About the Airtac SE63 Standard Cylinder SE63AX35
The AirTAC SE63AX35 is a double-acting single-rod ISO 15552 profile cylinder with a 63 mm bore and 35 mm stroke. It generates 1559 N of push force at 0.5 MPa and 2182 N at 0.7 MPa. This unit features a SUS420J2 stainless steel piston rod, making it highly suitable for corrosive environments or washdown duty where a standard carbon steel rod would degrade.
Unlike traditional tie-rod designs, the SE series uses a square extruded aluminum barrel without external tie rods, resulting in a compact, corrosion-resistant body that mounts flush against machine frames. The barrel also integrates sensor grooves on three sides, though this specific SKU lacks the built-in magnet, meaning it cannot host CMSE or DMSE electronic position sensors without modification.

Where the Airtac SE63 Standard Cylinder SE63AX35 Is Used
Chemical Processing Valve
Actuates diverter valves in chemical plants, utilizing the SUS420J2 stainless rod to resist corrosive vapors while providing 1559 N of actuation force.
Food Washdown Flap
Controls packaging line routing flaps during high-pressure washdown cycles, where the stainless steel rod prevents corrosion and pitting.
Bottling Line Gate
Operates 35 mm short-stroke sorting gates on a beverage bottling line, delivering rapid 30-800 mm/s cycling to handle high-throughput container traffic.
Is the Airtac SE63 Standard Cylinder SE63AX35 the Right Cylinder?
This 63 mm bore provides 1559 N push at 0.5 MPa. If your application requires less force, the 50 mm bore offers 982 N push; if you need more power, stepping up to the 80 mm bore yields 2513 N push. Because this is a double-acting cylinder, it relies on live air pressure to move and hold its position—if air is lost or the valve is centered, the piston will drift and cannot hold a load. For secure position holding, consider the BSE rod-lock variant.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other ISO 15552 cylinders, sharing standard mounting accessories like FA front flanges or LB foot brackets. The PT3/8 port and M16x1.5 rod-end thread match the standardized 63 mm footprint. Since the stroke is only 35 mm, side-load stress on the rod bearing is minimal, though an external guide is always recommended for heavy lateral loads.
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 SE63 Standard Cylinder SE63AX35 FAQ
At 0.5 MPa, the SE63AX35 provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N. The absolute maximum push force is 318 kgf at 1.0 MPa.
No, this specific SKU does not include a built-in magnet (indicated by the absence of the -S option code), meaning it cannot support AirTAC CMSE reed or DMSE electronic sensors. You would need the SE63SX35 variant for position sensing.
