About the Airtac SE80 Standard Cylinder SE80X300
The AirTAC SE80X300 is a double-acting single-rod profile cylinder built to the ISO 15552 standard. It delivers a robust 2513 N push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machinery frames.
This 80mm bore unit features a 300mm stroke and a PT3/8 port. Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling. This specific SKU is supplied without a built-in magnet, meaning it does not support direct CMSE or DMSE position sensing without modification.

Where the Airtac SE80 Standard Cylinder SE80X300 Is Used
Palletizer Case Erector
Provides 2513 N of push force at 0.5 MPa to fold and seal heavy corrugated cardboard cases on automated packaging lines.
Press Brake Backgauge
Utilizes the 300mm stroke to position sheet metal accurately during bending, relying on the extruded profile for rigid, flush mounting.
Injection Mold Platen Ejector
Leverages the adjustable air cushion to decelerate the 25mm rod smoothly when ejecting dense molded parts at high cycling speeds.
Is the Airtac SE80 Standard Cylinder SE80X300 the Right Cylinder?
Stepping down to the 63mm bore reduces the 0.5 MPa push force to 1559 N, whereas moving up to the 100mm bore increases it to 3927 N. Because this is a plain double-acting cylinder, it cannot hold a load if air pressure drops—the piston will drift—so a BSE rod lock variant is necessary for fail-safe holding. At 300mm of stroke, the 25mm rod and front bearing face higher bending moments under side loads, so an external guide rail is recommended to prevent premature wear. As a true ISO 15552 cylinder, it serves as a drop-in replacement sharing standard mounting dimensions and PT3/8 ports.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE 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 (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE80 Standard Cylinder SE80X300 FAQ
The SE80X300 delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a maximum push force of 513 kgf at 1.0 MPa. It features an 80mm bore, a 300mm stroke, and a maximum standard stroke limit of 1500mm for this bore size.
No, the standard SE80X300 is double-acting and cannot hold a load if air is lost or the valve is centered; the piston will drift. Additionally, its adjustable air cushion only decelerates the piston near the stroke end and does not act as a brake. For secure position holding, use a BSE rod lock cylinder or an external pilot-operated check valve.
