About the Airtac SE50 Standard Cylinder SE50AX225S
The AirTAC SE50AX225S is a double-acting, single-rod ISO 15552 profile cylinder engineered for rigorous washdown environments. Featuring a 50 mm bore and a 225 mm stroke, it provides a robust 982 N push force at 0.5 MPa alongside an 825 N pull force. The SUS420J2 stainless steel rod (code A) directly resists corrosion and chemical exposure, making it ideal for food processing or pharmaceutical machinery where standard carbon steel rods degrade prematurely.
This model incorporates a built-in magnet (code S) for seamless integration with AirTAC CMSE reed and DMSE electronic position sensors. The extruded aluminum barrel omits external tie rods, yielding a compact, flush-mount profile that prevents dirt accumulation and simplifies sensor placement along three distinct grooves. Furthermore, the field-adjustable pneumatic cushioning at both ends allows technicians to precisely tune end-of-stroke deceleration, softening hard mechanical stops during high-speed actuation.

Where the Airtac SE50 Standard Cylinder SE50AX225S Is Used
Pharmaceutical Skid Clamping
Leveraging the SUS420J2 stainless rod and 982 N push force to securely clamp reaction vessels on CIP washdown skids without rod degradation.
Packaging Line Diverting
Actuating stainless steel diverters across a 225 mm stroke to redirect cartons on a washdown-ready packaging conveyor at up to 800 mm/s.
CNC Fixture Positioning
Moving protective doors or workholding fixtures on CNC mills, utilizing the built-in magnet with DMSE sensors for precise end-position verification.
Is the Airtac SE50 Standard Cylinder SE50AX225S the Right Cylinder?
When sizing this actuator, compare its 982 N push against the adjacent bores: step down to a 40 mm bore for 628 N of push, or step up to a 63 mm bore for 1559 N to handle heavier loads. Because this 225 mm stroke exceeds 300 mm, no external guide is strictly mandated for side-load support, but the M16x1.5 rod thread and 20 mm rod diameter handle moderate lateral stresses well. As a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standardized mounting hardware. Note that this plain SE cylinder does not hold its position if air pressure is lost; if your process requires static load holding during air failure, consider the BSE rod lock variant.
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.
