About the Airtac SAI40 Standard Air Cylinder SAI40BX200
The AirTAC SAI40X200 is a double-acting ISO 15552 profile cylinder engineered to deliver 628N of push force and 528N of pull force at 0.5 MPa. Its 200mm stroke makes it highly suitable for mid-range linear actuation tasks. The extruded aluminum barrel design omits traditional tie rods, providing a clean exterior that resists contamination.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and lacks a standard magnet, meaning it is optimized for pure mechanical force delivery without sensor integration.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX200 Is Used
Package Diverting
Provides the precise 628N force needed to actuate routing gates and pusher arms on medium-duty packaging conveyors.
Component Clamping
Ideal for securing workpieces during machining operations, utilizing its 200mm stroke to accommodate varying part sizes.
Material Handling
Drives vertical lifting arms in automated assembly lines where the corrosion-resistant SUS304 rod prevents environmental degradation.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX200 the Right Cylinder?
Selecting this 40mm bore over the smaller 32mm variant upgrades your thrust from 402N to 628N at 0.5 MPa, while stepping up to the 50mm bore yields 982N. Because this model features a 200mm stroke, it is crucial to manage side loads; long unsupported rods are susceptible to bending and premature bearing wear. Employing an external guide rail or a twin-rail guided cylinder will preserve the rod bearing and ensure smooth operation.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other ISO 15552 profile cylinders, matching standard 40mm bore, 200mm stroke, PT G1/4 ports, and standard mounting accessories (like FA flange or LB foot). Note that this standard cylinder relies on adjustable air cushions at both ends for end-of-stroke deceleration; it does not hold position pneumatically. If your application requires load holding upon air loss, consider the SAIL locking variant or an external rod lock.
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 SAI40BX200 FAQ
At a standard operating pressure of 0.5 MPa, the SAI40X200 generates a push force of 628N and a pull force of 528N. At 0.7 MPa, the push force increases to 879N.
Yes, the SAI40X200 is a genuine ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 standard cylinders. It matches the 40mm bore, 200mm stroke, and G1/4 port specifications.
