About the Airtac SAI40 Standard Air Cylinder SAI40BX105S
The AirTAC SAI40X105-S is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force and 528 N of pull force at 0.5 MPa. Its 105 mm stroke provides a balanced mid-range extension for compact machinery. Because it adheres strictly to ISO 15552 dimensional standards, it serves as a direct replacement for other cylinders sharing this mounting interface.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance in wet or washdown environments. It includes a magnetic piston (-S) for use with CMSE and DMSE sensor switches, which mount directly into the dual sensor grooves on the extruded aluminum barrel. Ports utilize a PT tapered thread, and the standard TPU seals accommodate operating temperatures from -20 to +70 C.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX105S Is Used
Packaging Equipment
Drives short-stroke sealing and flap-folding arms where the SUS304 rod resists occasional washdowns and the 628 N force secures heavy cardboard.
Material Diverters
Actuates routing gates on 40 mm bore assemblies, using the magnetic piston to confirm gate position before product transfer.
Small Press Fixtures
Provides reliable clamping force for light-duty assembly presses, benefiting from the adjustable cushions to prevent end-of-stroke impact.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX105S the Right Cylinder?
Select this 40 mm bore when an application requires stepping up from the 32 mm class (which provides 402 N push at 0.5 MPa) to handle heavier actuation without the bulk of a 50 mm cylinder. The 105 mm stroke is ideal for short, precise movements. For applications requiring position holding without continuous air pressure, note that the standard adjustable air cushions only decelerate the piston at stroke ends; you must specify an external pilot-operated check valve or use a SAIL lock variant for true load holding.
When replacing an existing ISO 15552 cylinder, match the 40 mm bore, 105 mm stroke, G1/4 port size, and your required mounting accessory (such as LB foot or FA flange). The integrated magnet allows for precise end-of-stroke detection using standard AirTac sensors.
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 SAI40 Standard Air Cylinder SAI40BX105S FAQ
At 0.5 MPa operating pressure, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X105-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the 40 mm bore and 105 mm stroke, provided you match the G1/4 port and mounting accessories.
