About the Airtac SAI100 Standard Air Cylinder SAI100BX170S
The AirTAC SAI100X170-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust push force of 3927 N at 0.5 MPa, making it well-suited for high-thrust pressing and heavy load handling over its 170 mm travel. The extruded aluminum barrel design strictly adheres to standardized ISO 15552 mounting dimensions, ensuring seamless drop-in compatibility with other global ISO 15552 cylinders.
This specific configuration includes a SUS304 stainless steel rod (material code B) for superior corrosion resistance in harsh environments. It features PT tapered port threads and is equipped with a magnet (-S) to operate CMSE or DMSE reed switches. The dual-sided sensor groove on the barrel allows for highly flexible switch mounting, while adjustable air cushions at both ends effectively decelerate the piston to minimize end-cap impact.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX170S Is Used
Heavy-Duty Pressing
Ideal for stamping, riveting, and assembling dense metal components where a reliable 3927 N thrust at 0.5 MPa is required for consistent forming pressure.
Pallet Stopping
Functions as a robust stopper block on heavy-load conveyor lines, using its 170 mm stroke to halt large pallets securely without exceeding standard stroke limits.
Automated Clamping
Provides rigid, high-force clamping of large workpieces during CNC machining or welding operations, with the SUS304 rod offering resilience against coolant splashes.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX170S the Right Cylinder?
Choose this 100 mm bore when 50 mm or 63 mm models lack the necessary thrust—stepping down to a 63 mm bore reduces the 0.5 MPa push force to 1559 N, whereas this 100 mm bore provides 3927 N. For applications requiring even greater force, the 125 mm bore offers 6136 N at the same pressure. The 170 mm stroke is well within standard limits, but if your application involves heavy side loads, consider using an external guide rail or a guided cylinder to prevent rod-bearing bending and premature wear.
This standard double-acting cylinder relies on live air pressure to maintain its position; if air is exhausted or the valve is centered, the piston will drift. The adjustable air cushion only decelerates the piston near the stroke ends and does not function as a locking mechanism. If your machinery requires true position holding without live pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. For exact ISO 15552 replacement matching, verify the 100 mm bore, 170 mm stroke, G1/2 port, and required mounting accessories (such as FA/FB flanges or TC trunnions).

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 SAI100BX170S FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore double-acting cylinder generates a push force of 3927 N and a pull force of 3681 N. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
No, the standard SAI cylinder is double-acting and will drift if air pressure is removed or the directional valve is centered. The adjustable air cushions only slow the piston at stroke end and do not lock the load. For fail-safe holding, use the SAIL (air-released lock) or BSAI (clamp-lock) variants.
