, stronger thrust or vertical movement. A belt driven actuator is more suitable for high-speed long-stroke transfer.
Is SDM suitable for vertical axis applications?
Yes. The ball screw drive structure gives SDM better load holding and thrust capability, making it suitable for vertical positioning, lifting and precision assembly tasks when properly sized.
What is the maximum speed of the SDM Series ball screw linear actuat...
The maximum speed of the standard SDM Series ball screw linear actuator is typically up to 1,000 mm/s. For higher-speed requirements, please contact SAHO engineers to confirm whether a customized solution is available.
How do I select the correct SDM model?
Choose the model based on payload, stroke, speed, required repeatability, mounting direction, motor size and whether external guide support or multi-axis integration is needed.
What maintenance does the SDM Series require?
Regular inspection of lubrication, screw condition, guide rail movement, coupling alignment and operating noise helps maintain stable positioning accuracy and extend service life.
SDM Ball Screw Linear Actuator Applications
SDM ball screw linear actuators and screw type linear actuator modules are used in precision assembly, laser processing, inspection equipment, medical automation, lithium battery production, electronic component assembly, automotive equipment and solar cell handling.
