About the Airtac SE50 Standard Cylinder SE50AX140
The AirTAC SE50AX140 is a double-acting, single-rod ISO 15552 profile cylinder engineered to deliver 982 N of push force and 825 N of pull force at 0.5 MPa. It features a 50 mm bore, a 140 mm stroke, and a SUS420J2 stainless steel rod (option A) specifically designed to resist corrosion in washdown or chemically harsh environments.
Unlike traditional tie-rod designs, its extruded aluminum barrel lacks external protruding rods, yielding a compact footprint that mounts flush against machine frames. The cylinder includes field-adjustable pneumatic cushioning at both ends, allowing technicians to tune end-of-stroke deceleration via a set screw to eliminate hard mechanical impacts during high-speed cycling.

Where the Airtac SE50 Standard Cylinder SE50AX140 Is Used
Flow Wrapper Film Sealing
Drives the sealing jaw on stainless food-grade flow wrappers, utilizing the 982 N push force to cut and seal packaging film cleanly while withstanding daily washdowns.
Bottling Line Diverter
Actuates a routing gate on a high-speed beverage bottling conveyor, where the SUS420J2 rod resists moisture and the 140 mm stroke provides precise lane switching.
Lab Sample Dispenser
Positions fluid dispensing nozzles in chemical analysis equipment, benefiting from the corrosion-resistant rod and adjustable end cushions to prevent test tube breakage.
Is the Airtac SE50 Standard Cylinder SE50AX140 the Right Cylinder?
This 50 mm bore generates 982 N push at 0.5 MPa. If your application requires less force, the 40 mm bore provides 628 N push; if you need substantially more thrust, stepping up to the 63 mm bore yields 1559 N push. Because this specific SKU lacks the -S magnet code, it cannot host AirTAC CMSE or DMSE position sensors without modification—confirm if automated end-of-stroke signaling is required for your control system.
As a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing identical mounting interface dimensions and port sizing (PT1/4). Note that the integrated air cushion only decelerates the piston near stroke end; it cannot hold a load vertically if air pressure is lost. For position holding, a BSE rod lock variant or external check valve is required.
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 SE50AX140 FAQ
At 0.5 MPa, the SE50AX140 provides 982 N push and 825 N pull force. At 0.7 MPa, push increases to 1374 N. The maximum push force is 200 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, with a speed range of 30-800 mm/s.
Yes. The SE50AX140 is dimensionally interchangeable per ISO 15552 standards, meaning it shares identical mounting footprint and PT1/4 port locations with other ISO 15552 profile cylinders, allowing for seamless retrofits without machine modifications.
