About the Airtac SAI40 Standard Air Cylinder SAI40X210
The AirTAC SAI40X210 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 210mm stroke. It generates 879N of push force at 0.7MPa, making it well-suited for moderate-duty handling tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This unit utilizes a standard carbon steel piston rod and PT tapered port threads. For environments requiring heat resistance, the seal configuration can be upgraded from standard TPU to Viton (H). Because this specific SKU lacks the -S magnet suffix, it does not support reed or solid-state sensor switches along the dual barrel grooves.

Where the Airtac SAI40 Standard Air Cylinder SAI40X210 Is Used
Package Diverting
Provides the 628N push force at 0.5MPa needed to actuate medium-sized diverter arms on packaging lines.
Clamp Actuation
Extends 210mm to position and hold workpieces securely during light machining or assembly processes.
Pallet Stops
Functions as a reliable pneumatic stop gate for pallets accumulating on roller conveyors.
Is the Airtac SAI40 Standard Air Cylinder SAI40X210 the Right Cylinder?
Selecting this 40mm bore over the smaller 32mm variant increases your 0.5MPa push thrust from 402N to 628N, a significant uplift for heavier tooling. Conversely, if your payload demands even greater force, stepping up to the 50mm bore yields 982N at the same pressure. The 210mm stroke falls under standard made-to-order dimensions, so no custom long-stroke pricing applies.
With a 210mm extension, the unsupported rod length is moderate, but side-load management remains important to prevent premature rod-bearing wear. Utilizing external guide rails or a guided cylinder carriage is recommended if the load is not perfectly axial. Note that the adjustable air cushions only decelerate the piston at stroke ends; they do not lock the rod. If pneumatic pressure is lost, the load will drift, requiring an external pilot check valve or the SAIL locking variant for secure holding.
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 SAI40X210 FAQ
At an operating pressure of 0.7MPa, the push force is 879N and the pull force is 528N. If pressure is increased to 0.9MPa, the push force reaches 1130N.
Yes, the SAI40X210 is dimensionally interchangeable per ISO 15552. You can drop it into existing mountings using standard FA flanges or LB foot brackets, provided the 40mm bore, 210mm stroke, and G1/4 port match your interface.
