About the Airtac SC80 Standard Cylinder SC80X140
The SC80X140 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, offering a 140 mm stroke within an 80 mm bore. At 0.5 MPa, it provides a push force of 2513 N, making it suitable for medium-duty clamping and pressing tasks. The 25 mm diameter piston rod and 28 mm adjustable air cushion work together to ensure smooth end-of-stroke deceleration.
This model features a body length of 182 mm and uses PT3/8 ports as standard. The tie-rod construction allows for straightforward maintenance and robust performance in industrial automation environments. Its compact design, shorter than an equivalent ISO 15552 cylinder, saves valuable machine space.

Where the Airtac SC80 Standard Cylinder SC80X140 Is Used
Part Transfer
Moves components between conveyor lines or workstations with a 140 mm linear stroke, handling moderate payloads with the 2513 N push force at 0.5 MPa.
Assembly Pressing
Applies consistent force for pressing bearings, bushings, or fasteners into assemblies, leveraging the 4523 N maximum thrust at 0.9 MPa for secure fits.
Material Clamping
Secures workpieces in CNC fixtures or welding jigs, using the double-acting action for reliable hold and release cycles in automated production.
Is the Airtac SC80 Standard Cylinder SC80X140 the Right Cylinder?
Choose the SC80X140 when your application requires a force around 2513 N at 0.5 MPa. If you need more power, stepping up to the SC100 bore provides 3927 N at the same pressure. For lower force requirements, the SC63 bore delivers 1559 N. Always ensure the 25 mm rod is adequately supported against side loads, especially as the 140 mm stroke extends.
For a direct replacement, match five key points: an 80 mm bore, 140 mm stroke, PT3/8 port thread, basic mounting (no included bracket), and no magnet. This cylinder is a tie-rod type and is dimensionally interchangeable only with another AirTAC SC80 or an equivalent tie-rod cylinder, not with ISO 15552 profile types.
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 SC80X140 FAQ
At 0.7 MPa operating pressure, the SC80X140 cylinder produces a push force of 3518 N. The pull force at the same pressure is 3175 N, accounting for the area of the 25 mm piston rod.
No, the AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. You must replace it with another AirTAC SC80 tie-rod cylinder or a compatible tie-rod model matching the 80 mm bore, 140 mm stroke, and PT3/8 ports.
