About the Airtac SC80 Standard Cylinder SC80X250
The SC80X250 is a double-acting pneumatic cylinder delivering a substantial 2513 N of push force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 250 mm stroke, this model features a 25 mm diameter piston rod and a PT3/8 port for reliable air flow.
Its tie-rod construction makes it shorter than a typical ISO 15552 profile cylinder, so dimensional interchangeability should be verified. The 28 mm adjustable air cushion at each end helps decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 182 mm, giving a total extended length of approximately 432 mm for this stroke.

Where the Airtac SC80 Standard Cylinder SC80X250 Is Used
Material Transfer
Pushes heavy totes or boxes off a main conveyor line onto a gravity roller spur, using the 2513 N force at standard shop air pressure.
Waste Compaction
Drives a compaction plate in a small baler or compactor, leveraging the high 4523 N end-of-stroke force at 0.9 MPa to crush cardboard or plastic.
Clamping & Fixturing
Secures large weldments or wood panels on an assembly jig, providing consistent clamping force without the complexity of hydraulics.
Is the Airtac SC80 Standard Cylinder SC80X250 the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the 63 mm bore, which provides 1559 N at 0.5 MPa. If you need more power, the 100 mm bore offers 3927 N at the same pressure. When replacing an existing cylinder, ensure a 5-point match: 80 mm bore, 250 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and the absence of a built-in magnet. For this 250 mm stroke, ensure the load is guided and side forces are minimal, as the 25 mm rod is not designed to support significant lateral bending moments.
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 SC80X250 FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force on retraction is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
No, the SC80X250 is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston can drift or drop under load. For load holding, you must add an external pilot-operated check valve or a mechanical rod lock.
