About the Airtac SAI50 Standard Cylinder SAI50BX900
The AirTAC SAI50X900 is a double-acting ISO 15552 profile cylinder engineered for long-trroke automation. Delivering a push force of 982 N at 0.5 MPa, this 50 mm bore unit utilizes a 900 mm stroke to bridge substantial operational gaps. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration incorporates a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. It features PT tapered port threads and lacks a standard magnet. For applications requiring end-of-stroke locking without continuous air pressure, the SAIL variant offers a pneumatic holding mechanism.

Where the Airtac SAI50 Standard Cylinder SAI50BX900 Is Used
Long-Stroke Material Push
Transfers products across wide conveyor gaps or diverters using the full 900 mm extension and 982 N of thrust at 0.5 MPa.
Pallet Positioning
Stages large pallets or totes at machining centers, leveraging the SUS304 rod to resist moisture in damp factory environments.
Automated Door Actuation
Opens and closes heavy machine guarding or industrial oven doors where a long reach and consistent double-acting force are required.
Is the Airtac SAI50 Standard Cylinder SAI50BX900 the Right Cylinder?
Selecting this 900 mm stroke model requires careful attention to side-load management. At this extended length, the unsupported piston rod is susceptible to bending under lateral forces; utilizing an external guide rail or a dedicated guided cylinder system will prevent premature rod-bearing wear. If your application demands less travel, the 40 mm bore provides 628 N at 0.5 MPa, while the 63 mm bore offers 1559 N for heavier loads.
As a dimensionally interchangeable ISO 15552 cylinder, this unit serves as a direct replacement for other standard profile cylinders sharing the same 50 mm bore, 900 mm stroke, G1/4 port, and mounting accessories like FA flanges or TC trunnions. Note that standard air cushions only decelerate the piston at stroke ends and will not maintain load position upon loss of air pressure.
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 SAI50BX900 FAQ
At an operating pressure of 0.5 MPa, 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 standard SAI model does not hold position without live air pressure. For vertical loads requiring fail-safe holding, consider the SAIL variant with an air-released lock or use an external pilot-operated check valve.
