About Air Cylinders

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

Miniature Threaded-Body Air Cylinders

These cylinders thread directly into your equipment, taking minimal space.

Impact-Resistant Round Body Air Cylinders

Built to withstand hard knocks, these cylinders have a thick barrel wall for more durability than standard air cylinders. They combine the form of a round body air cylinder with the rugged construction of a tie-rod body air cylinder. All are double acting; they use air to exert force in both directions.

Universal Mount

Universal-mount cylinders have threads on both ends to mount in a fixed position, or you can use the hole on the back end to pivot mount. They come with two nuts and a pivot pin with retaining rings.

Sensor-Ready Nose Mount

Image of Product. Front orientation. Contains Annotated. Air Cylinders. Impact-Resistant Round Body Air Cylinders, Nose Mount.

Sensor-ready cylinders have a magnetic piston to activate relays and controllers. When the piston moves past the sensor (sold separately), the sensor activates. You can use multiple sensors. Attach one for each action you want to trigger.

Nose-mount cylinders have threads and a nut on the front of the cylinder and install in a fixed position horizontally or vertically.

Rod Alignment Couplers

Angle of Misalignment

Increase cylinder life by fixing alignment problems between air or hydraulic cylinders and driven components. Couplers have a threaded end that moves to compensate for the angle of misalignment, reducing wear on cylinder bearings and seals. Couplers have a male and female end.
