Hydraulic Cushion Cylinder for Press Machine
The hydraulic cushion cylinder protects the cylinder and reduces the impact in the press. When the piston is at the end of the stroke, the hydraulic cushion cylinder can slow down its movement to avoid strong mechanical collisions and noise. This can not only protect the cylinder and related components from damage, but also improve the working accuracy and stability of the press. The hydraulic cushion cylinder is usually set in the stroke terminal position of the cylinder, and the deceleration effect is achieved through the internal buffer device.

Press Machine Hydraulic Cushion Cylinder
A hydraulic cushion cylinder for a press machine is designed to decelerate and cushion the movement of the press ram at the end of its stroke. This mechanism is essential in preventing the ram from forcefully hitting the end of the cylinder, which can lead to damage to both the machine and the workpiece.
These cylinders typically incorporate a piston with an integrated orifice that regulates the flow of hydraulic fluid. As the piston nears the completion of its stroke, the orifice restricts fluid flow, effectively slowing down the piston. The cushioning effect can be modified by altering the size of the orifice. Hydraulic cushion cylinders find applications in various press machines, including stamping, deep drawing, and forging presses. They are particularly crucial in high-speed presses, where the ram can attain speeds of several hundred feet per minute.
Factors to be Considered When Choosing Cushion Cylinders for Press Machine
Hydraulic cushion cylinders come in a diverse range of sizes and capacities tailored to various applications. When selecting a hydraulic cushion cylinder, several factors should be taken into account:
- Bore size: The bore size refers to the diameter of the piston. Choosing a hydraulic cylinder with an adequately sized bore is crucial for generating the necessary cushion force.
- Stroke length: The stroke length indicates the distance the piston can travel. It¡¯s essential to select a cylinder that meets the application¡¯s stroke length requirements.
- Cushion force: This is the maximum force the cylinder can absorb, making it vital to choose a cylinder with sufficient cushion force to protect dies and tooling from damage.
- Cushion type: The cushion type dictates how the cylinder absorbs impact, so selecting the appropriate type for the specific application is important.

Hydraulic Press Cylinder Reviews
Ethan Brooks – Plant Manager
We upgraded to these hydraulic press cylinders six months ago for our assembly line. They handle 200-ton loads without overheating, even during peak shifts. The stroke length is accurate, and we’ve had no issues with pressure drops, which used to slow us down. Maintenance is simple—mostly just checking the oil levels and fittings. The only hiccup was a slight delay in delivery, but the team kept us updated. They’re a practical choice for high-volume operations like ours.
