About the Airtac SE63 Standard Cylinder SE63AX45
The AirTAC SE63AX45 is a double-acting, single-rod ISO 15552 profile cylinder with a 63 mm bore and 45 mm stroke. It delivers a robust 1559 N of push force and 1402 N of pull force at 0.5 MPa, making it well-suited for mid-range industrial actuation. The extruded aluminum barrel features a square design without external tie rods, which keeps the body compact, corrosion-resistant, and easy to mount flush against machine frames.
This specific SKU is configured with a SUS420J2 stainless steel rod (option A) for enhanced corrosion and washdown resistance. The cylinder relies on a PT3/8 port and includes field-adjustable air cushioning at both ends, allowing technicians to tune the end-of-stroke deceleration via a set screw rather than relying on a fixed bumper. Note that this unit lacks a built-in magnet, so it is not wired for CMSE or DMSE position sensing out of the box.

Where the Airtac SE63 Standard Cylinder SE63AX45 Is Used
Vertical Carton Flap Folding
Provides the 1559 N push force required to consistently fold heavy cardboard carton flaps on continuous packaging lines, while the SUS420J2 rod resists washdown moisture.
Pallet Wood Straightening
Uses its 45 mm stroke to align wayward deck boards on automated pallet assembly machines before nailing, relying on adjustable cushions to soften hard end stops at speed.
Beverage Filler Gate Control
Actuates flow diversion gates in liquid filling stations, where the stainless steel rod endures frequent cleaning cycles and the square profile mounts flush to the frame.
Is the Airtac SE63 Standard Cylinder SE63AX45 the Right Cylinder?
If you are sizing this actuator, consider stepping down to the 50 mm bore (982 N push at 0.5 MPa) for lighter clamping tasks, or moving up to the 80 mm bore (2513 N push at 0.5 MPa) if your application requires heavier thrust. Because this is a standard double-acting cylinder, it will not hold a load in place if air pressure is lost or the valve is centered; the piston will drift. For position-holding needs, you would need the BSE rod-lock variant or an external pilot-operated check valve. As a true ISO 15552 profile cylinder, the SE63AX45 is dimensionally interchangeable with other ISO 15552 cylinders, allowing you to drop it into existing footprints and reuse standard FA or LB mounting hardware without redesigning your machine plates.
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 SE63AX45 FAQ
The SE63AX45 has a 63 mm bore and 45 mm stroke. At 0.5 MPa it provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa the push force is 2182 N, and the maximum push force is 318 kgf at 1.0 MPa. It uses a PT3/8 port, a Ø20 mm SUS420J2 stainless steel rod with an M16x1.5 thread, and operates at 30-800 mm/s.
Yes, the SE63AX45 is dimensionally interchangeable per ISO 15552 / VDMA 24562 standards. Its standardized mounting interface and dimensions allow it to serve as a direct replacement for other ISO 15552 profile cylinders, meaning you can reuse your existing mounting hardware and fixture spacing without modifications.
