Airtac SE50 Standard Cylinder SE50AX450
The AirTAC Airtac SE50 Standard Cylinder SE50AX450 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø50mm bore and 450mm stroke, PT1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE50 Standard Cylinder SE50AX450
The AirTAC SE50AX450 is a double-acting, single-rod ISO 15552 profile cylinder with a 50 mm bore and 450 mm stroke. It delivers a robust 982 N push force at 0.5 MPa and features a SUS420J2 stainless steel rod (code A) engineered for corrosive or washdown environments. The extruded aluminum barrel omits external tie rods, yielding a compact, flush-mounting body that resists debris buildup.
This model integrates field-adjustable pneumatic cushioning at both ends to decelerate the piston near the stroke limits, softening hard end stops during high-speed cycling. Operating at 30-800 mm/s, it uses a PT1/4 port and an M16x1.5 rod thread. Note that this specific SKU lacks a built-in magnet, so it will not trigger AirTAC CMSE or DMSE position sensors without modification.

Where the Airtac SE50 Standard Cylinder SE50AX450 Is Used
Vertical Pouch Sealing
Drives the sealing jaw on a vertical form-fill-seal machine, using the 450 mm stroke to accommodate tall packaging formats while the SUS420J2 rod withstands daily washdowns.
Bottle Diverting
Actuates a routing gate on a stainless steel conveyor line, providing 982 N of push force to reliably redirect heavy beverage containers without hesitation.
Lab Sample Ejection
Ejects processed sample trays from a chemical analyzer, where the SUS420J2 rod material prevents corrosion from accidental reagent exposure.
Is the Airtac SE50 Standard Cylinder SE50AX450 the Right Cylinder?
Delivering 982 N push at 0.5 MPa, this 50 mm bore cylinder sits between the 40 mm bore (628 N push) and the 63 mm bore (1559 N push), allowing you to step down for lighter loads or up for higher thrust. Because the stroke is 450 mm, the unsupported piston rod is subject to bending under lateral loads; integrating an external guide rail is strongly recommended to prevent premature rod-bearing wear. As a true ISO 15552 profile cylinder, it provides a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standard mounting accessories like FA or LB brackets. Remember that a standard SE cylinder does not hold its position when air is exhausted or a valve is centered—the piston drifts—so apply a BSE rod lock for fail-safe load holding.
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 SE50AX450 FAQ
At 0.5 MPa, the SE50AX450 provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N. The maximum push force is 200 kgf at the maximum operating pressure of 1.0 MPa.
This specific SKU does not include a built-in magnet, so it cannot directly trigger AirTAC CMSE or DMSE position sensors. If electronic or reed switch feedback is required for your application, you would need to specify the -S magnet option on your cylinder order.
