About the Airtac SAI100 Standard Air Cylinder SAI100BX210
The AirTAC SAI100X210 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 210mm stroke. Because 210mm falls outside the standard stroke increments, this is a made-to-order nonstandard stroke configuration. It delivers a robust 3927 N of push force and 3681 N of pull force at a 0.5 MPa operating pressure, making it well-suited for heavy-duty actuation tasks.
This specific unit is configured with a SUS304 stainless steel rod (material code B) for superior corrosion resistance in demanding environments. It utilizes PT tapered port threads, and because a magnet is not specified, it does not include the internal magnetic piston for proximity sensing. The extruded aluminum barrel features dual sensor grooves, allowing for easy integration of CMSE or DMSE switches if a magnetic piston is added later.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX210 Is Used
Heavy-Duty Stamping
Provides the 3927 N push force at 0.5 MPa needed to actuate medium-tonnage stamping and forming presses reliably.
Pallet Diversion
Utilizes the 210mm stroke to push heavy pallets off high-throughput conveyor lines, with the SUS304 rod resisting humid plant environments.
Automated Assembly Press
Delivers consistent downward pressure for pressing bearings or pins into housings on automated assembly lines.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX210 the Right Cylinder?
With a 100mm bore, this cylinder generates substantial thrust. If your application requires less force, stepping down to a 63mm bore yields 1559 N of push force at 0.5 MPa, which may suffice for lighter loads. Conversely, moving up to a 125mm bore provides 6136 N for highly demanding press operations. Since the 210mm stroke exceeds 300mm? No, but even at 210mm, if you experience side loading, consider using an external guide rail to prevent rod-bearing wear.
The SAI100X210 is dimensionally interchangeable with other ISO 15552 cylinders, serving as a drop-in replacement when matching the 100mm bore, 210mm stroke, G1/2 port, and appropriate mounting accessories like FA flanges or TC trunnions. Note that this standard cylinder relies on adjustable air cushions to decelerate the piston at stroke ends; it does not hold loads pneumatically. If your machinery requires dead-stop positioning without live air pressure, integrate an external pilot-operated check valve or specify the SAIL locking variant.
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 SAI100BX210 FAQ
At a 0.5 MPa operating pressure, the SAI100X210 generates a push force of 3927 N and a pull force of 3681 N. At the maximum 1.0 MPa pressure, it can reach a theoretical maximum force of 801 kgf.
Yes, the SAI is a true ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders matching the 100mm bore, 210mm stroke, and G1/2 port size, making it a drop-in replacement for standard mounting interfaces.
