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. A rod seal wipes grease particles off the rod as it moves back and forth. The seal is polyurethane, which is slippery, so it wears more slowly than standard seals, releasing fewer particles. These cylinders also have tightly crimped end caps to stop air from leaking.
With no tie rods on the outside, these round-body cylinders fit in tight spaces. They have an ISO industry-standard footprint that fits common mounting patterns for easy interchangeability. As universal-mount cylinders, they have mounting threads on both ends, giving you more mounting options than nose-mount cylinders. You can also pivot mount them with the through-hole on the back. They’re double acting, meaning they push and pull loads with equal force.
The piston is magnetic, so you can use these cylinders with sensors (sold separately) to activate relays and controllers. When the piston moves past a sensor, the sensor activates. You can use multiple sensors—one for each action you want to trigger.
