About the Airtac SC80 Standard Cylinder SC80X55
The SC80X55 is an 80 mm bore, 55 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. Operating at 0.5 MPa, it provides a push force of 2513 N and a pull force of 2268 N, making it a solid mid-range actuator for clamping and pressing tasks. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end help manage end-of-stroke deceleration in a compact 182 mm body length.
This 80 mm bore model uses PT3/8 pneumatic ports and an M20x1.5 rod thread for straightforward connection to standard fittings and tooling. With a maximum standard stroke of 1500 mm, this 55 mm stroke unit is a stock configuration, ready for immediate dispatch from genuine AirTAC inventory.

Where the Airtac SC80 Standard Cylinder SC80X55 Is Used
Package Diverting
The 55 mm stroke and 2513 N push force at 0.5 MPa are ideal for a fast-acting diverter gate on a packaging conveyor, reliably pushing cartons onto a parallel lane.
Assembly Press
Delivers a controlled 4523 N of force at 0.9 MPa for pressing bearings or bushings into housings. The 28 mm adjustable cushion softens the impact at full extension.
Clamping Fixture
Use this double-acting cylinder for a pneumatic clamping station. The 25 mm rod resists bending under direct axial loads, securing parts for welding or machining.
Is the Airtac SC80 Standard Cylinder SC80X55 the Right Cylinder?
Choose the SC80X55 when your application needs around 2500 N of force at standard line pressure. If you require less force, stepping down to the 63 mm bore (1559 N push at 0.5 MPa) can reduce air consumption and physical size. For higher force demands, the 100 mm bore delivers 3927 N push at the same pressure. When replacing an existing cylinder, match all five key points: 80 mm bore, 55 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and the absence of a magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X55 FAQ
At 0.7 MPa operating pressure, the SC80X55 produces a theoretical push force of 3518 N. The maximum push force at the 0.9 MPa operating limit is 4523 N. Always size your cylinder based on the force required at your specific available pressure.
This specific model code does not include the '-S' magnet option, so the piston does not have a magnetic ring. To use CMSG or DMSG sensors for position feedback, order the SC80X55-S variant which has a built-in magnet. Sensors clamp directly onto the tie-rod barrel.
