About the Airtac SC80 Standard Cylinder SC80X255S
The SC80X255S is a double-acting pneumatic cylinder with an 80 mm bore and a 255 mm stroke, delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa. The built-in magnet (suffix -S) allows CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing, making it ready for automated sequence control without extra brackets.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 ports. The adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-stroke, reducing impact noise. With a body length A of 182 mm, the total extended length is approximately 437 mm. The standard TPU seals provide a working temperature range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X255S Is Used
Sensor-Monitored Part Transfer
The built-in magnet enables CMSG/DMSG sensors to confirm end-of-stroke, ideal for pick-and-place or diverting stations on packaging lines where cycle verification is required.
Automated Clamping & Fixturing
With 2513 N of clamping force at 0.5 MPa, this cylinder secures workpieces in CNC machining centres. Magnetic sensors signal the controller when the clamp is fully open or closed.
Press & Assembly Tool Actuation
Delivers up to 4523 N of push force for pressing bearings, rivets, or assembly components. The adjustable cushion protects tooling from impact damage at high cycle rates.
Is the Airtac SC80 Standard Cylinder SC80X255S the Right Cylinder?
The SC80 provides 2513 N at 0.5 MPa. If your load requires more force, stepping up to the SC100 bore delivers 3927 N at the same pressure; for a lighter, more compact solution, the SC63 bore offers 1559 N. Always match the replacement cylinder on all five critical points: bore, stroke, PT3/8 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
At a 255 mm stroke, the 25 mm rod is well-supported for axial loads. For applications with any side force, use an external guide rail or a guided cylinder to protect the rod bearing from bending and premature seal wear.
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 SC80X255S FAQ
At the standard operating pressure of 0.7 MPa, the push force is 3518 N and the pull force is 2268 N. The maximum push force at 0.9 MPa is 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
This is a direct replacement for another AirTAC SC80 cylinder with a 255 mm stroke, PT3/8 ports, a built-in magnet, and basic mounting. It is a tie-rod design, not an ISO 15552 profile cylinder, so it will not drop into ISO 15552 footprints. Verify your existing port thread, mounting, and sensor requirement match.
