About the Airtac SC80 Standard Cylinder SC80X135S
The SC80X135S is a double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a strong mid-range actuator for industrial automation. With an 80 mm bore, 135 mm stroke, and 25 mm diameter piston rod, it provides a balanced combination of force and compactness, fitting into spaces where a standard ISO 15552 cylinder would be too long.
This model includes the -S suffix, indicating a built-in magnet along the barrel. This allows easy mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod tube for reliable, non-contact position sensing. The body length A is 182 mm, giving a total extended length of approximately 317 mm, and it uses PT1/4 ports with an adjustable air cushion of 28 mm.

Where the Airtac SC80 Standard Cylinder SC80X135S Is Used
Material Handling Gates
The 2513 N push force at standard line pressure is ideal for operating diverter gates and stops on conveyor systems, with the built-in magnet providing end-of-stroke confirmation.
Clamping & Holding Fixtures
Delivers consistent clamping force for CNC machining fixtures or welding jigs. The adjustable cushion reduces impact noise and vibration at the end of the 135 mm stroke.
Press & Assembly Operations
Suitable for light to medium pressing, riveting, or component insertion tasks, where the 4523 N maximum force at 0.9 MPa provides a robust power reserve.
Is the Airtac SC80 Standard Cylinder SC80X135S the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of force; if you require less, the SC63 bore offers 1559 N at 0.5 MPa in a lighter package. For strokes over 300 mm with this 25 mm rod, be mindful of side loads—consider an external guide or a guided cylinder to prevent rod bearing damage and ensure long seal life.
For a direct replacement, match these five points: 80 mm bore, 135 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC80X135S FAQ
At 0.5 MPa, it generates 2513 N pushing and 2268 N pulling. The maximum operating force at 0.9 MPa is 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix means it has a factory-installed magnet. You can clamp AirTAC CMSG, DMSG, or EMSG sensors directly to the cylinder body to detect piston position without any additional brackets.
