About the Airtac SAI100 Standard Air Cylinder SAI100BX45
The AirTAC SAI100X45 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100 mm bore actuator is built to handle substantial loads. The 45 mm stroke provides rapid, short-travel actuation for clamping or pressing tasks. A standout feature of this specific configuration is the SUS304 stainless steel piston rod (material code B), which provides superior corrosion resistance compared to standard carbon steel, making it ideal for humid or chemically active environments.
This model uses PT tapered port threads for a mechanically sealed pneumatic connection. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches if a magnet is added later. As a genuine AirTAC component, it guarantees dimensional interchangeability with other ISO 15552 cylinders, ensuring a seamless, drop-in replacement for your existing standard mounting setups.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX45 Is Used
Heavy-Duty Stamping
Provides the necessary 3927 N of force at 0.5 MPa to execute short 45 mm stamping and forming operations on metal or composite parts.
Pallet Arresting
Acts as a robust stop gate for heavy pallets on a conveyor line, using its SUS304 rod to withstand environmental moisture and repeated impact.
Industrial Clamping
Secures large workpieces during machining or welding, utilizing the 100 mm bore's high thrust capacity to lock heavy components rigidly in place.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX45 the Right Cylinder?
Selecting this 100 mm bore actuator makes sense when your application requires upward of 3927 N of thrust at 0.5 MPa. If your load requirements drop closer to 2513 N, stepping down to the 80 mm bore neighbor is more efficient. Conversely, if you need to exceed 5497 N, consider the 125 mm variant. Because the stroke is a short 45 mm, rod-bearing bending and side-load stress are minimal, meaning external guides are not strictly necessary for structural integrity here.
For applications that require the load to be held securely in place without constant live air pressure, remember that a standard SAI cylinder will drift or drop when pressure is lost. The adjustable air cushions at both ends only decelerate the piston near stroke end; they do not act as a brake. To maintain position during exhaust or valve centering, you must integrate an external pilot-operated check valve or specify the SAIL (air-released lock) 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 SAI100BX45 FAQ
