About the Airtac SAI50 Standard Cylinder SAI50AX450S
The AirTAC SAI50X450-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa. Its 50 mm bore and 450 mm stroke make it well-suited for medium-duty automation tasks requiring substantial travel distance. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies the mounting of accessories.
This specific configuration includes a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance in humid environments. The -S suffix indicates a built-in magnet, allowing seamless integration with CMSE or DMSE reed switches via the sensor grooves machined into both sides of the barrel. It also features PT tapered port threads for a robust pneumatic seal.

Where the Airtac SAI50 Standard Cylinder SAI50AX450S Is Used
Material Ejection
Pushes products off a conveyor belt over a 450 mm gap with 982 N of force, utilizing the magnetic piston for end-of-stroke position confirmation.
Pallet Handling
Actuates pallet lifting gates or routing arms where the SUS420J2 rod resists moisture and the long stroke accommodates varying pallet sizes.
Door Automation
Opens and closes large industrial machine safety doors, relying on adjustable cushions to smoothly decelerate the 450 mm travel.
Is the Airtac SAI50 Standard Cylinder SAI50AX450S the Right Cylinder?
If your application requires less thrust, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, whereas moving up to a 63 mm bore provides 1559 N. Because this model features a 450 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, utilize an external guide rail or select a guided cylinder to absorb lateral forces.
This unit serves as a direct replacement for any ISO 15552 cylinder with a 50 mm bore, 450 mm stroke, PT G1/4 ports, and a matching mounting accessory like an FA flange or LB foot. Remember that the standard adjustable air cushions only decelerate the piston near stroke ends; they do not hold a load. If pressure drops, the rod will drift. For vertical loads requiring fail-safe holding, specify the SAIL variant with an air-released lock or an external pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI50 Standard Cylinder SAI50AX450S FAQ
At 0.5 MPa operating pressure, the SAI50X450-S provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X450-S is dimensionally interchangeable with other ISO 15552 profile cylinders. You can drop it into an existing 50 mm bore setup using the same G1/4 PT ports and ISO mounting accessories.
