Compact air cylinders feature small diameter bores and short strokes for use in lifting and positioning applications where space is a concern. Double-acting compact air cylinders interact with pressurized air to both extend and retract the actuator rod, allowing for motion control in both directions. Single-acting compact air cylinders have one inlet for pressurized air to provide motion control in one direction. Mounting hardware provides multiple options for installing compact air cylinders. Replacement parts and accessories repair worn or damaged components in compatible compact air cylinders.
