About the Airtac SAI100 Standard Air Cylinder SAI100BX500
The AirTAC SAI100X500 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty handling. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for moving substantial payloads across a 500 mm stroke. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies sensor placement.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. The barrel includes integrated sensor grooves on both sides for direct mounting of CMSE or DMSE switches. For applications requiring position holding without air pressure, consider the SAIL locking variant.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX500 Is Used
Automotive Body Welding
Provides the high clamping force needed to hold heavy steel panels in place during robotic welding operations.
Pallet Transfer Stops
Acts as a robust stop gate in high-mass pallet conveyors, absorbing the impact of moving loads.
Heavy Press Ejection
Exerts reliable push force to eject dense finished parts from hydraulic press beds.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX500 the Right Cylinder?
With a 500 mm stroke, the unsupported piston rod is susceptible to bending under side loads. To prevent premature wear of the rod bearing and seal damage, use an external guide rail or a guided cylinder to absorb lateral forces. If your application requires less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N.
This model features a PT G1/2 port and a 25 mm rod. It serves as a dimensionally interchangeable drop-in replacement for any standard ISO 15552 cylinder. Mounting accessories include FA/FB 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 SAI100BX500 FAQ
At 0.5 MPa, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force.
No, the standard SAI cylinder will drift if pressure is lost. For fail-safe load holding, use the SAIL variant with an air-released lock or an external rod lock.
