About the Airtac SAI50 Standard Cylinder SAI50X90
The AirTAC SAI50X90 is a double-acting ISO 15552 profile cylinder engineered to deliver a reliable push force of 982 N at 0.5 MPa. Its 90 mm stroke provides the precise mid-range extension needed for clamping, lifting, and positioning tasks in automated machinery.
Constructed with an extruded aluminum barrel, this unit features standard carbon steel piston rod material for robust durability. It incorporates adjustable air cushioning at both ends to absorb impact, and the barrel includes dual sensor grooves allowing for easy installation of CMSE or DMSE switches when position feedback is required.

Where the Airtac SAI50 Standard Cylinder SAI50X90 Is Used
Automated Clamping
Provides 982 N of clamping force at 0.5 MPa to secure metal workpieces securely during CNC machining or welding operations.
Package Diverting
Utilizes its 90 mm stroke to quickly extend diverter arms on packaging lines, efficiently routing boxes at high speeds.
Material Lifting
Lifts lightweight mechanical components or sub-assemblies between manufacturing stations with a smooth, cushioned motion.
Is the Airtac SAI50 Standard Cylinder SAI50X90 the Right Cylinder?
Selecting this 50 mm bore unit offers a balanced step up from the 40 mm bore class, which provides 628 N of push force at 0.5 MPa, without jumping to the heavier 63 mm class. The 90 mm stroke is ideal for compact cycles where space is limited but substantial thrust is still necessary.
This cylinder uses a PT tapered G1/4 port thread and is dimensionally interchangeable per ISO 15552 standards, making it a direct replacement for other ISO 15552 profile cylinders. If your application requires the load to remain held without continuous air pressure, pair this cylinder with an external pilot-operated check valve or transition to the SAIL locking variant.
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.
