About the Airtac SAI50 Standard Cylinder SAI50AX750S
The AirTAC SAI50X750-S is a double-acting ISO 15552 profile cylinder engineered for a 750mm stroke. It generates 982N of push force at 0.5 MPa and 1374N at 0.7 MPa, making it suitable for long-travel material handling. The extruded aluminum barrel eliminates tie rods while maintaining strict dimensional interchangeability for global standardization.
This specific configuration includes a SUS420J2 stainless steel piston rod for superior corrosion resistance in humid environments. Equipped with a magnetic piston (-S), it supports direct mounting of CMSE and DMSE sensor switches along the dual grooves on the barrel. Ports feature PT tapered threading, and adjustable air cushions at both ends manage end-of-stroke impact.

Where the Airtac SAI50 Standard Cylinder SAI50AX750S Is Used
Long-Travel Conveying
Drives 750mm stroke pushers on packaging lines to transfer products between adjacent conveyor belts.
Pallet Handling
Utilizes 982N of thrust at 0.5 MPa to index heavy pallets into automated storage and retrieval systems.
Automated Door Actuation
Opens and closes large industrial machine safety doors over a 750mm travel distance using SUS420J2 rod corrosion resistance.
Is the Airtac SAI50 Standard Cylinder SAI50AX750S the Right Cylinder?
Selecting this 50mm bore is ideal when 40mm cylinders (providing 628N at 0.5 MPa) lack the necessary thrust, but a 63mm bore (1559N) would be physically oversized. The 750mm stroke falls within the standard 1200mm maximum for this bore.
Because the stroke is 750mm, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, guide external loads using linear rails or select a guided cylinder. Note that a standard SAI does not maintain position or hold a load if air pressure is lost; for fail-safe holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. As a genuine ISO 15552 profile cylinder, it serves as a direct replacement for other standard cylinders with identical 50mm bore, 750mm stroke, PT G1/4 port, and FA/FB flange or TC trunnion mounts.
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 SAI50AX750S FAQ
The SAI50X750-S cylinder provides 982N of push force and 825N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 1374N.
Yes. As a genuine ISO 15552 profile cylinder, its mounting interface is dimensionally interchangeable with other ISO 15552 cylinders of the same 50mm bore, 750mm stroke, and G1/4 port size.
