About the Airtac SAI80 Standard Air Cylinder SAI80BX500
The AirTAC SAI80X500 is a double-acting ISO 15552 profile cylinder engineered to deliver 2513 N of push force and 2268 N of pull force at 0.5 MPa. Its 500 mm stroke is ideal for mid-range linear positioning tasks requiring substantial travel. Operating at speeds of 30-800 mm/s, this pneumatic actuator integrates adjustable air cushions at both ends to smoothly decelerate the piston.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and does not include a magnet, meaning it is optimized for purely mechanical operation without external position sensing. As a genuine AirTAC component, it ensures reliable, long-life automation performance.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX500 Is Used
Pallet Transfer
Ideal for driving 500 mm stroke pallet lifts or pushers on heavy-duty conveyor lines, utilizing its 2513 N force to shift loaded pallets smoothly.
Machine Tool Clamping
Provides robust clamping force for large machining centers, where the SUS304 rod offers reliable performance against coolant splashes and moisture.
Material Handling
Suitable for actuating large packaging or sorting gates that require a long 500 mm travel distance to redirect bulky products.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX500 the Right Cylinder?
Selecting this 80 mm bore over the smaller 63 mm bore (which provides 1559 N push at 0.5 MPa) is necessary when your application force exceeds 1500 N but does not warrant the larger 100 mm bore (3927 N). The 500 mm stroke provides extensive reach, but strokes of this length require careful attention to side-load management. An unsupported rod of this length is prone to bending under lateral stress; utilizing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This model is dimensionally interchangeable per ISO 15552, making it a direct replacement for other standard profile cylinders with an 80 mm bore, 500 mm stroke, G3/8 port, and compatible mounting accessories like FA flanges or TC trunnions. Note that because it lacks a magnet, position sensing is not possible without modification; if you require sensors, select the -S option. Additionally, the adjustable air cushions only decelerate the piston at stroke ends and do not hold the load if air pressure is lost.
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 SAI80BX500 FAQ
At an operating pressure of 0.5 MPa, the SAI80X500 cylinder provides a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
Yes, the SAI80X500 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, without claiming to be identical to any specific brand.
