About Gas Springs
Gas springs are typically used to assist in opening lids, covers, windows, conveyors, and seats—similar to a hatchback opening on a car.

Compact Tie Rod Air Cylinders
Get the power and stroke of other tie rod cylinders in less than half the space. Cylinders have holes for mounting; one end must be mounted against a solid surface.
Sensor-ready cylinders have a magnetic piston that can trigger one or more sensors (sold separately) to activate relays and controllers.

Nonrotating Compact Tie Rod Air Cylinders
These cylinders have two parallel piston rods that prevent the head from twisting as they extend and retract. They pack force into a smaller footprint than our other tie rod cylinders. Cylinders have holes for mounting; the back end must be mounted against a solid surface.
Impact-Resistant Compact Tie Rod Air Cylinders
Small and durable, these cylinders have a high-strength plastic composite barrel that doesn’t dent. Cylinders have holes for mounting; the back end must be mounted against a solid surface.
