About the Airtac SC80 Standard Cylinder SC80X20STC
The SC80X20STC is a short-stroke double-acting tie-rod cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa). Its 80 mm bore and 20 mm stroke suit compact clamping, ejecting, or positioning tasks where space is tight but high force is needed.
This model includes a built-in magnet (-S) for barrel-mounted CMSG/DMSG/EMSG sensors, plus a centre trunnion mount (TC) with TCM1 bracket (F-SC80TC) for pivoting applications. The 25 mm rod, PT3/8 ports, and 28 mm adjustable air cushion ensure smooth, controlled end-of-stroke deceleration.

Where the Airtac SC80 Standard Cylinder SC80X20STC Is Used
Short-Stroke Clamping
High force in a compact 20 mm stroke for fixturing, pressing, or holding workpieces during machining or assembly.
Sensor-Controlled Ejection
Built-in magnet enables end-of-stroke sensing to confirm part ejection or retraction in automated cells.
Pivoting Gate Actuation
Centre trunnion mount allows the cylinder to swing, ideal for diverting parts on conveyors or chutes.
Is the Airtac SC80 Standard Cylinder SC80X20STC the Right Cylinder?
Choose the SC80X20STC when you need 2.5 kN class force in a very short stroke. If 2.5 kN is marginal, stepping up to the 100 mm bore provides 3927 N at 0.5 MPa. For longer strokes up to 1500 mm in the same bore, the SC80 series offers standard options.
For a direct replacement, match five points: 80 mm bore, 20 mm stroke, PT3/8 ports, centre trunnion (TC) mount, and the built-in magnet (-S). The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC80 tie-rod units.
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 SC80X20STC FAQ
At 0.5 MPa air pressure, the push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix denotes a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel for piston position detection.
