About the Airtac SE50 Standard Cylinder SE50AX550
The AirTAC SE50AX550 is a double-acting single-rod ISO 15552 profile cylinder featuring a 50 mm bore and 550 mm stroke. It delivers a robust 982 N push force at 0.5 MPa, utilizing a SUS420J2 stainless steel piston rod (code A) specifically designed for corrosive environments and washdown duty. The extruded aluminum barrel lacks external tie rods, creating a smooth, compact profile that resists debris buildup and mounts flush against machine frames.
Field-adjustable air cushions at both ends allow technicians to precisely tune end-of-stroke deceleration, preventing hard impacts during high-speed 30-800 mm/s operations. This SKU is manufactured without a position-sensing magnet, meaning no CMSE or DMSE switches can be fitted to this specific unit. The standardized ISO 15552 / VDMA 24562 mounting interface ensures exact dimensional interchangeability with other ISO 15552 cylinders, streamlining retrofits and procurement.

Where the Airtac SE50 Standard Cylinder SE50AX550 Is Used
Food Conveyor Diverter
Leveraging the 982 N push force and SUS420J2 stainless rod, this cylinder reliably actuates diverters on food processing lines where frequent washdowns would corrode standard carbon steel rods.
Palletizer Flap Control
The 550 mm stroke provides the extended travel needed to open and close large cardboard flap guides on automated palletizing machinery, ensuring precise box alignment.
Pharmaceutical Gate
With its smooth, tie-rod-free extruded profile preventing biological contamination, this unit operates washdown process gates in pharmaceutical batching equipment.
Is the Airtac SE50 Standard Cylinder SE50AX550 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 your load is lighter, stepping down to the 40 mm bore yields 628 N of push, whereas stepping up to the 63 mm bore provides 1559 N for heavier demands. The 550 mm stroke falls within the standard range, but at this length the unsupported mass of the piston rod increases the risk of side-load bending on the rod bearing; utilizing an external guide is strongly recommended to prevent premature wear.
Because this is a standard double-acting cylinder, it will drift if air pressure is lost or the valve is centered, as the air cushion only decelerates the piston near stroke end rather than locking the load. For position-holding safety, consider the BSE rod-lock variant. When replacing an existing ISO 15552 cylinder, verify the 50 mm bore, 550 mm stroke, PT1/4 port, and your required mounting accessory (such as an FA front flange or TC trunnion) to ensure a direct fit.
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 SE50AX550 FAQ
This 50 mm bore cylinder provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum push of 200 kgf at 1.0 MPa. It operates at speeds between 30-800 mm/s with a PT1/4 port and a 20 mm rod.
No, this specific SKU (SE50AX550) is configured without a built-in magnet, so CMSE reed and DMSE electronic sensors cannot be used. If position feedback is required, select the -S magnet option on your next order.
