About the Airtac SE50 Standard Cylinder SE50AX120S
The AirTAC SE50AX120S is a double-acting single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and a 120 mm stroke. It generates 982 N of push force at 0.5 MPa, utilizing a PT1/4 port and a 20 mm diameter piston rod. The extruded aluminum square barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This specific configuration features a SUS420J2 stainless steel rod (code A) for corrosive or washdown environments, and includes a built-in magnet (code S) for position sensing. The barrel integrates sensor grooves on three sides for flexible CMSE or DMSE switch mounting, while field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration and minimize impact shock.

Where the Airtac SE50 Standard Cylinder SE50AX120S Is Used
Flow Wrapper End-Seal
Drives the rotating sealing knife assembly on continuous flow wrappers, where the 982 N push force cleanly cuts and seals packaging film at high cycle rates.
Diverter Gate Actuator
Shifts routing flaps on modular conveyor lines, using the 120 mm stroke to redirect packages to specific packing lanes without stalling the belt.
Lab Washdown Station
Actuates cleaning nozzles in pharmaceutical washdown stations, leveraging the SUS420J2 stainless steel rod to withstand repeated exposure to harsh cleaning chemicals.
Is the Airtac SE50 Standard Cylinder SE50AX120S the Right Cylinder?
With a 982 N push at 0.5 MPa, this 50 mm bore fits mid-range actuation tasks. If you need less force, the 40 mm bore offers 628 N push; if your load demands more, stepping up to the 63 mm bore provides 1559 N push. Remember that a standard SE cylinder relies on live air pressure to move and will drift if air is lost or the valve is centered, so it cannot independently hold a load. For position holding without pressure, consider the BSE rod lock variant. Because this is a 120 mm stroke, side-load stress on the rod bearing is minimal, but always verify the load is guided. As a true ISO 15552 cylinder, it serves as a drop-in replacement sharing standard mounting dimensions and accessories.
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 SE50AX120S FAQ
