About the Airtac SAI50 Standard Cylinder SAI50BX475
The AirTAC SAI50X475 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force and 825 N of pull force at 0.5 MPa. Its 475 mm stroke makes it well-suited for mid-range linear actuation tasks requiring substantial travel distance. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting accessory installation.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and does not include a magnet. For applications requiring end-of-stroke deceleration, the adjustable air cushions at both ends protect machinery from impact loads.

Where the Airtac SAI50 Standard Cylinder SAI50BX475 Is Used
Long-Travel Diverting
Actuates routing gates on packaging lines where the 475 mm stroke shifts products between parallel conveyor lanes.
Pallet Push-Off
Provides the 982 N push force needed to index heavy cardboard cartons off an accumulation roller bed.
Material Extrusion
Drives medium-duty forming presses, utilizing adjustable cushions to smoothly decelerate the 50 mm bore at stroke end.
Is the Airtac SAI50 Standard Cylinder SAI50BX475 the Right Cylinder?
Select this 50 mm bore when a 40 mm bore (offering 628 N at 0.5 MPa) lacks the necessary thrust, but a 63 mm bore (providing 1559 N) would be physically oversized. The 475 mm stroke provides ample extension, but because it exceeds 300 mm, the unsupported piston rod is susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or utilize a dedicated guided cylinder.
As a true ISO 15552 profile cylinder, this unit serves as a direct replacement for any standard 50 mm bore cylinder with a 475 mm stroke, matching standard PT G1/4 ports and mounting footprints like FA flange or LB foot brackets. Note that standard SAI cylinders rely on continuous air pressure to hold position; if your application requires mechanical locking upon air loss, specify the SAIL variant or use an external pilot-operated check valve.
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 SAI50BX475 FAQ
At 0.5 MPa operating pressure, the SAI50X475 generates 982 N of push force and 825 N of pull force. If you increase pressure to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X475 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other 50 mm bore ISO 15552 profile cylinders with a 475 mm stroke, matching the G1/4 port size and standard mounting dimensions.
