About the Airtac SC80 Standard Cylinder SC80X80
The SC80X80 is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and 80 mm stroke, this model features a 25 mm diameter piston rod and PT3/8 ports, making it a robust choice for medium-force clamping and pressing tasks.
This tie-rod cylinder includes an adjustable air cushion (28 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 182 mm, giving a total extended length of 262 mm. It operates on filtered air from 0.15 to 1.0 MPa and comes standard with TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X80 Is Used
Part Transfer
Pushes or lifts components between conveyor lines or indexing tables with 2513 N of force at 0.5 MPa, ideal for short, rapid transfer strokes.
Assembly Press
Provides a controlled 80 mm pressing stroke for bearing insertion or riveting, using the adjustable cushion to soften the impact at full extension.
Clamping Fixture
Secures workpieces in CNC or welding fixtures. The 25 mm rod and tie-rod construction offer rigidity for consistent clamping force.
Is the Airtac SC80 Standard Cylinder SC80X80 the Right Cylinder?
Select the SC80X80 when your application needs roughly 2500 N of force at standard plant pressure. If you require less force, stepping down to the 63 mm bore (1559 N at 0.5 MPa) can reduce air consumption and physical size. For higher force, the 100 mm bore provides 3927 N at the same pressure. Always match the replacement cylinder on five points: bore, stroke, port thread (PT), mounting accessory, and magnet option.
For this 80 mm stroke, side loading is typically not a primary concern, but ensure the rod is aligned with the load to prevent premature bearing wear. If the load path is not perfectly linear, consider an external guide or a guided cylinder variant.
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 SC80X80 FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder. It is not a drop-in replacement for ISO 15552 types. It is a direct match for another AirTAC SC tie-rod cylinder with the same bore, stroke, port thread, and mounting.
