About the Airtac SE63 Standard Cylinder SE63AX250
The AirTAC SE63AX250 is a double-acting single-rod ISO 15552 profile cylinder engineered for demanding 250 mm stroke applications. It delivers a robust 1559 N push force at 0.5 MPa, utilizing a 63 mm bore and a PT3/8 port. This specific SKU features an SUS420J2 stainless steel rod (code A), making it highly suitable for corrosive or washdown environments where a standard carbon steel rod would fail.
Built with a square extruded aluminum barrel free of external tie rods, the body is exceptionally compact and easy to mount flush against machinery. The cylinder incorporates field-adjustable air cushioning at both ends, allowing technicians to precisely tune end-of-stroke deceleration and eliminate hard impacts. Note that this configuration does not include a position-sensing magnet, so external limit switches are required if electronic CMSE or DMSE sensors are not needed.

Where the Airtac SE63 Standard Cylinder SE63AX250 Is Used
Stainless Rod Palletizer
Drives the lift arm in a washdown palletizing cell, using the 1559 N push force to elevate heavy product stacks while the SUS420J2 rod shrugs off daily chemical cleanings.
Divert Gate Actuator
Powers a 250 mm stroke sorting diverter on a food-grade conveyor, relying on the field-adjustable pneumatic cushioning to soften the gate impact at high cycling speeds.
CNC Lathe Unloader
Ejects finished metal rings from a CNC lathe, where the no-tie-rod extruded profile allows the cylinder to mount flush into the tight machine cavity without obstruction.
Is the Airtac SE63 Standard Cylinder SE63AX250 the Right Cylinder?
When sizing this actuator, evaluate your force requirements against its 1559 N push at 0.5 MPa. If your application demands less force, stepping down to the 50 mm bore yields 982 N push, saving space and air consumption. Conversely, if you need higher thrust, stepping up to the 80 mm bore provides 2513 N push. At a 250 mm stroke, the 20 mm rod and M16x1.5 thread provide good rigidity, but you must verify the rod-bearing bending loads; for heavy side-mounted loads, an external guide rail is strongly recommended to prevent premature seal wear.
This SE profile cylinder is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 cylinders using identical mounting hardware. Because it lacks a rod lock mechanism, it cannot hold a load if air pressure is lost or the valve is centered—the piston will drift. For position-holding safety, consider the AirTAC BSE series or an external pilot-operated check valve.
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 SE63AX250 FAQ
The SE63AX250 generates a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. At 0.7 MPa, the push force increases to 2182 N. The maximum allowable push force is 318 kgf at 1.0 MPa.
Yes, the SE63AX250 is dimensionally interchangeable per ISO 15552 standards. You can use it as a direct replacement for other ISO 15552 profile cylinders, reusing the exact same mounting footprint and port locations (PT3/8) without redesigning your machine plates.
