About the Airtac SAI40 Standard Air Cylinder SAI40BX195S
The AirTAC SAI40X195-S is a double-acting ISO 15552 profile cylinder engineered for standardized mounting. Delivering 879N of push force at 0.7 MPa, this 40mm bore unit utilizes a 195mm stroke to bridge the gap between compact and mid-range automation tasks. Its extruded aluminum barrel omits tie-rods, providing a clean exterior that drops directly into existing ISO 15552 footprints.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. It is equipped with a piston magnet (-S) to trigger CMSE or DMSE reed switches housed in the dual sensor grooves along the barrel. Fluid ports feature PT tapered threads, ensuring robust, mechanically sealed pneumatic connections.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX195S Is Used
Stainless Rod Clamping
Ideal for securing machined components during secondary operations, utilizing the SUS304 rod to resist corrosion from cutting fluids.
Package Diverting
Provides the necessary 628N push force at 0.5 MPa to reliably index cardboard cartons on a packaging line without damaging the goods.
Gate Actuation
The 195mm stroke smoothly opens and closes access gates on automated machinery, with the -S magnet confirming gate position via DMSE sensors.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX195S the Right Cylinder?
Select this 40mm bore when an application demands more power than a 32mm variant (which provides 563N at 0.7 MPa) but lacks the physical space for a 50mm cylinder (1374N at 0.7 MPa). The 195mm stroke offers ample extension for indexing and clamping operations. Because the stroke exceeds 300mm? No, at 195mm side-load risks are minimal, but always ensure linear guidance for heavy payloads.
As a standard double-acting actuator, this cylinder relies on continuous air pressure to maintain its position. If pneumatic supply is lost, the rod will drift. For applications requiring strict position holding during exhaust or emergency stop, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. To match this unit for replacement, verify the 40mm bore, 195mm stroke, G1/4 PT port, and required mounting accessory like an FA flange or LB foot.
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 SAI40BX195S FAQ
At an operating pressure of 0.7 MPa, this 40mm bore cylinder generates 879N of push force and 724N of pull force. At 0.5 MPa, the push force is 628N.
Yes, the SAI series is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders of the same bore and stroke, provided you match the G1/4 port and mounting interface.
