About the Airtac SE50 Standard Cylinder SE50AX210S
The AirTAC SE50AX210S is a double-acting single-rod ISO 15552 profile cylinder delivering a 982 N push force at 0.5 MPa. It features a 50 mm bore, 210 mm stroke, and a SUS420J2 stainless steel rod (code A) engineered for corrosive or washdown environments. The square extruded aluminum barrel removes external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting external corrosion.
Equipped with a built-in magnet (code S), this unit supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable air cushion at both ends lets technicians tune end-stop deceleration via a setscrew, softening impacts at high cycling speeds without relying on fixed rubber bumpers.

Where the Airtac SE50 Standard Cylinder SE50AX210S Is Used
Flow Wrapper End-Sealing
Provides 982 N of push force at 0.5 MPa to actuate the mechanical crimping jaws on horizontal flow wrappers, with the SUS420J2 rod enduring periodic washdowns.
Log Transfer Diverter
Utilizes the 210 mm stroke to swing a diverter arm across a conveyor lane, redirecting packaged cartons to secondary packaging lines without stalling.
Lab Sample Centrifuge Gate
Leverages the DMSE electronic sensor compatibility and corrosion-resistant stainless steel rod to safely open and close access doors on high-speed lab centrifuges.
Is the Airtac SE50 Standard Cylinder SE50AX210S the Right Cylinder?
At 0.5 MPa, this 50 mm bore generates 982 N of push force. If your application requires less force, stepping down to the 40 mm bore yields 628 N, whereas moving up to the 63 mm bore provides 1559 N for heavier payloads. Because the 210 mm stroke exceeds the 300 mm threshold, the unsupported piston rod is susceptible to bending under side loads; always utilize an external guide rail to prevent premature bearing wear.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 profile cylinders, sharing standardized mounting hardware like FA front flanges or LB foot brackets. Note that a plain SE cylinder will drift if air pressure is lost or the valve centers; for position holding, consider the BSE rod lock variant.
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 SE50AX210S FAQ
The SE50AX210S generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum of 200 kgf at 1.0 MPa. It uses a PT1/4 port, a 20 mm rod diameter, and an M16x1.5 rod-end thread.
No, the field-adjustable air cushion only decelerates the piston near the stroke ends and is not a locking mechanism. The cylinder will drift if air pressure is lost or the valve is centered; for holding vertical loads, use a BSE series rod lock cylinder or an external pilot-operated check valve.
