About the Airtac SAI40 Standard Air Cylinder SAI40X230
The AirTAC SAI40X230 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa. Its 230 mm stroke makes it well-suited for mid-range linear actuation tasks. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops into standard ISO 15552 mounting footprints.
This configuration features a standard carbon steel piston rod and PT tapered port threads. Because it lacks a built-in magnet, position sensing requires external limit switches. For higher temperature environments, the standard TPU seals can be swapped for Viton (H) or NBR (N) alternatives.

Where the Airtac SAI40 Standard Air Cylinder SAI40X230 Is Used
Package Diverting
Provides the 628 N push force needed to deflect medium-weight cartons on a sorting line.
Clamp Actuation
Extends 230 mm to position workholding clamps around larger machined parts.
Pallet Stop Gate
Raises and lowers a physical stop gate to control pallet flow on an assembly conveyor.
Is the Airtac SAI40 Standard Air Cylinder SAI40X230 the Right Cylinder?
Selecting this 40 mm bore over a 32 mm variant upgrades your thrust from 402 N to 628 N at 0.5 MPa, while stepping up to a 50 mm bore yields 982 N. At 230 mm of stroke, the unsupported rod length increases the risk of bending under side loads. To prevent rod-bearing wear, implement an external guide rail or choose a guided cylinder for heavy off-center loads.
If your mechanism must hold a load vertically when air pressure is removed, note that the standard adjustable air cushions only decelerate the piston at stroke end. They do not brake or lock the rod. For secure position holding without live pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. Replacement matching requires a 40 mm bore, 230 mm stroke, G1/4 port, and your desired 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 SAI40X230 FAQ
At 0.5 MPa operating pressure, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X230 is dimensionally interchangeable per ISO 15552. You can drop it into existing mounting interfaces designed for other ISO 15552 profile cylinders, provided the 40 mm bore, 230 mm stroke, and G1/4 port match your footprint.
