About the Airtac SAI50 Standard Cylinder SAI50AX1000
The AirTAC SAI50X1000 is a double-acting ISO 15552 profile cylinder engineered for long-distance linear actuation. It provides a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for moving moderate loads over its 1000 mm stroke. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration utilizes a SUS420J2 stainless steel piston rod (material code A) for enhanced resistance to moisture and corrosion compared to standard carbon steel. It features PT tapered port threads and lacks a standard magnet; add the -S suffix if your application requires CMSE or DMSE sensor tracking along the dual-side barrel grooves.

Where the Airtac SAI50 Standard Cylinder SAI50AX1000 Is Used
Long-Stroke Material Transfer
Pushes workpieces or pallets across a 1000 mm gap between conveyor lines where a shorter stroke would require multiple stages.
High-Bay Shuttle Extraction
Extracts totes from deep storage racks, utilizing the 982 N push force to overcome sliding friction on heavily loaded bins.
Automated Door Actuation
Opens and closes large industrial partition doors or safety gates, benefiting from the SUS420J2 rod's resistance to humid environments.
Is the Airtac SAI50 Standard Cylinder SAI50AX1000 the Right Cylinder?
Selecting this 50 mm bore makes sense when a 40 mm bore (628 N push at 0.5 MPa) cannot overcome friction over a 1000 mm extension, yet an 80 mm bore (2513 N) would be physically oversized and consume excessive air. Because this model extends a full meter, the unsupported rod is highly susceptible to bending under side loads. You must use an external guide rail or a dedicated guided cylinder to prevent rod-bearing damage and premature seal wear.
This model serves as a dimensionally interchangeable replacement for any true ISO 15552 cylinder with a 50 mm bore, 1000 mm stroke, and PT port threads. Match your existing mounting hardware using LB foot brackets, FA/FB flanges, or TC trunnion styles. Note that standard air cushions only decelerate the piston at stroke ends; if the air supply is lost, the load will drop. Use the SAIL variant with an air-released lock or an external pilot check valve for fail-safe 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 SAI50AX1000 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes. The SAI50X1000 adheres strictly to ISO 15552 dimensional standards, meaning it is a direct replacement for any 50 mm bore profile cylinder with a 1000 mm stroke, provided your mounting interface and PT port sizes match.
