About the Airtac SC80 Standard Cylinder SC80X270S
The SC80X270S is a double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa (up to 4523 N at 0.9 MPa), making it a robust choice for medium-to-heavy linear actuation tasks. Its 80 mm bore houses a 25 mm diameter piston rod with PT3/8 ports, and the 270 mm stroke is well within the 1500 mm maximum standard stroke for this bore size.
This model includes the -S suffix for a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for precise, non-contact position sensing. The adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-travel, protecting the end caps from impact damage.

Where the Airtac SC80 Standard Cylinder SC80X270S Is Used
Material Handling Gates
Operates diverter gates on conveyor lines, using the 2513 N push force at 0.5 MPa to reliably redirect packages or bulk materials. The built-in magnet provides end-of-stroke confirmation to the PLC.
Clamping & Fixturing
Applies consistent clamping pressure for CNC machining fixtures or welding jigs. The adjustable cushion prevents vibration-induced part shift at the end of the clamping stroke.
Press-Fit Assembly
Provides the controlled linear force needed for bearing insertion or component press-fit stations. Sensor feedback from the -S magnet ensures full stroke completion before the cycle advances.
Is the Airtac SC80 Standard Cylinder SC80X270S the Right Cylinder?
Select the SC80 when your application needs more force than a 63 mm bore (1559 N at 0.5 MPa) but does not require the bulk of a 100 mm bore (3927 N at 0.5 MPa). For strokes over 300 mm, consider external guides or a guided cylinder to protect the 25 mm rod from side-load bending moments, especially with a centre-of-gravity offset load.
To ensure a correct replacement for an existing cylinder, match these five points: 80 mm bore, 270 mm stroke, PT3/8 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting configuration.
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 SC80X270S FAQ
At the standard operating pressure of 0.7 MPa, the push force is 3518 N and the pull force is 3175 N. The maximum theoretical push force at 1.0 MPa is 513 kgf (5026 N).
Yes. The -S suffix in SC80X270S denotes a built-in magnet on the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped onto the tie-rod barrel for contactless position detection without any additional brackets.
