About the Airtac SE50 Standard Cylinder SE50AX70S
The AirTAC SE50AX70S is a double-acting single-rod ISO 15552 profile cylinder engineered for 982 N push force at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while exposing standardized ISO 15552 dimensions for seamless retrofitting.
This 50 mm bore unit features a SUS420J2 stainless steel rod (code A) for corrosive or washdown environments, and includes a built-in magnet (code S) for non-invasive position sensing. Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed 30-800 mm/s cycles.

Where the Airtac SE50 Standard Cylinder SE50AX70S Is Used
Flow Wrapper Infeed
Drives the infeed pusher on a food-grade flow wrapper, utilizing the SUS420J2 stainless rod for washdown durability and 982 N push to index products precisely.
Diverter Gate Actuation
Pivots a routing flap on a packaging conveyor, using the built-in S magnet with DMSE sensors to confirm gate position before cartons arrive.
Lab Dispenser Valve
Actuates a metering valve in chemical processing equipment, where the SUS420J2 rod material resists mild corrosive exposure during frequent wash cycles.
Is the Airtac SE50 Standard Cylinder SE50AX70S the Right Cylinder?
Stepping down to a 40 mm bore drops the 0.5 MPa push output to 628 N, while moving up to a 63 mm bore increases it to 1559 N, allowing precise load matching. This SE50AX70S configuration is a direct dimensional replacement for other ISO 15552 cylinders, retaining the PT1/4 port, 70 mm stroke, and standard mounting hardware. Note that a plain SE cylinder cannot hold a load if air pressure is lost; for dead-end holding, consider the BSE rod lock variant. With a 70 mm stroke, side-load bending stress on the rod bearing is minimal, though external guides remain best practice for heavy offset loads.
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 SE50AX70S FAQ
The SE50AX70S delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum of 200 kgf at 1.0 MPa. The operating speed range is 30-800 mm/s.
Yes, the SE50AX70S is dimensionally interchangeable per ISO 15552 standards. It shares the exact mounting footprint, PT1/4 port, and M16x1.5 rod thread, allowing it to serve as a direct replacement for other ISO 15552 profile cylinders without altering the machine frame.
