About the Airtac SAI100 Standard Air Cylinder SAI100BX425
The AirTAC SAI100X425 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 425mm stroke. It generates a substantial 3927 N of push force at 0.5 MPa, extending to 5497 N at 0.7 MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh environments. It utilizes a PT G1/2 port and lacks a magnet (-S not specified), meaning external position sensing must be handled mechanically rather than via reed switches.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX425 Is Used
Heavy Material Handling
Ideal for driving large pallet stops or heavy-load diverters on conveyor lines where high kinetic energy and 3927 N of thrust are required.
Automotive Assembly Press
Provides the robust linear motion needed to seat heavy automotive components, utilizing the 425mm stroke for deep press travel.
Pallet Lift Stations
Delivers reliable vertical lifting force for heavy pallet manipulation, relying on external guides to stabilize the long 425mm extension.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX425 the Right Cylinder?
When sizing this actuator, stepping down to an 80mm bore yields 2513 N of push force at 0.5 MPa, while moving up to a 125mm bore provides 6136 N. Because the 425mm stroke creates a long unsupported rod extension, applying lateral or side loads will induce severe bending stresses on the rod bearing. To prevent premature seal wear and binding, mount an external guide rail or select a fully guided cylinder for your payload.
This unit is dimensionally interchangeable per ISO 15552, serving as a direct drop-in replacement for other standard profile cylinders with matching 100mm bore, 425mm stroke, G1/2 port, and mounting accessory dimensions. Note that standard double-acting cylinders cannot hold a load if air pressure drops; if your application requires fail-safe position holding without live pressure, consider the SAIL variant with an air-released lock or an external rod lock.
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 SAI100BX425 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X425 is a genuine ISO 15552 profile cylinder, making its mounting interface and center-to-center dimensions fully interchangeable with other ISO 15552 cylinders of the same bore and stroke. You can drop it in as a replacement without modifying your machine plate.
