About the Airtac SC80 Standard Cylinder SC80X270STC
The SC80X270STC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa). Its 270 mm stroke suits medium-reach clamping, pressing, and material-transfer tasks where a compact tie-rod design is preferred over a longer ISO 15552 profile.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus a centre trunnion (TC) mount with TCM1 bracket (F-SC80TC) for pivoting applications. The 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration, while the PT1/4 port thread keeps plumbing straightforward.

Where the Airtac SC80 Standard Cylinder SC80X270STC Is Used
Pivoting Conveyor Gates
The centre trunnion mount lets the cylinder swing as it extends, making it ideal for diverting packages or product on conveyor lines.
Clamping & Fixturing
With 2513 N at 0.5 MPa and magnetic piston sensing, this cylinder confirms clamp position in automated welding or assembly fixtures.
Material Handling Pushers
The 270 mm stroke pushes bins or cartons off a line. The adjustable cushion absorbs impact at end of stroke, protecting the load and cylinder.
Is the Airtac SC80 Standard Cylinder SC80X270STC the Right Cylinder?
Choose the SC80 when your application needs roughly 2513 N at 0.5 MPa. If you can accept less force, stepping down to the SC63 (1559 N at 0.5 MPa) saves space; for heavier loads, the SC100 provides 3927 N at the same pressure. For this 270 mm stroke, ensure side loads are minimal or use an external guide—long unsupported rods can bend under off-axis forces.
For a direct replacement, match bore (80 mm), stroke (270 mm), port thread (PT), centre trunnion mount (TC with TCM1 bracket), and the built-in magnet (-S). The SC is a tie-rod cylinder, not an ISO 15552 interchangeable unit, so dimensional checks against the original AirTAC SC are essential.
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 SC80X270STC FAQ
At 0.5 MPa it produces 2513 N extending and 2268 N retracting. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. Always size for your working pressure.
No. The SC80 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centred. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
