About the Airtac SAI40 Standard Air Cylinder SAI40BX130S
The AirTAC SAI40X130-S is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa, extending to 879 N at 0.7 MPa. Its 130 mm stroke is optimal for mid-length positioning tasks, while the extruded aluminum barrel eliminates tie-rods for a clean, modern exterior.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet (-S) enabling seamless integration with CMSE or DMSE sensor switches along the dual grooves. It also features PT tapered port threads, ensuring a robust, sealed pneumatic connection in demanding environments.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX130S Is Used
Component Clamping
Provides reliable 628 N clamping force at 0.5 MPa for securing mid-sized metal or plastic components during machining and assembly processes.
Package Diverting
The 130 mm stroke offers precise actuation for routing packages or diverting product flow on automated material handling lines.
Shuttle Gating
Utilizes the SUS304 rod and integrated magnet to reliably operate storage shuttle gates and automated inventory doors in varied climates.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX130S the Right Cylinder?
Selecting this 40 mm bore over the smaller 32 mm variant upgrades your thrust from 402 N to 628 N at 0.5 MPa, providing the extra power needed for moderately heavy payloads. At 130 mm stroke, the piston travels sufficiently within standard limits, though maintaining proper rod-bearing alignment is always recommended to prevent uneven wear.
As a dimensionally interchangeable ISO 15552 profile cylinder, this model serves as a direct replacement for other standard 40 mm bore actuators. To finalize your setup, pair it with a PT port manifold, FA/FB flange or LB foot mounting accessories, and CMSE/DMSE sensors. If your mechanism loses air pressure and must hold a load vertically without drifting, the standard air cushion will not lock the piston; you must specify the SAIL or BSAI clamp-lock variant instead.
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 SAI40BX130S FAQ
At a standard 0.5 MPa operating pressure, this 40 mm bore cylinder produces 628 N of push force and 528 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 879 N.
Yes, the SAI40X130-S is a genuine ISO 15552 profile cylinder, meaning its mounting interface and physical envelope dimensions are fully interchangeable with other ISO 15552 standard cylinders of the same bore size.
