About the Airtac SC80 Standard Cylinder SC80X253SN
The SC80X253SN is an 80 mm bore, 253 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, driven by a 25 mm diameter piston rod. The 28 mm adjustable air cushion at each end decelerates the piston smoothly, reducing end-of-stroke impact.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the barrel for non-contact position sensing. The NBR seal (-N suffix) provides reliable sealing for standard industrial air, and the PT1/4 port threads connect to common pneumatic fittings. With a body length of 182 mm, the total extended length is approximately 435 mm.

Where the Airtac SC80 Standard Cylinder SC80X253SN Is Used
Material Handling Pushers
The 2513 N push force at 0.5 MPa easily moves boxes or pallets on a conveyor line, and the built-in magnet enables precise end-of-stroke detection for automated sorting.
Clamping & Fixturing
Delivers a strong, consistent clamping force for CNC machining or welding jigs. The NBR seals are well-suited for oily shop air environments.
Lifting & Tilt Mechanisms
With 2268 N of pull force, this cylinder can control a tilt chute or a simple lift-assist arm. The adjustable cushion protects the mechanism from hard stops.
Is the Airtac SC80 Standard Cylinder SC80X253SN the Right Cylinder?
For applications needing slightly less force, the 63 mm bore SC63 series offers 1559 N push at 0.5 MPa. If more force is required, stepping up to the 100 mm bore SC100 series provides 3927 N at the same pressure. Always match bore, stroke, port thread (PT), mounting, and magnet option when replacing an existing cylinder.
At a 253 mm stroke, the 25 mm rod is robust for most axial loads. However, if the application involves any significant side loading, consider adding an external guide rail or switching to a guided cylinder to prevent rod bending and premature bearing wear.
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 SC80X253SN FAQ
At the standard operating pressure of 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 reaches 4523 N.
Yes. The '-S' in the model code indicates a built-in magnet on the piston. This allows you to clamp compatible CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's tie-rod slots for reliable position feedback.
