About the Airtac SAI40 Standard Air Cylinder SAI40X95
The AirTAC SAI40X95 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa. Its 95 mm stroke is well-suited for short-travel clamping and indexing tasks. The extruded aluminum barrel eliminates tie-rods, providing a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This configuration features a standard carbon steel piston rod and PT tapered port threads. For environments requiring position feedback, the barrel includes dual sensor grooves compatible with CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI40 Standard Air Cylinder SAI40X95 Is Used
Short-Stroke Clamping
Provides reliable 628 N clamping force at 0.5 MPa for securing workpieces during light machining or assembly operations.
Package Diverting
Actuates diverting arms or gating mechanisms on packaging lines where a compact 95 mm stroke rapidly redirects product flow.
Material Ejection
Pushes completed parts out of molding or pressing stations with precise, repeatable force in confined spaces.
Is the Airtac SAI40 Standard Air Cylinder SAI40X95 the Right Cylinder?
Select this 40 mm bore when an application requires stepping up from the 32 mm class (which provides 402 N at 0.5 MPa) to handle heavier payloads without the bulk of a 50 mm body. The 95 mm stroke keeps the retracted length compact, making it ideal for tight machinery envelopes.
Because this is a standard double-acting cylinder, it relies on continuous air pressure to maintain rod position; if air is exhausted, the piston will drift. For applications needing fail-safe load holding, consider the SAIL variant with an air-released lock. Replacement is straightforward: match the 40 mm bore, 95 mm stroke, G1/4 port, and mounting accessories like FA flanges or LB foot brackets.
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 SAI40X95 FAQ
At 0.7 MPa operating pressure, this 40 mm bore cylinder generates 879 N of push force and 724 N of pull force. It can reach a theoretical maximum of 1130 N at 1.0 MPa.
Yes, the SAI40X95 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 40 mm bore, 95 mm stroke, and G1/4 port.
