About the Airtac SE63 Standard Cylinder SE63AX300S
The AirTAC SE63AX300S is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding 300 mm stroke applications. It delivers a robust 1559 N push force at 0.5 MPa and 2182 N at 0.7 MPa, utilizing a 36 mm adjustable air cushion at both ends to smooth out high-speed end-of-stroke impacts. Equipped with a SUS420J2 stainless steel rod, it is purpose-built for corrosive or washdown environments where standard carbon steel rods would fail.
Because the barrel is an extruded aluminum profile without external tie rods, the body is inherently compact and corrosion-resistant, allowing flush mounting on machinery frames. The built-in magnet (-S) seamlessly interfaces with AirTAC CMSE reed and DMSE electronic sensors, which seat directly into the sensor grooves on three sides of the body for flexible positioning. This cylinder is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders without requiring custom mounting hardware.

Where the Airtac SE63 Standard Cylinder SE63AX300S Is Used
Food Packaging Diverter
The SUS420J2 stainless rod withstands daily washdown chemicals while providing 1559 N of push force to actuate large flap gates routing product into cartons.
Pallet Stopper Arm
Using the 300 mm stroke to extend a physical barrier, this cylinder halts heavy wooden pallets on a transfer line, absorbing kinetic energy via its adjustable cushions.
Lab Filtration Press
DMSE electronic sensors track the full 300 mm extension precisely, ensuring consistent compaction of filter media while resisting humidity in chemical processing areas.
Is the Airtac SE63 Standard Cylinder SE63AX300S the Right Cylinder?
If your application requires less force, the next bore down is 50 mm, which provides 982 N of push force at 0.5 MPa. If you need to scale up, the 80 mm bore yields 2513 N at 0.5 MPa. At a 300 mm stroke, the 20 mm rod and M16x1.5 thread experience increased bending moments under heavy lateral loads; an external guide rail is strongly recommended to prevent rod-bearing wear and premature seal failure. Remember that a plain SE cylinder does not hold its position or load when air is lost or the valve is centered—the piston will drift—so for fail-safe load holding, look to the BSE rod lock variant. To match this exact ISO 15552 footprint, specify the 63 mm bore, 300 mm stroke, PT3/8 port, your required mounting accessory, and the -S magnet.
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 SE63AX300S FAQ
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. At 0.7 MPa, the push force increases to 2182 N. The maximum push force is 318 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No. The adjustable air cushion only decelerates the piston near the stroke ends and is not a locking brake. If air is lost or the valve is centered, the piston will drift. For fail-safe load holding, you need a BSE series rod lock cylinder or an external pilot-operated check valve.
