About the Airtac SAI100 Standard Air Cylinder SAI100BX210S
The AirTAC SAI100X210-S is a double-acting profile cylinder built to the ISO 15552 standard. Providing a robust push force of 3927 N at 0.5 MPa, it handles heavy-duty positioning with ease. The 210 mm stroke is a made-to-order length, offering exact travel for specialized tooling.
This variant includes a magnetic piston for proximity sensing via CMSE or DMSE switches mounted in the dual side grooves. The piston rod is constructed from SUS304 stainless steel, delivering superior corrosion resistance for harsh production washdowns. Seals are standard TPU, with Viton options available for elevated thermal environments.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX210S Is Used
Heavy Stamping Press
Generates the 3927 N push force required to seat large bearings and heavy housings in automotive sub-assembly lines.
Pallet Diversion
Uses the 210 mm stroke to push loaded pallets off a main conveyor track into a secondary packaging cell.
Plastic Molding Eject
Drives large molded plastic panels out of press dies, utilizing the SUS304 rod to resist cooling fluid splashes.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX210S the Right Cylinder?
Selecting this bore is ideal when 80mm (2513 N at 0.5 MPa) lacks the thrust for moving heavy jigs, but a 125mm unit would be physically oversized. Because the 210 mm stroke is non-standard, expect a brief made-to-order lead time. The PT tapered port threads ensure a tight, mechanical seal during high-flow air exchange.
At 210 mm of travel, side loads can accelerate rod-bearing wear. Employ an external guide rail to prevent the piston rod from bending under off-center loads. If the machinery loses air pressure, this cylinder cannot hold its load; integrate an external rod lock or specify a SAIL variant for fail-safe position 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 SAI100 Standard Air Cylinder SAI100BX210S FAQ
At a 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes. The SAI100X210-S shares the exact ISO 15552 mounting interface and dimensions, making it a drop-in replacement for other standard profile cylinders of the same bore size.
