About the Airtac SAI50 Standard Cylinder SAI50BX450S
The AirTAC SAI50X450-S is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 982 N at 0.5 MPa and a pull force of 825 N. With a 450 mm stroke, it provides the extended travel necessary for packaging equipment and automated material handling. The extruded aluminum barrel design omits tie rods, offering a clean exterior that integrates seamlessly into modern machinery.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. It features PT tapered port threads and a built-in magnet (-S) that enables direct mounting of CMSE or DMSE solid-state sensors along the dual side grooves. You can also customize the seals with Viton (H) if your application involves elevated ambient temperatures.

Where the Airtac SAI50 Standard Cylinder SAI50BX450S Is Used
Long-Travel Pushing
Drives products smoothly down extended packaging lines or sorting chutes where a 450 mm reach is required to clear downstream obstructions.
Pallet Handling
Actuates diverter arms and lifting stops in distribution centers, utilizing the 982 N push force to redirect heavy totes reliably.
Component Ejection
Ejects molded or machined parts from machinery, relying on the SUS304 rod to withstand occasional coolant spray and humid plant conditions.
Is the Airtac SAI50 Standard Cylinder SAI50BX450S the Right Cylinder?
Choosing this 50 mm bore makes sense when a 40 mm bore (providing 628 N at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (delivering 2513 N) would be physically oversized. For a 450 mm stroke, side loads are a primary concern; an unsupported piston rod can bend under lateral stress. Mounting an external guide rail or utilizing a guided cylinder module is strongly recommended to protect the rod bearing and prevent premature wear.
As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders, allowing a direct replacement using standard FA/FB flange or TC trunnion accessories. Note that the adjustable air cushions at both ends only decelerate the piston near stroke limits; they do not hold a load. If pressure drops, the rod drifts—use the SAIL variant or an external rod lock for secure position holding.
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 SAI50BX450S FAQ
