EAST AI
Product Description
Single Rod Plunger Cylinder is a hydraulic actuator featuring a solid plunger instead of a conventional piston. Designed for simplicity and efficiency, it delivers linear motion through direct fluid pressure on the plunger’s base.
Unlike piston-type cylinders, it does not contain internal seals between bore and piston, allowing higher pressure resistance and better performance in short stroke operations. This makes it an ideal solution for lifting, pushing, or pressing functions where space is limited.
The Single Rod Hydraulic Plunger Cylinder is commonly used in presses, injection molding machines, lifting tables, and agricultural equipment. When equipped with a built-in spring return mechanism, it also serves as a Spring Return Plunger Cylinder Single Rod, enabling quick retraction without hydraulic power.
