About the Airtac SAI50 Standard Cylinder SAI50BX1000S
The AirTAC SAI50X1000-S is a double-acting ISO 15552 profile cylinder engineered for long-stroke actuation. It provides a theoretical push force of 982 N at 0.5 MPa, making it well-suited for moving moderate loads over an extended 1000 mm distance. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. It is factory-fitted with a magnet (-S) for seamless integration with CMSE or DMSE reed switches, which seat neatly into the dual sensor grooves machined on both sides of the barrel. Ports feature PT tapered threads for secure, leak-free pneumatic connections.

Where the Airtac SAI50 Standard Cylinder SAI50BX1000S Is Used
Long-Stroke Material Transfer
Pushes products or pallets across a 1000 mm gap on a packaging line, utilizing the 982 N force at 0.5 MPa to overcome friction on guide rails.
High-Reach Elevator Door
Actuates large vertical access doors on storage enclosures, relying on the SUS304 rod to resist moisture and the magnet for position confirmation.
Large Format Film Handling
Moves cutting heads or film carriages over a wide span, taking advantage of the smooth ISO 15552 profile barrel and adjustable end cushions.
Is the Airtac SAI50 Standard Cylinder SAI50BX1000S the Right Cylinder?
Selecting this 50 mm bore cylinder makes sense when your application requires the 982 N push force at 0.5 MPa but the 40 mm bore (628 N) falls short. If you need substantially more power, stepping up to the 63 mm bore yields 1559 N at the same pressure. Because this model features a 1000 mm stroke, the extended rod is highly susceptible to bending under side loads; always utilize an external guide rail or a dedicated guided cylinder to support the payload and prevent premature rod-bearing wear.
As a dimensionally interchangeable ISO 15552 unit, this cylinder serves as a direct replacement for other standard profile cylinders with matching 50 mm bore, 1000 mm stroke, PT ports, and standard mounting accessories like FA flanges or TC trunnions. Note that the adjustable air cushions only decelerate the piston at stroke ends; they will not hold a load if air pressure is lost. For dead-load holding, specify the SAIL or BSAI locking variant.
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 SAI50BX1000S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
No, the extended 1000 mm rod is vulnerable to bending under lateral loads. You must use an external linear guide or a guided cylinder to support the load and prevent damage to the rod bearing.
