About the Airtac SE63 Standard Cylinder SE63AX125
The AirTAC SE63AX125 is a double-acting, single-rod ISO 15552 profile cylinder delivering a robust 1559 N push force at 0.5 MPa. It features a 63 mm bore and a 125 mm stroke, utilizing a PT3/8 port for optimal airflow. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion.
This specific SKU is configured with a SUS420J2 stainless steel rod (option A) for corrosive and washdown environments. It lacks the built-in magnet option, meaning CMSE or DMSE electronic position sensors cannot be fitted to this unit without modification. Field-adjustable pneumatic cushioning at both end caps allows technicians to dial in end-of-stroke deceleration, softening hard mechanical stops during high-speed cycling.

Where the Airtac SE63 Standard Cylinder SE63AX125 Is Used
Stainless Food Processing
Ideal for washdown stations pushing 1559 N at 0.5 MPa, where the SUS420J2 rod resists moisture and cleaning chemicals better than standard carbon steel.
Packaging Line Diverter
Handles package redirecting tasks using its 125 mm stroke, relying on the adjustable end cushions to silently absorb kinetic energy during rapid 30-800 mm/s cycling.
CNC Chuck Actuation
Provides reliable clamping force on machining centers, utilizing the corrosion-resistant rod to endure coolant splash while maintaining a flush, tie-rod-free profile.
Is the Airtac SE63 Standard Cylinder SE63AX125 the Right Cylinder?
When sizing this 63 mm bore, stepping down to the 50 mm bore reduces your 0.5 MPa push force to 982 N, while stepping up to the 80 mm bore increases it to 2513 N. Because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops or the valve is centered; for position holding, you would need a BSE rod lock variant. As a true ISO 15552 profile cylinder, it serves as a direct dimensional replacement sharing standard mounting hardware. Note that this SKU omits the sensor magnet (-S) and uses a PT3/8 port.
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 SE63AX125 FAQ
The SE63AX125 generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. At 0.7 MPa, the push force is 2182 N, with a maximum push capacity of 318 kgf at 1.0 MPa. It uses a PT3/8 port and features a 20 mm diameter SUS420J2 stainless steel rod.
Yes, the SE63AX125 is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting footprint and can serve as a direct replacement for other ISO 15552 profile cylinders using standard LB, FA, or TC mounting accessories.
