About the Airtac SAI50 Standard Cylinder SAI50BX500
The AirTAC SAI50X500 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. With a 500 mm stroke, it provides the extended travel necessary for automated material handling and large-format packaging equipment. The extruded aluminum barrel design omits traditional tie rods, offering a clean, standardized mounting interface that drops in seamlessly with other ISO 15552 compliant actuators.
This specific configuration is built with a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in humid or washdown environments. It utilizes tapered PT port threads and lacks a standard magnet; if position sensing is required later, a separate -S variant would be necessary to accommodate CMSE or DMSE sensors in the dual-side barrel grooves.

Where the Airtac SAI50 Standard Cylinder SAI50BX500 Is Used
Material Transfer
Drives long-travel package pushers across wide conveyor belts, utilizing the full 500 mm stroke to clear palletizing lanes efficiently.
Pallet Dispensers
Indexes empty pallets into loading zones, relying on the 982 N push force at 0.5 MPa to overcome friction and move heavy wooden bases.
Door Automation
Actuates large industrial partition doors where the SUS304 rod material provides necessary resilience against ambient humidity and temperature fluctuations.
Is the Airtac SAI50 Standard Cylinder SAI50BX500 the Right Cylinder?
Selecting this 50 mm bore over the smaller 40 mm bore yields a significant force jump from 628 N to 982 N at 0.5 MPa, while stepping up to the 63 mm bore provides 1559 N for heavier payloads. At 500 mm of travel, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, pair this actuator with external linear guides or a fully guided cylinder assembly.
This model's PT porting matches standard pneumatic plumbing, and its ISO 15552 dimensions allow direct mounting using FA/FB flanges or TC trunnion brackets. Note that the standard SAI does not hold its position if air pressure is lost; for suspended loads requiring fail-safe drop protection, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead.
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 SAI50BX500 FAQ
At an operating pressure of 0.5 MPa, 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 SAI50X500 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 cylinders of the same bore and stroke, allowing for a direct replacement.
