About the Airtac SAI100 Standard Air Cylinder SAI100BX155
The AirTAC SAI100X155 is a double-acting ISO 15552 profile cylinder engineered to deliver 3927 N of push force at 0.5 MPa. With a 100 mm bore and 155 mm stroke, it provides the robust thrust needed for heavy-duty positioning and clamping tasks. The extruded aluminum barrel design omits tie-rods, yielding a cleaner profile that matches standardized ISO 15552 mounting dimensions.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in washdown or chemically active settings. It utilizes PT tapered port threads and lacks a magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification. For higher temperature environments up to +70 C, the standard TPU seals can be swapped for Viton (H) or NBR (N) alternatives.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX155 Is Used
Heavy-Duty Stamping
Provides 3927 N of thrust at 0.5 MPa for securely pressing metal or plastic components into rigid fixtures.
Automated Assembly Press
Drives high-force insertion pins and riveting heads with a 155 mm stroke, utilizing SUS304 rod durability.
Pallet Handling Stops
Acts as a robust physical stop mechanism for heavy pallets on conveyor lines, absorbing impact via end cushions.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX155 the Right Cylinder?
Choosing this 100 mm bore over the smaller 80 mm variant upgrades your thrust from 2513 N to 3927 N at 0.5 MPa, while stepping up to the 125 mm bore yields 6136 N. The 155 mm stroke falls below the 300 mm threshold, so rod-bearing bending from side loads is less critical, though external guides are always recommended if offset loads are present. Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops; the adjustable air cushions only decelerate the piston at stroke ends. For fail-safe position holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. As a true ISO 15552 cylinder, it serves as a drop-in replacement for any standard 100 mm bore, 155 mm stroke unit with a G1/2 port and standard FA, LB, or TC mounting accessories.
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 SAI100BX155 FAQ
At 0.5 MPa operating pressure, the SAI100X155 generates 3927 N of push force and 3681 N of pull force. At the maximum standard pressure of 1.0 MPa, the theoretical push force reaches 801 kgf.
Yes, the SAI100X155 is dimensionally interchangeable per ISO 15552 standards. It matches the mounting interface, G1/2 port size, and 155 mm stroke of other profile cylinders, allowing a seamless drop-in replacement.
