About the Airtac SE50 Standard Cylinder SE50AX325S
The AirTAC SE50AX325S is a double-acting, single-rod ISO 15552 profile cylinder featuring a 50 mm bore and a 325 mm stroke. Because the stroke exceeds the 1200 mm standard maximum, this specific 325 mm length is classified as a non-standard, made-to-order stroke. It delivers a robust 982 N push force at 0.5 MPa and 1374 N at 0.7 MPa. The SUS420J2 stainless steel rod (code A) provides enhanced corrosion resistance for washdown or humid environments.
This unit includes 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-mounting profile that resists corrosion and simplifies sensor placement along three dedicated grooves. Furthermore, the field-adjustable pneumatic cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration, softening hard impacts during high-speed operation.

Where the Airtac SE50 Standard Cylinder SE50AX325S Is Used
Pouch Forming Cutoff
Actuates the sealing blade on vertical form-fill-seal equipment, using the 982 N push force and 325 mm stroke to cleanly cut heavy laminate films in damp environments.
Bottle Diverter Gate
Drives a sorting arm on a bottling line to route containers, relying on the SUS420J2 stainless rod to withstand frequent washdowns without rusting.
Press Brake Ejection
Ejects formed sheet metal parts from a press brake, utilizing the DMSE electronic sensor to confirm full retraction before the next cycle begins.
Is the Airtac SE50 Standard Cylinder SE50AX325S the Right Cylinder?
This 50 mm bore yields 982 N push and 825 N pull at 0.5 MPa. If your application requires less force, the 40 mm neighbor provides 628 N push, whereas stepping up to the 63 mm bore increases output to 1559 N. Because the 325 mm stroke is non-standard, expect a made-to-order lead time. As a drop-in ISO 15552 replacement, it shares standard mounting dimensions and port sizes (PT1/4) with comparable cylinders.
With a 325 mm stroke, the 20 mm rod and its bearing are subjected to higher bending moments under side loads. For optimal longevity, use an external guide rail to prevent rod deflection. Note that this standard SE cylinder does not hold its position when air is lost; the piston will drift. For load-holding without live pressure, 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.
Airtac SE50 Standard Cylinder SE50AX325S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, the push force reaches 1374 N. The maximum push force is 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE50AX325S is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact same mounting footprint, port size (PT1/4), and rod-end thread (M16x1.5) as other standard profile cylinders. The built-in magnet also works directly with AirTAC CMSE and DMSE sensors.
