About the Airtac SE50 Standard Cylinder SE50AX165S
The AirTAC SE50AX165S is a double-acting, single-rod ISO 15552 profile cylinder engineered for 165 mm stroke applications. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while protecting internal mechanics.
This specific configuration integrates a SUS420J2 stainless steel rod (code A) for superior resistance to moisture and washdown chemicals. A built-in magnet (-S) enables seamless position detection with AirTAC CMSE reed or DMSE electronic sensors. Furthermore, the field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed 30-800 mm/s operations.

Where the Airtac SE50 Standard Cylinder SE50AX165S Is Used
Flow Wrapper Sealing Jaw
Drives the 165 mm stroke sealing jaw on horizontal flow wrappers, utilizing the 982 N push force and SUS420J2 rod to withstand washdown cycles in food packaging facilities.
Pallet Divert Arm
Actuates 50 mm bore diverting gates on inline pallet conveyors, relying on the built-in magnet for DMSE sensor feedback to confirm package routing.
Lab Sample Ejector
Pushes processed test cartridges out of analytical instruments, where the corrosion-resistant SUS420J2 rod prevents contamination from reagent exposure.
Is the Airtac SE50 Standard Cylinder SE50AX165S the Right Cylinder?
Delivering 982 N push at 0.5 MPa, this 50 mm bore fits neatly between the 40 mm bore (628 N push) and the 63 mm bore (1559 N push), allowing you to scale up or down depending on your exact payload. As a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for any compliant ISO 15552 unit, utilizing a PT1/4 port, M16x1.5 rod thread, and standard mounting accessories. Note that while the adjustable end cushions soften stroke transitions, a plain SE cylinder cannot hold a load if air pressure drops; for static holding, consider the BSE rod lock variant. At 165 mm stroke, side loads are moderate, but always verify rod-bearing bending limits and use an external guide for heavy offset loads.
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 SE50AX165S FAQ
At 0.5 MPa, the SE50AX165S provides 982 N push and 825 N pull. At 0.7 MPa, push increases to 1374 N, with a maximum push of 200 kgf at 1.0 MPa. The operational speed ranges from 30-800 mm/s.
Yes, the SE50AX165S is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting footprint, PT1/4 port, and M16x1.5 rod thread of other standard ISO 15552 profile cylinders for easy retrofits.
