Target Audience: This technical guide is written for automotive distributors, engineers, repair workshops, and OEM buyers sourcing replacement gas springs or custom lift supports.
Infinite Positioning with Secure Locking
A lockable gas spring allows a user to stop and lock the stroke at any position along its travel. This is achieved via an internal valve mechanism controlled by an external release pin.
Types of Locking Mechanisms
- Elastic Locking: The spring locks in place but retains a slight "bounce" or cushioning effect. Ideal for ergonomic office chairs or vehicle seating where shock absorption is desired.
- Rigid Locking in Extension: Absolute rigidity when pulled outward. Perfect for medical examination tables.
- Rigid Locking in Compression: Absolute rigidity when pushed inward. Used in heavy-duty machinery where safety is paramount.
