About the Airtac SC80 Standard Cylinder SC80X550S
The SC80X550S 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, 25 mm piston rod, and a 550 mm stroke, this model is built for medium-to-heavy linear actuation tasks where long travel and consistent force are required.
This variant includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for reliable end-of-stroke or mid-position detection. The adjustable air cushion at each end decelerates the 28 mm cushion stroke to protect the end caps, while the PT3/8 port thread ensures straightforward pneumatic connection.

Where the Airtac SC80 Standard Cylinder SC80X550S Is Used
Long-Stroke Material Transfer
The 550 mm stroke and 2513 N force at 0.5 MPa are ideal for pushing heavy bins or pallets across wide roller conveyors in packaging and logistics lines.
Automated Clamping & Riveting
Delivers the high 4523 N force at 0.9 MPa for pneumatic press-fit or riveting stations, with the built-in magnet enabling precise sensor feedback for cycle control.
Agricultural Gate or Chute Actuation
Operates remote gates or diverter chutes on silos and grain handling equipment, with the sensor confirming open/closed status to the central PLC.
Is the Airtac SC80 Standard Cylinder SC80X550S the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 63 mm bore SC63 series offers 1559 N at the same pressure. At a 550 mm stroke, ensure the 25 mm piston rod is adequately supported against side loads; an external linear guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
To guarantee a direct replacement, match these five points: 80 mm bore, 550 mm stroke, PT3/8 port thread, the built-in magnet for sensor mounting, and the basic (no bracket) mounting configuration. This 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 SC80X550S FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 4523 N.
No. The SC80X550S is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. For load-holding safety, an external rod brake, mechanical lock, or pilot-operated check valve must be integrated into the circuit.
