About the Airtac SC80 Standard Cylinder SC80X90
The SC80X90 is an 80 mm bore double-acting tie-rod cylinder with a 90 mm stroke, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide smooth deceleration for mid-range automation tasks.
With a compact body length A of 182 mm and PT3/8 ports, this cylinder suits installations where space is tighter than an ISO 15552 profile but robust force is still required. It operates on filtered air from -20 to +70 °C with standard TPU seals, making it a reliable workhorse for general industrial applications.

Where the Airtac SC80 Standard Cylinder SC80X90 Is Used
Package Sorting Gate
The 90 mm stroke provides a quick, decisive push to divert cartons on a conveyor line. The 2513 N force at standard shop air easily handles a sorting gate mechanism.
Clamping in CNC Fixtures
Applies 4523 N of clamping force at 0.9 MPa to secure workpieces for milling or drilling. The adjustable cushion prevents vibration marks on the part at the end of the stroke.
Press-Fit Assembly
Delivers a controlled 90 mm press stroke for inserting bearings or bushings into housings. The rigid tie-rod construction handles the repetitive axial loads without flexing.
Is the Airtac SC80 Standard Cylinder SC80X90 the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of push force. If the load is lighter, stepping down to the SC63 bore (1559 N at 0.5 MPa) can reduce air consumption and physical size. For heavier demands, the SC100 bore provides 3927 N at the same 0.5 MPa pressure.
For a direct replacement, match five key points: 80 mm bore, 90 mm stroke, PT3/8 port thread, basic (no mounting accessory), and no magnet. This ensures the new cylinder drops into the existing tie-rod footprint without re-engineering the machine.
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 SC80X90 FAQ
At 0.7 MPa operating pressure, the theoretical push force is 3518 N and the pull force on the retract stroke is 3175 N. These values are based on the 80 mm bore and 25 mm rod diameter.
No, the SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. It will not be dimensionally interchangeable. It is a direct replacement only for another AirTAC SC80 or equivalent tie-rod cylinder with the same bore, stroke, and port thread.
