Push Pull Actuators: High-Precision Solutions for Industrial Applications
At UHV Design, our Push Pull Actuators are engineered for high-duty, high-torque, and high-precision linear motion applications in ultra-high vacuum (UHV) and demanding process environments. These magnetically coupled vacuum actuators provide exceptional axial stiffness, high load capacity, and zero vacuum thrust, making them ideal for precise positioning, manipulation, and process control. Our robust, long-life design eliminates vulnerable components such as bellows and dynamic seals, improving reliability, reducing maintenance requirements, and ensuring consistent performance in high-vacuum and high-pressure conditions.
For enhanced versatility, the Push Pull range includes both linear and linear/rotary motion solutions with stroke lengths of up to 300 mm (12 inches). Linear models can be supplied with pneumatic or motorised actuation options, enabling remote operation, automation, and seamless integration into advanced vacuum systems and automated processes. Combined with proven magnetic coupling technology, these features deliver accurate, repeatable motion and dependable long-term performance across a wide range of scientific, research, and industrial vacuum applications.
