About the Airtac SE50 Standard Cylinder SE50AX40S
The AirTAC SE50AX40S is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding washdown and corrosive environments. By specifying the A option code, this unit features a SUS420J2 stainless steel piston rod that resists rust and chemical degradation far better than standard carbon steel. It delivers a robust 982 N push force at 0.5 MPa alongside 825 N of pull force, making it highly effective for compact, high-cycle actuation tasks.
Unlike traditional tie-rod designs, the SE series utilizes a square extruded aluminum barrel that completely eliminates external tie rods. This profile not only prevents debris buildup around the cylinder body but also allows for flush mounting in tight machinery spaces. Furthermore, the integrated S magnet enables seamless position detection with AirTAC CMSE reed or DMSE electronic sensors along the body's three dedicated sensor grooves.

Where the Airtac SE50 Standard Cylinder SE50AX40S Is Used
Flow Wrapper End-Seal Jaw
Drives the 40 mm stroke end-seal cutting jaw on a continuous flow wrapper, utilizing the 982 N push force at 0.5 MPa to cleanly sever packaging film in washdown environments.
Lab Sample Dispenser
Actuates a 50 mm bore dosing valve for chemical sample dispensing, relying on the SUS420J2 stainless steel rod to prevent corrosion from aggressive solvent splashes.
PCB Router Clamp
Secures printed circuit boards during robotic routing operations, using the built-in S magnet and DMSE electronic sensors to confirm clamp engagement within the 40 mm stroke.
Is the Airtac SE50 Standard Cylinder SE50AX40S the Right Cylinder?
When sizing this actuator, stepping down to a 40 mm bore yields 628 N of push at 0.5 MPa, while stepping up to a 63 mm bore provides 1559 N of push at 0.5 MPa, giving you clear scaling options around the 50 mm platform. Since the stroke is 40 mm, side-load stress on the rod bearing is minimal, though any application requiring load holding without continuous air pressure will need an external pilot-operated check valve or a BSE rod lock variant, as the SE50AX40S drifts when air is lost. For retrofitting, this cylinder is dimensionally interchangeable per ISO 15552 standards, sharing identical mounting footprints and PT1/4 port locations with comparable profile cylinders.
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 SE50AX40S FAQ
The SE50AX40S delivers 982 N of push force and 825 N of pull force at 0.5 MPa, and 1374 N of push force at 0.7 MPa. Its maximum push force is 200 kgf at 1.0 MPa. The cylinder features a PT1/4 port and a 20 mm diameter SUS420J2 stainless steel rod.
No, the SE50AX40S is a double-acting cylinder that drifts when air pressure is lost or a valve is centered. The field-adjustable air cushions at both ends only decelerate the piston near the stroke limits; they do not lock or hold the load. For position holding, consider an AirTAC BSE rod lock variant or an external pilot-operated check valve.
