About the Airtac SAI100 Standard Air Cylinder SAI100BX90
The AirTAC SAI100X90 is a double-acting ISO 15552 profile-barrel cylinder featuring a 100mm bore and a 90mm stroke. 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 medium-to-heavy actuation tasks.
This specific configuration features a SUS304 stainless steel rod (material code B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered thread ports and lacks a magnet, meaning it is optimized purely for mechanical drive rather than position sensing.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX90 Is Used
Press Ejection
Provides the 3927 N push force required to reliably eject finished metal parts from a hydraulic press bed.
Pallet Diversion
Actuates heavy-duty diverter arms on a packaging line to route loaded pallets onto secondary conveyors.
Clamp Actuation
Drives large mechanical clamping arms to secure bulky workpieces during automated welding operations.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX90 the Right Cylinder?
If your application requires less force, stepping down to the 80mm bore yields 2513 N of push force at 0.5 MPa. Because this 90mm stroke is relatively short, side-load bending is minimal, but you should still ensure rigid coupling to the load. If the machinery loses air pressure, this standard cylinder will not hold its load and the piston will drift; for position holding without live pressure, consider the SAIL variant or an external rod lock. To match this exact unit for a drop-in replacement, specify a 100mm bore, 90mm stroke, PT G1/2 port, and the desired mounting accessory like an FA flange.
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 SAI100BX90 FAQ
