About the Airtac SC80 Standard Cylinder SC80X256S
The AirTAC SC80X256S is a double-acting pneumatic cylinder with an 80 mm bore and a 256 mm stroke, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide smooth deceleration for mid-stroke positioning tasks.
This model includes the -S suffix, indicating a built-in magnet embedded in the piston. This allows easy mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for contactless position feedback, making it a practical choice for automated sequences requiring end-of-stroke or intermediate position confirmation.

Where the Airtac SC80 Standard Cylinder SC80X256S Is Used
Automated Assembly & Pick-and-Place
The 256 mm stroke and sensor-ready design suit pick-and-place units where mid-stroke sensing confirms gripper position before part transfer, ensuring reliable cycle completion.
Product Sorting & Diverting Gates
Use the SC80X256S to actuate diverter gates on conveyor lines. The built-in magnet allows sensors to verify gate open/closed status, preventing jams and ensuring accurate product routing.
Palletising & Material Handling
Provides the 2513 N force needed to push boxes or totes onto pallets. The adjustable cushion protects the cylinder and load from impact damage during high-speed palletising operations.
Is the Airtac SC80 Standard Cylinder SC80X256S the Right Cylinder?
Select the SC80 bore when your application needs between 2513 N and 4523 N of push force. If your load requires less force, stepping down to the SC63 bore provides 1559 N at 0.5 MPa in a lighter, more compact body. For higher force demands, the SC100 bore offers 3927 N at the same pressure.
With a 256 mm stroke, ensure the rod is not subjected to significant side loading, as this can cause bending or premature bearing wear. For applications with misalignment or lateral forces, use an external guide rail or a guided cylinder. When replacing an existing unit, match the 80 mm bore, 256 mm stroke, PT port thread, basic mounting, and the -S magnet option to maintain sensor compatibility.
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 SC80X256S 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 increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The -S suffix in the model code SC80X256S means it has a built-in magnet. You can directly clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel to detect piston position without additional brackets.
