About the Airtac SAI100 Standard Air Cylinder SAI100BX290
The AirTAC SAI100X290 is a double-acting ISO 15552 profile cylinder offering a robust 3927 N push force at 0.5 MPa and 5497 N at 0.7 MPa. Its extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies cleaning and reduces dirt accumulation in demanding environments.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance, paired with PT tapered port threads. Because a magnet is not specified, it ships without sensor tracks; if position feedback is needed, specify the -S option to enable dual-side sensor grooves compatible with CMSE and DMSE switches.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX290 Is Used
Heavy Pressing Operations
Ideal for pressing bearings or pins, utilizing its 5497 N push force at 0.7 MPa to seat components firmly in automated assembly lines.
Large Package Diverting
The 290 mm stroke provides the reach needed to divert heavy pallets or oversized totes across wide conveyor belts in logistics hubs.
Clamping Heavy Weldments
Holds large steel frames securely in place during robotic welding, with the SUS304 rod resisting weld spatter and heat.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX290 the Right Cylinder?
At 0.5 MPa, this 100 mm bore generates 3927 N of push force. If your application requires less force, stepping down to the 80 mm bore yields 2513 N, while moving up to the 125 mm bore provides 6136 N. The 290 mm stroke is well within the 1500 mm maximum standard stroke for this bore, making it a readily available made-to-order option.
With a 290 mm stroke, the unsupported rod length is significant; side loads can cause rod-bearing bending and premature wear. Use an external guide rail or a guided cylinder to prevent binding. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end—they do not hold a load. If pressure drops, the rod will drift; use an SAIL variant or an external rod lock for position holding.
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.
