About the Airtac SE63 Standard Cylinder SE63AX120
The AirTAC SE63AX120 is a double-acting, single-rod ISO 15552 profile cylinder featuring a 63 mm bore and 120 mm stroke. It delivers a robust 1559 N push force at 0.5 MPa, utilizing a PT3/8 port and a 36 mm adjustable cushion length. This specific SKU is configured with a SUS420J2 stainless steel rod (code A), making it highly suitable for corrosive or washdown environments where a standard medium-carbon steel rod would fail.
The extruded aluminum barrel design omits external tie rods, yielding a compact, smooth body that is easy to mount flush against machine frames while resisting debris buildup. Unlike fixed rubber bumpers, this cylinder features a field-adjustable pneumatic cushion at both ends, allowing technicians to tune end-stop deceleration via a screw to soften hard impacts at high speeds. Note that this specific unit lacks a built-in magnet, meaning it is not equipped for AirTAC CMSE or DMSE position sensing out of the box.

Where the Airtac SE63 Standard Cylinder SE63AX120 Is Used
Corrosive-Resistant Palletizer
Ideal for driving push-off arms in washdown packaging lines, utilizing its 1559 N push force and SUS420J2 stainless rod to withstand daily chemical sanitation.
Food Processing Diverters
Perfect for actuating flow diverters in food-grade fluid handling, where the smooth, tie-rod-free extruded profile prevents bacterial traps.
Bottling Line Cappers
Provides reliable 120 mm stroke capping torque and retraction in humid bottling environments, benefiting from the field-adjustable end cushions to protect cap alignment.
Is the Airtac SE63 Standard Cylinder SE63AX120 the Right Cylinder?
When sizing this 63 mm bore, consider stepping down to a 50 mm bore if your application requires less force, as the 50 mm provides 982 N of push at 0.5 MPa. Conversely, if your load demands more thrust, stepping up to an 80 mm bore yields 2513 N of push at 0.5 MPa. Because this is a double-acting cylinder, it relies on continuous air pressure to maintain position; if your process requires holding a load without live pressure, you must integrate an external pilot-operated check valve or transition to the AirTAC BSE rod-lock variant. The 120 mm stroke is well below the 1500 mm maximum standard stroke, keeping side-load stress on the M16x1.5 rod thread manageable without needing an external guide.
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 SE63AX120 FAQ
The SE63AX120 generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 2182 N, with an absolute maximum push of 318 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders using standard mounting hardware. However, this specific SKU does not include a built-in magnet (-S), so it cannot support AirTAC CMSE or DMSE electronic position sensors without modification.
