About the Airtac SAI100 Standard Air Cylinder SAI100BX250
The AirTAC SAI100X250 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for moving substantial loads over its 250 mm stroke. The extruded aluminum barrel design omits tie-rods, ensuring a clean exterior that resists debris accumulation.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. Fluid ports utilize a PT tapered thread type. Because a magnet is not specified, this unit does not include internal magnetic rings for direct sensor detection.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX250 Is Used
Heavy Stamping Press
Provides the high 3927 N push force required to actuate heavy stamping dies and form metal components securely.
Pallet Diverting
Shifts heavy product pallets across conveyor lines, utilizing the 250 mm stroke to clear adjacent routing lanes effectively.
Large Clamp Fixtures
Secures oversized workpieces in machining cells, where the robust 100 mm bore ensures rigid clamping under cutting forces.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX250 the Right Cylinder?
Select this 100 mm bore when an 80 mm cylinder (providing 2513 N push at 0.5 MPa) lacks the thrust for your heavier fixtures, but you want to avoid the larger footprint of a 125 mm variant. The 250 mm stroke is standard and falls well within the 1500 mm maximum limit for this bore.
With a 250 mm stroke, the unsupported rod length is moderate, but operators should still verify that side loads are minimized or supported by external linear guides to prevent premature rod-bearing wear. If your machinery loses air pressure, this standard cylinder cannot hold its load vertically and will drift; for fail-safe holding, specify the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder. Being dimensionally interchangeable per ISO 15552, it serves as a drop-in replacement for other ISO 15552 profile cylinders, matching the G1/2 port and standard mounting accessories like FA flanges or TC trunnions.
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 SAI100BX250 FAQ
At 0.5 MPa operating pressure, this double-acting cylinder generates a push force of 3927 N and a pull force of 3681 N. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes. The SAI100X250 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions, G1/2 port size, and accessory interfaces are fully interchangeable with other standard ISO 15552 cylinders.
