About the Airtac SC80 Standard Cylinder SC80X355
The SC80X355 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 355 mm stroke. At 0.5 MPa it produces 2513 N of push force, rising to a robust 4523 N at the 0.9 MPa maximum operating pressure, driven by a 25 mm diameter piston rod.
This cylinder features a body length A of 182 mm, giving a total extended length of approximately 537 mm. The adjustable air cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact. It uses PT3/8 ports and operates on filtered air from -20 to +70 °C with standard TPU seals.

Where the Airtac SC80 Standard Cylinder SC80X355 Is Used
Material Reject Gates
The 355 mm stroke and 2513 N push force at 0.5 MPa are well-suited for actuating diverter gates on wide conveyor lines, reliably pushing products off the belt for sorting.
Clamping Large Assemblies
With 4523 N of force at 0.9 MPa, this cylinder provides the high clamping pressure needed to secure large weldments or glued assemblies in a fixture during curing.
Pallet Layer Forming
The long 355 mm stroke enables a pusher plate to sweep a full layer of cases onto a pallet, with the adjustable cushion ensuring a gentle stop at the end of travel to protect the load.
Is the Airtac SC80 Standard Cylinder SC80X355 the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N at 0.5 MPa. If space is tight and less force is acceptable, the 63 mm bore SC63 delivers 1559 N at the same pressure. Always match the bore, 355 mm stroke, PT3/8 port thread, and basic mounting when replacing an existing SC80 cylinder.
At a 355 mm stroke, the 25 mm rod is cantilevered significantly when extended. Any side load, even minor misalignment, creates a bending moment on the rod bearing. For long-stroke applications, use an external linear guide or a guided cylinder to absorb side forces and prevent premature rod bearing wear or rod buckling.
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 SC80X355 FAQ
At 0.5 MPa (5 bar), 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.
No. The SC80X355 is not designed for direct side loads. The 25 mm rod extended to 355 mm is vulnerable to bending. You must use an external guide rail, rod alignment coupler, or switch to a guided cylinder to prevent damage to the rod bearing and seals.
