About Air Cylinders

Select a cylinder, prolong its life by reducing wear, and trigger automated processes with sensors.

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.

Double-Acting Round Body Air Cylinders

Push and pull light duty loads. These air cylinders use compressed air to both extend and retract, so they operate at nearly full force in either direction.

Rotary Clamping Air Cylinders

Clamp items in place to complete a step in your manufacturing process.

Clean Room Round Body Air Cylinders

Minimize the release of particles that can damage electronics or contaminate batches as you push and pull light loads. These air cylinders are designed with seals and caps that prevent particles from escaping.

Dust-Resistant Round Body Air Cylinders

Push and pull light duty loads in areas constantly exposed to dust and powders as fine as flour.

Flexible-Mount ISO Air Cylinders

For multiple mounting options, these air cylinders match an industry standard ISO footprint and have threaded holes on the face and sides.

Clean Room Flexible-Mount Air Cylinders

Mount these cylinders directly to equipment in environments where contamination is a concern, such as electronics manufacturing.

Vacuum Lifting Air Cylinders

Combine the lifting power of a vacuum with the actuation of an air cylinder to automate processes such as pick and place. With a hollow rod that’s threaded to connect to a vacuum pad, these cylinders let you move items with suction.

Gas Springs

These general purpose gas springs assist in opening lids, covers, windows, conveyors, and seats—similar to a hatchback opening on a car.

Corrosion-Resistant Gas Springs

Stainless steel construction provides corrosion resistance for use in damp environments.

High-Temperature Gas Springs

A temperature-resistant seal allows these gas springs to withstand heat up to 392°F.

Add-a-Fitting Gas Springs

These gas springs have threaded ends so you can use them with any combination of end fittings, studs, and mounting brackets.

Corrosion-Resistant Add-a-Fitting Gas Springs

Made from stainless steel for excellent corrosion resistance in damp environments.

Reducible-Force Gas Springs

Ensure you have the correct force for your application. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements.

Corrosion-Resistant Reducible-Force
Gas Springs with Eyelet Fittings

Made from stainless steel for excellent corrosion resistance in damp environments. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements.

Corrosion-Resistant Locking Gas Springs

Automatically locking when fully extended and made of 316 stainless steel to resist corrosion, these gas springs protect material and equipment underneath heavy loads in damp environments.

Reducible-Force Locking Gas Springs

Ensure you have the correct force for your application. These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements.

Corrosion-Resistant Reducible-Force
Locking Gas Springs

Release gas from these springs until they supply the exact force you need—made of corrosion-resistant 316 stainless steel, they’re commonly used in wet environments.

Pulling Gas Springs

Also known as tension and traction gas springs, these work in the opposite direction of other gas springs. Similar to a screen door closing, they're used to assist in closing covers, hoods, and doors.
