About the Airtac SE50 Standard Cylinder SE50AX190
The AirTAC SE50AX190 is a double-acting single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and 190 mm stroke. It delivers a robust 982 N push force at 0.5 MPa, utilizing a PT1/4 port and a 20 mm piston rod threaded M16x1.5. This unit features a SUS420J2 stainless steel rod (code A), making it highly suitable for corrosive environments or washdown duty where standard carbon steel would fail.
The extruded aluminum barrel design omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion. Field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling. Note that this specific SKU lacks a built-in magnet, so it does not support CMSE or DMSE electronic position sensing without modification.

Where the Airtac SE50 Standard Cylinder SE50AX190 Is Used
Bottle Rinser Gripper
Utilizes the SUS420J2 stainless rod to withstand wet washdown conditions while actuating gripper arms that invert and rinse beverage containers on a high-speed line.
Carton Flap Folder
Employs the 982 N push force at 0.5 MPa to reliably fold heavy corrugated cardboard flaps prior to sealing, with adjustable cushioning softening the stroke end.
Metal Stamping Ejector
Leverages the 190 mm stroke to push stamped sheet metal parts clear of a press die, benefiting from the flush-mount profile barrel to fit tight tooling spaces.
Is the Airtac SE50 Standard Cylinder SE50AX190 the Right Cylinder?
Selecting this 50 mm bore cylinder makes sense when your application requires 982 N of push force at 0.5 MPa. If you need less force and a smaller footprint, step down to the 40 mm bore, which provides 628 N of push at 0.5 MPa. Conversely, if your load demands more power, stepping up to the 63 mm bore yields 1559 N of push at 0.5 MPa. Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; the piston will drift. For position-holding requirements, consider the BSE rod-lock variant. With a 190 mm stroke, the unsupported load should be guided externally to prevent rod-bearing bending and premature seal wear. This model is dimensionally interchangeable with other ISO 15552 profile cylinders, simplifying retrofits.
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 SE50AX190 FAQ
The SE50AX190 generates 982 N of push force and 825 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and cycles at speeds between 30-800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552 standards, allowing it to drop into existing footprints using standard mounting hardware. However, as a standard double-acting cylinder, it does not hold its position if air is lost; you would need an AirTAC BSE rod lock cylinder for that function.
