About the Airtac SC80 Standard Cylinder SC80X252S
The SC80X252S is an 80 mm bore double-acting pneumatic cylinder with a non-standard 252 mm stroke, built for applications requiring a specific extended length outside the standard catalog range. At 0.5 MPa it generates 2513 N of push force and 2268 N on the pull stroke, driven by a 25 mm diameter piston rod with an M20x1.5 male thread.
This model includes a built-in magnet, allowing easy mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback. The adjustable air cushion at each end decelerates the piston smoothly over a 28 mm cushion length, protecting the end caps from impact at speeds up to 800 mm/s.

Where the Airtac SC80 Standard Cylinder SC80X252S Is Used
Material Handling Pusher
The 2513 N push force at 0.5 MPa easily diverts or indexes medium-weight packages on a conveyor line. The 252 mm stroke provides the reach needed for wide belt sections, and the built-in magnet enables sensor-based cycle counting.
Clamping & Assembly Fixtures
Delivers consistent 2268 N pull force for holding parts during welding or assembly. The non-standard 252 mm stroke accommodates custom fixture depths, while the adjustable cushion prevents vibration transfer into the workpiece.
Automated Gate Actuation
Operates a sliding safety gate or diverter chute with a 252 mm travel. The magnet allows end-of-travel confirmation via DMSG sensors, ensuring the gate is fully open or closed before the next sequence step.
Is the Airtac SC80 Standard Cylinder SC80X252S the Right Cylinder?
Choose the SC80X252S when your application needs approximately 2513 N of push force and a 252 mm stroke length. If you require higher force, stepping up to the 100 mm bore provides 3927 N at the same 0.5 MPa pressure; for a smaller, lighter actuator, the 63 mm bore delivers 1559 N.
This 252 mm stroke is non-standard for the 80 mm bore, so it is a made-to-order item. For strokes of 300 mm or longer, always evaluate side-load conditions—an unsupported 25 mm rod at full extension can bend under lateral force. Use an external linear guide or a guided cylinder to absorb side loads and protect the rod bearing. When replacing an existing unit, match five points: 80 mm bore, 252 mm stroke, PT1/8 port thread, the built-in magnet (-S), and the basic mounting style.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC80 Standard Cylinder SC80X252S FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 5026 N. Always apply a safety factor for dynamic loads.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than a comparable ISO 15552 profile cylinder, so mounting dimensions are not interchangeable. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with the same bore, stroke, PT port, and magnet option.
