About the Airtac SAI40 Standard Air Cylinder SAI40X130
The AirTAC SAI40X130 is a double-acting ISO 15552 profile cylinder engineered to deliver 879N of push force at 0.7 MPa. Its 130mm stroke provides the exact mid-range travel needed for compact assembly automation. The extruded aluminum barrel eliminates protruding tie rods, resulting in a clean exterior that fits seamlessly into tight machine envelopes.
This configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because it lacks an integrated magnet, it relies on external physical cues rather than internal position sensing. For environments experiencing elevated thermal loads, the standard TPU seals can be swapped for Viton high-temperature variants.

Where the Airtac SAI40 Standard Air Cylinder SAI40X130 Is Used
Component Clamping
Provides reliable 879N clamping force at 0.7 MPa for securing mid-sized aluminum housings during CNC machining operations.
Package Diverting
Utilizes its 130mm stroke to push moderate-weight cartons off a main conveyor belt into secondary packaging lanes.
Press Fit Operations
Drives small bushings or bearings into machined blocks with precise 40mm bore actuation and adjustable end cushions.
Is the Airtac SAI40 Standard Air Cylinder SAI40X130 the Right Cylinder?
Select this 40mm bore when an application requires stepping up from the 32mm class, which only yields 563N at 0.7 MPa, but does not demand the larger 1374N output of a 50mm unit. The 130mm stroke is well below the 300mm threshold, so rod-bearing bending is not a primary concern here. However, if your mechanism must hold a vertical load without continuous air pressure, note that standard SAI cylinders will drift; you should specify the SAIL variant with an air-released lock instead.
As a true ISO 15552 cylinder, it offers a dimensionally interchangeable mounting interface. You can directly replace competing ISO 15552 profile cylinders by matching the 40mm bore, 130mm stroke, G1/4 port, and your preferred 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 SAI40X130 FAQ
At a standard operating pressure of 0.7 MPa, this 40mm bore cylinder generates 879N of push force and 528N of pull force. At 0.5 MPa, the push force is 628N.
Yes, the SAI40X130 is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 profile cylinders by matching the 40mm bore, 130mm stroke, and G1/4 port size.
