About the Airtac SE50 Standard Cylinder SE50AX145S
The AirTAC SE50AX145S is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding washdown and corrosive environments. Equipped with a SUS420J2 stainless steel piston rod (code A), it delivers a robust 982 N push force at 0.5 MPa alongside an 825 N pull force. The square extruded aluminum barrel omits external tie rods, yielding a compact, flush-mounting body that naturally resists mechanical snagging and surface corrosion.
This 50 mm bore unit features a built-in magnet (code S) for seamless integration with AirTAC CMSE reed and DMSE electronic position sensors. Field-adjustable pneumatic cushioning at both stroke ends allows technicians to fine-tune end-of-travel deceleration via a set screw, effectively neutralizing hard mechanical impacts when cycling at speeds up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50AX145S Is Used
Form-Fill-Seal Jaw Actuation
Drives the primary sealing jaws on vertical form-fill-seal machinery, using its 982 N thrust and 145 mm stroke to crimp pouches reliably in damp washdown environments.
Stainless Steel Conveyor Diverter
Pushes product lanes on food-grade conveyors, where the SUS420J2 rod resists daily chemical washdowns and the 145 mm stroke cleanly routes packages between processing belts.
Lab Sample Centrifuge Loader
Indexs sample racks into laboratory centrifuge chambers, leveraging the flush no-tie-rod profile to prevent dirt traps while the -S magnet triggers DMSE sensors for precise positioning.
Is the Airtac SE50 Standard Cylinder SE50AX145S the Right Cylinder?
When sizing this 145 mm stroke actuator, compare its 982 N push at 0.5 MPa against neighboring bores: step down to a 40 mm bore for 628 N, or step up to a 63 mm bore for 1559 N if your payload demands greater thrust. Because this is a standard double-acting cylinder, it cannot hold a load dynamically if air pressure drops or the valve centers; for dead-load holding, pivot to the BSE rod-lock variant. Furthermore, at 145 mm of travel, the M16x1.5 threaded rod handles moderate side loads, but for heavy off-center loads, an external guide rail is recommended to prevent rod-bearing bending.
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 SE50AX145S FAQ
