About the Airtac SC80 Standard Cylinder SC80X1150S
The SC80X1150S is a double-acting pneumatic cylinder with an 80 mm bore and a 1150 mm stroke, equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors. At 0.5 MPa it provides 2513 N of push force, rising to 4523 N at the maximum operating pressure of 0.9 MPa, making it a strong workhorse for long linear movements.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 ports. The total extended body length is approximately 1364 mm, based on a 182 mm body length plus the stroke. The adjustable pneumatic cushion at each end (28 mm length) decelerates the piston smoothly, protecting the end caps during high-speed operation.

Where the Airtac SC80 Standard Cylinder SC80X1150S Is Used
Long-Stroke Material Transfer
Pushes or pulls heavy bins and pallets across wide conveyor junctions, using the full 1150 mm stroke and 2513 N of force at standard line pressure.
Automated Welding Fixtures
Positions large weldments or clamps in automated cells. The built-in magnet enables sensor feedback to confirm clamp engagement before the cycle starts.
Sawmill Log Flippers
Provides the high force and long travel needed to rotate or kick heavy timber on a sorting line, with the adjustable cushion softening the impact at stroke ends.
Is the Airtac SC80 Standard Cylinder SC80X1150S the Right Cylinder?
For applications needing slightly less force, the 63 mm bore SC63 series offers 1559 N at 0.5 MPa, while stepping up to the 100 mm bore provides 3927 N. When ordering a direct replacement, ensure all five points match: 80 mm bore, 1150 mm stroke, PT3/8 port thread, the built-in magnet (-S suffix), and the basic mounting configuration.
With a stroke length of 1150 mm, this cylinder has a long, unsupported rod extension. To prevent rod bending or bearing damage from side loads, always guide the load externally with a linear rail or rodless actuator. The built-in magnet allows you to clamp CMSG/DMSG sensors directly onto the tie-rod barrel for reliable end-of-stroke or mid-stroke position feedback without additional brackets.
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 SC80X1150S FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston, which is required for mounting CMSG, DMSG, or EMSG solid-state sensors directly onto the cylinder's tie-rod barrel. Without the magnet, these sensors cannot detect piston position.
