About the Airtac SE50 Standard Cylinder SE50AX275S
The AirTAC SE50AX275S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and a 275 mm stroke. It generates 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa, utilizing a PT1/4 port and a 20 mm rod with an M16x1.5 thread. The square extruded aluminum barrel omits external tie rods, yielding a flush, corrosion-resistant body that simplifies mounting and reduces contamination traps in tight machinery layouts.
This specific configuration features a SUS420J2 stainless steel rod (code A) for corrosive or washdown environments, and includes a built-in magnet (code S) for position sensing. The integrated magnet interfaces seamlessly with AirTAC CMSE reed and DMSE electronic sensors dropped into the three-sided sensor grooves. Furthermore, the field-adjustable pneumatic cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling.

Where the Airtac SE50 Standard Cylinder SE50AX275S Is Used
Flow Wrapper End-Seal Jaw
Drives the rotary or box-motion sealing jaw on a continuous flow wrapper, using the 982 N force and 275 mm stroke to cleanly cut and seal packaging film in damp food-grade environments relying on the SUS420J2 rod.
Bottling Line Diverter Gate
Actuates a high-speed diverter arm on an automated bottling line to reject or route containers, utilizing the integrated magnet and DMSE sensors for precise positioning at up to 800 mm/s.
Lab Washdown Dispense Head
Positions a fluid dispense nozzle over a multi-well processing plate in a life-science washdown station, benefiting from the flush tie-rod-free barrel exterior that prevents chemical pooling.
Is the Airtac SE50 Standard Cylinder SE50AX275S the Right Cylinder?
When sizing this 50 mm bore actuator, evaluate your load against the 982 N push at 0.5 MPa. If your application requires less force, stepping down to the 40 mm bore drops the 0.5 MPa push to 628 N, whereas upgrading to the 63 mm bore raises it to 1559 N. Because the 275 mm stroke exceeds 300 mm threshold considerations, ensure the unsupported rod bearing does not suffer excessive bending under heavy lateral loads; integrating an external guide rail is strongly recommended to prevent premature seal wear.
As a true ISO 15552 profile cylinder, the SE50AX275S serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standard mounting accessories like FA front flanges or LB foot brackets. Remember that the adjustable air cushion only decelerates the piston near stroke end; it does not lock or hold the load. If your process requires true position holding upon air loss or valve centering, you must pivot to the AirTAC BSE rod-lock variant or employ an external pilot-operated check valve.
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.
