About the Airtac SC80 Standard Cylinder SC80X8
The AirTAC SC80X8 is a compact-stroke double-acting pneumatic cylinder from the SC tie-rod series, built with an 80 mm bore and a short 8 mm stroke. At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force, making it suitable for precise short-travel clamping, ejecting, or positioning tasks where space is tight.
This model uses a 25 mm diameter piston rod with M20×1.5 male threads and PT3/8 ports. The body length A is 182 mm, giving a total extended length of approximately 190 mm. An adjustable air cushion (28 mm long) decelerates the piston near stroke end to reduce impact, while the standard TPU seals and PT threads suit general industrial environments from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X8 Is Used
Short-Stroke Clamping
The 8 mm stroke and 2513 N push force at 0.5 MPa make the SC80X8 ideal for pneumatic clamping fixtures where the jaw travel is minimal but holding force must be high.
Precision Ejection
In automated assembly cells, this cylinder ejects small components from nests or tooling with a controlled, repeatable 8 mm linear movement and adjustable end-of-stroke cushioning.
Part Stops & Gates
Use the SC80X8 as a pneumatic stop or diverter gate on a conveyor line. Its short stroke and robust 25 mm rod provide fast actuation for lightweight product routing.
Is the Airtac SC80 Standard Cylinder SC80X8 the Right Cylinder?
Choose the SC80X8 when you need a high-force 80 mm bore in a very short stroke. If the 2513 N push at 0.5 MPa is too low, stepping up to the SC100 bore delivers 3927 N; if it is more force than required, the SC63 bore provides 1559 N at the same pressure. For any stroke of 300 mm or more, add an external guide or switch to a guided cylinder to protect the rod bearing from side loads.
When replacing an existing cylinder, match five points exactly: 80 mm bore, 8 mm stroke, PT3/8 port thread, the basic (no bracket) mounting configuration, and the absence of a magnet. This ensures the SC80X8 drops into the same footprint and pneumatic circuit without modification.
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 SC80X8 FAQ
At 0.5 MPa the SC80X8 delivers 2513 N push and 2268 N pull. At 0.7 MPa it reaches 3518 N push, and at the maximum operating pressure of 0.9 MPa it produces 4523 N push force. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. Only replace another AirTAC SC80 tie-rod cylinder with matching bore, stroke, port thread (PT), mounting, and magnet option.
