About the Airtac SAI50 Standard Cylinder SAI50BX75
The AirTAC SAI50X75 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 75mm stroke. It delivers a push force of 982N at 0.5MPa, making it well-suited for mid-range industrial handling tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists mechanical impact.
This specific unit is configured with a SUS304 stainless steel rod for superior corrosion resistance in harsh or washdown environments. It utilizes PT tapered port threads, and because no magnet is specified, it operates without electronic position sensing.

Where the Airtac SAI50 Standard Cylinder SAI50BX75 Is Used
Component Clamping
Secures steel machined parts during milling operations with 982N of clamping force at 0.5MPa.
Package Diverting
Actuates a routing arm on a packaging line to sort products into secondary chutes.
Material Ejection
Pushes finished molded components out of a hydraulic press area safely and efficiently.
Is the Airtac SAI50 Standard Cylinder SAI50BX75 the Right Cylinder?
If your application requires less energy, the 40mm bore variant offers 628N of push force at 0.5MPa. For heavier payloads, stepping up to the 63mm bore yields 1559N. Because this is a standard 75mm stroke, side-load stress on the rod bearing is minimal.
The SAI50X75 serves as a dimensionally interchangeable direct replacement per ISO 15552 standards. When replacing, verify the 50mm bore, 75mm stroke, PT G1/4 port, and your required mounting accessory. Remember that standard double-acting cylinders drift when air pressure is removed; utilize an external pilot-operated check valve if the load must be held vertically.
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.
