About the Airtac SC80 Standard Cylinder SC80X300
The AirTAC SC80X300 is a double-acting single-rod pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa). Its 80 mm bore and 300 mm stroke suit medium-duty linear tasks where a compact tie-rod body is preferred.
This model features a 25 mm diameter piston rod, PT3/8 ports, and a 28 mm adjustable air cushion at each end. The body length A is 182 mm, giving an approximate extended length of 482 mm. Operating pressure spans 0.15-1.0 MPa with TPU seals rated for -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X300 Is Used
Package Sorting Gate
Actuates a diverter arm on a conveyor line. The 300 mm stroke gives enough travel to redirect cartons between lanes, and the adjustable cushion softens the end-of-stroke impact for quiet, reliable sorting.
Clamping & Fixturing
Provides 2.5 kN of clamping force for woodworking or metal fabrication jigs. The tie-rod construction handles repetitive cycling, and the 25 mm rod resists bending under direct axial loads.
Pallet Stop & Lift
Raises a stop blade or lift table segment in a pallet-handling station. The 80 mm bore offers ample force to lift a loaded pallet corner, while the 300 mm stroke accommodates standard pallet heights.
Is the Airtac SC80 Standard Cylinder SC80X300 the Right Cylinder?
Choose the SC80X300 when your application needs roughly 2500 N at standard shop air. If you require more force, the SC100 bore steps up to 3927 N push at 0.5 MPa; for a lighter, more compact actuator, the SC63 delivers 1559 N. At 300 mm stroke, ensure side loads are minimal—long unsupported rods can bend under off-axis forces. Add an external guide or switch to a guided cylinder if the load is not perfectly aligned.
For direct replacement, match five points: 80 mm bore, 300 mm stroke, PT3/8 port thread, basic mounting (no brackets), and no magnet. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X300 FAQ
At 0.7 MPa (7 bar) the SC80X300 generates 3518 N of push force. The pull force on the retract stroke is 2268 N at 0.5 MPa due to the rod area. Maximum operating force at 0.9 MPa is 4523 N push.
No. The SC80X300 is a standard double-acting cylinder and will drift or drop if supply pressure is exhausted or the directional valve is centered. For load holding without live pressure, add a pilot-operated check valve or an external rod lock.
