About the Airtac SAI50 Standard Cylinder SAI50X90S
The AirTAC SAI50X90-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982N of push force and 825N of pull force at 0.5 MPa. With a 50mm bore and 90mm stroke, it provides an optimal motion envelope for mid-range automation tasks.
This variant includes a standard carbon steel piston rod and a built-in magnet for seamless integration with CMSE and DMSE reed switches via the dual sensor grooves on the extruded aluminum barrel. It features a tapered PT G1/4 port and adjustable air cushions at both ends to manage impact at stroke extremes.

Where the Airtac SAI50 Standard Cylinder SAI50X90S Is Used
Component Clamping
Secures medium-sized metal or plastic parts during machining and assembly operations using its 982N push force.
Package Diverting
Actuates routing gates and pushers on packaging lines with precise 90mm stroke movements.
Material Ejection
Ejects molded or stamped products from machinery quickly, utilizing the adjustable end cushions to soften stopping impact.
Is the Airtac SAI50 Standard Cylinder SAI50X90S the Right Cylinder?
If your application requires slightly less output, stepping down to the 40mm bore yields 628N of push force at 0.5 MPa, while moving up to the 63mm bore provides 1559N for heavier payloads. The 90mm stroke is highly versatile, but if your mechanism experiences significant lateral loads, consider utilizing external guide rails or a guided cylinder to prevent rod-bearing wear.
Because this is a standard double-acting actuator, air pressure is required to maintain rod position; exhausting the circuit or centering the directional valve will cause the piston to drift. For tasks that must hold a load safely without live pressure, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead. As a true ISO 15552 profile cylinder, it offers direct dimensional interchangeability with other ISO 15552 actuators using standard FA, LB, or TC mounting accessories.
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 SAI50X90S FAQ
