About the Airtac SAI50 Standard Cylinder SAI50AX75
The AirTAC SAI50X75 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 75mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, making it well-suited for mid-range industrial positioning tasks.
This model features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes tapered PT port threads. The extruded aluminum barrel includes dual sensor grooves, allowing direct mounting of CMSE or DMSE switches if a magnet is added later.

Where the Airtac SAI50 Standard Cylinder SAI50AX75 Is Used
Component Ejection
Provides reliable push force to eject finished parts from machining centers or molding presses.
Package Diverting
Actuates diverting arms on packaging lines to route boxes to specific sorting lanes.
Material Grippers
Drives external gripper mechanisms to clamp and transfer workpieces between robotic stations.
Is the Airtac SAI50 Standard Cylinder SAI50AX75 the Right Cylinder?
Choose this 50mm bore when a 40mm cylinder lacks sufficient thrust—upgrading from the 40mm bore yields 628N at 0.5 MPa, while stepping up to a 63mm bore provides 1559N for heavier payloads. The 75mm stroke is optimal for compact cycles requiring fast, repeatable extension.
Because this is a standard double-acting cylinder, it relies on continuous air pressure to hold position; if your application requires static load holding during pressure loss, consider the SAIL variant with an air-released lock. As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard 50mm bore ISO 15552 unit with a G1/4 port and 20mm rod thread.
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 SAI50 Standard Cylinder SAI50AX75 FAQ
At an operating pressure of 0.5 MPa, the SAI50X75 generates 982N of push force and 825N of pull force. At 0.7 MPa, the push force increases to 1374N.
Yes, the SAI50X75 is dimensionally interchangeable per ISO 15552. Its standardized mounting interface, 20mm rod, and G1/4 port allow it to serve as a direct replacement for equivalent 50mm ISO 15552 profile cylinders.
