About the Airtac SAI80 Standard Air Cylinder SAI80BX475
The AirTAC SAI80X475 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 2513 N of push force at 0.5 MPa. With a 475 mm stroke, it provides the extended travel needed for large packaging machines and heavy material handling. The extruded aluminum barrel design integrates sensor grooves on both sides for straightforward position feedback installation.
This specific configuration is built with a SUS304 stainless steel piston rod (material code B), offering superior corrosion resistance for humid or washdown environments. It utilizes PT tapered port threads and operates without a magnet. As a genuine AirTAC component, it ensures reliable pneumatic performance across its 30-800 mm/s speed range.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX475 Is Used
Pallet Handling
Provides the long 475 mm travel and 2513 N force required to push heavy pallets smoothly onto transfer lines.
Automated Warehousing
Ideal for actuating large sorting gates and lifting mechanisms where the SUS304 rod withstands varied environmental conditions.
Heavy Assembly Presses
Delivers consistent downward clamping pressure for securing heavy components during automated assembly processes.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX475 the Right Cylinder?
Selecting this 80 mm bore cylinder makes sense when a 50 mm bore (providing 982 N at 0.5 MPa) lacks the thrust for your payload, but a 100 mm bore (3927 N) would be excessive. The 475 mm stroke requires careful attention to mechanical stability; long unsupported rods are prone to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or use a guided cylinder assembly.
This model functions as a direct replacement for other ISO 15552 profile cylinders, matching standard mounting dimensions for foot (LB), flange (FA), and trunnion (TC) accessories. It features a G3/8 port. Note that standard SAI cylinders rely on adjustable air cushions to decelerate the piston at stroke ends, but they cannot hold a load if air pressure is lost. For dead-load holding, consider the SAIL or BSAI locking variants.
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 SAI80 Standard Air Cylinder SAI80BX475 FAQ
At 0.5 MPa operating pressure, the SAI80X475 generates 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
No. The standard SAI cylinder uses adjustable air cushions only to decelerate the piston at end-of-stroke; it does not lock or hold position if air pressure drops. For fail-safe load holding, use the SAIL (air-released lock) or BSAI (clamp-lock) variants.
