About the Airtac SAI40 Standard Air Cylinder SAI40X200
The AirTAC SAI40X200 is a double-acting ISO 15552 profile cylinder built with an extruded aluminum barrel and a 200 mm stroke. It generates 628 N of push force at 0.5 MPa, making it well-suited for mid-range industrial actuation tasks.
This configuration features a standard carbon steel piston rod and PT tapered port threads. Because it lacks a magnet, external position sensing is not supported on this specific unit. The barrel incorporates dual sensor grooves, allowing you to easily switch to an -S variant if you later require CMSE or DMSE switches.

Where the Airtac SAI40 Standard Air Cylinder SAI40X200 Is Used
Package Diverting
Provides the 628 N push force needed to actuate diverter arms on medium-speed packaging conveyors.
Clamp Fixtures
Secures workpieces during secondary machining operations where a 200 mm extension positions the clamp safely away from the cutting zone.
Material Handling
Pushes standardized totes or pallets along roller lanes, utilizing the adjustable air cushions to soften end-of-stroke impacts.
Is the Airtac SAI40 Standard Air Cylinder SAI40X200 the Right Cylinder?
Choose this 40 mm bore when a 32 mm cylinder lacks sufficient thrust (402 N at 0.5 MPa) but a 50 mm unit is excessive. With a 200 mm stroke, the rod bearing experiences moderate side loads; using external guide rails or a guided cylinder helps prevent rod bending and premature seal wear.
This model is dimensionally interchangeable per ISO 15552, acting as a drop-in replacement for other standard profile cylinders. To match this exact configuration, select a 40 mm bore, 200 mm stroke, PT port thread, and your required mounting accessory like an LB foot or FA flange. Note that this standard cylinder will drift if air pressure is lost; use the SAIL variant if your application requires a pneumatic lock to hold a load safely.
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 SAI40X200 FAQ
At an operating pressure of 0.5 MPa, this 40 mm bore cylinder provides a push force of 628 N and a pull force of 528 N. It can reach up to 1130 N at 0.9 MPa.
Yes. The SAI40X200 adheres to ISO 15552 mounting dimensions, making it a drop-in replacement for other ISO 15552 profile cylinders. Ensure you match the 40 mm bore, 200 mm stroke, and PT ports.
