About the Airtac SAI40 Standard Air Cylinder SAI40X175
The AirTAC SAI40X175 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 175mm stroke. It generates 628N of push force and 528N of pull force at 0.5 MPa, making it a solid choice for medium-duty positioning tasks.
This extruded aluminum barrel omits traditional tie-rods and includes sensor grooves on both sides for straightforward switch placement. The standard configuration utilizes a carbon steel piston rod and NBR seals, though Viton (H) alternatives are available for high-temperature environments up to 70 C.

Where the Airtac SAI40 Standard Air Cylinder SAI40X175 Is Used
Package Diverting
Provides the 628N push force needed to actuate routing gates on 40mm belt conveyor lines without overshooting the 175mm travel.
Clamp Actuation
Ideal for driving mid-sized machining clamps where the 175mm stroke accommodates varying workpiece widths.
Pallet Stops
Deploys reliably as an automated pallet stop gate, utilizing its 30-800 mm/s speed range for rapid cycling.
Is the Airtac SAI40 Standard Air Cylinder SAI40X175 the Right Cylinder?
Select this 40mm bore when a 32mm bore (402N push at 0.5 MPa) lacks the necessary thrust, but a 50mm bore (982N push) would be physically oversized. At a 175mm stroke, the extended rod is moderately exposed; if your mechanism imposes lateral forces, use an external guide rail to prevent rod-bearing wear.
This model features a PT tapered port thread and a G1/4 air connection. It serves as a dimensionally interchangeable drop-in replacement per ISO 15552 mounting dimensions, compatible with FA or FB flange accessories. Note that a plain SAI does not hold position unpowered; for dead-load holding, specify the SAIL variant or use an external pilot 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 SAI40 Standard Air Cylinder SAI40X175 FAQ
At 0.5 MPa operating pressure, the SAI40X175 provides 628N of push force and 528N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 879N.
Yes, the SAI40X175 is built to ISO 15552 dimensional standards, making it a drop-in replacement for other ISO 15552 profile cylinders of the same bore and stroke. Mounting accessories like the TC trunnion are fully compatible.
