About the Airtac SAI100 Standard Air Cylinder SAI100BX145
The AirTAC SAI100X145 is a double-acting profile cylinder built to ISO 15552 dimensional standards, providing a drop-in mounting interface for universal compatibility. Delivering a robust 3927 N of push force at 0.5 MPa, it is engineered for heavy-duty automation tasks requiring a 145 mm stroke.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in harsh environments. It utilizes tapered PT port threads and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX145 Is Used
Heavy-Duty Stamping
Provides the substantial 3927 N push force required to form and stamp thick-gauge metal components in automated production lines.
Large Material Pressing
Ideal for pressing composite materials or large bearings into heavy housings, utilizing the exact 145 mm stroke for deep reach.
Pallet Diversion
Actuates heavy-duty routing gates on high-capacity conveyor systems to divert loaded pallets weighing several hundred kilograms.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX145 the Right Cylinder?
Providing 3927 N at 0.5 MPa, this 100 mm bore is a significant step up from the 63 mm bore class, which yields 1559 N. If your application requires less force, dropping to the 80 mm bore (2513 N) can save space and air consumption. Because the 145 mm stroke is a non-standard made-to-order length, ensure your delivery timeline accommodates custom manufacturing.
For installations needing fail-safe load holding when air pressure is lost, do not rely on the SAI's adjustable air cushions, as they only decelerate the piston near the end of travel. Instead, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. This model's ISO 15552 interface ensures seamless physical interchangeability with other standard profile cylinders of the same bore size.
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.
