Hahn's gas springs with locking function can be locked at any position within the stroke range. By pressing the release pin at the tip of the piston rod using a lever or hydraulic release, the valve inside the cylinder opens, releasing the lock and allowing the piston rod to be compressed or extended. We offer five different types with varying locking functions and a wide range of release options, so you can choose the appropriate spring according to your application. We accept orders from just one piece, so they can be used not only for mass production but also for prototypes and research purposes.

We offer a rich lineup of products. You can order from just one piece, making it ideal for research and development, prototyping, and small-scale production. 【Features of HAHN Gas Springs】 - We have a wide range of products, including standard gas springs, gas springs with locking functions, retractable tension springs, and oil dampers. - Custom orders can be made from just one piece. - Detailed specifications such as stroke length, overall length, and gas reaction force can be discussed. - Mini-sized gas springs, such as the G02-06 with a rod diameter of 2mm and a cylinder diameter of 6mm, are also available. - You can choose mounting brackets from a wide selection. - Two types of stainless steel are available (equivalent to SUS304 and SUS316). - High-safety oils suitable for food machinery can also be selected. 《Products from HAHN》 - Gas Springs - Tension Springs - Gas Springs with Locking Mechanism - Oil Dampers - Sliding Door Dampers - Double Stroke Gas Springs For more details, please contact us.

A "gas spring" contains compressed non-flammable nitrogen gas sealed inside the cylinder, and this gas pressure acts as a spring to push out the piston rod. As the piston rod contracts, the volume inside the cylinder decreases, compressing the gas. This increases the gas reaction force. Additionally, oil for lubricating the piston rod is included inside the cylinder, which creates hydraulic resistance just before the piston rod fully extends. 【Features】 ■ The piston rod is always in the maximum extended position when there is no load. ■ As the piston rod contracts, the volume inside the cylinder decreases, compressing the gas and increasing the gas reaction force. ■ The gas reaction force is proportional to the diameter of the piston rod and the diameter of the cylinder. ■ Oil for lubricating the piston rod is included inside the cylinder. ■ Hydraulic resistance occurs just before the piston rod fully extends. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the features of the "Gas Spring" that we handle. It is compact and lightweight, with smooth operation. The spring constant and gas reaction can be set over a wide range. Additionally, it can be designed according to the application, making it suitable for a wide variety of uses. 【Features】 ■ Due to the small spring constant, it provides almost constant spring force over a wide range of strokes. ■ The spring constant and gas reaction can be set over a wide range. ■ Compact and lightweight. ■ Smooth operation. ■ Can be designed according to the application, allowing for a wide range of uses. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce a case study of the introduction of gas springs to a machinery manufacturer. In a machine used for metal processing, fine iron powder generated internally was adhering to the piston rod. Foreign substances were entering the cylinder, causing damage to the seals and leading to gas leaks. In response, we proposed an option called the "wiper ring" to prevent the iron powder adhering to the piston rod from entering the cylinder, as well as an optional "protective tube" to minimize the adhesion of iron powder to the piston rod. After implementation, the longevity of the gas springs was achieved, and the production line has not stopped for several years, contributing to improved productivity. [Results of Implementation] - Achieved longevity of gas springs - The production line has not stopped for several years, contributing to improved productivity *For more details, please refer to the PDF document or feel free to contact us.

This catalog offers a wide range of "gas springs." It provides detailed information on the composition and function of gas springs, as well as how to place an order.

We would like to introduce our "gas springs." Inside the cylinder, compressed nitrogen gas and oil are sealed, and the pressure within the cylinder is applied to the cross-section of the piston rod, resulting in an extension force. Gas springs contain oil within the cylinder to lubricate the piston rod, and this oil also has the function of providing hydraulic resistance just before the piston rod fully extends. 【Product Lineup】 ■ Gas Springs ■ Gas Springs with Locking Function ■ Tension Springs *For more details, please refer to the PDF document or feel free to contact us.

Hahn products are not safety components. Gas springs, tension springs, and oil dampers are maintenance-free, but since they are consumables, it is necessary to regularly test their functionality according to the usage environment and application. To use the products for a longer time, they need to be protected especially from corrosion. 【Tolerances/Characteristics (Partial)】 ■ Maximum stroke speed of gas springs = 300mm/s (when installed) ■ Tolerance of the overall length of the product = ±2mm ■ The damping force of adjustable oil dampers can be increased or decreased by rotating the piston rod at the maximum extension and maximum compression positions ■ The overall length changes when the piston rod is rotated ■ When the ambient temperature changes, the characteristics of the oil filled in the product change *For more details, please refer to the PDF document or feel free to contact us.
