About the Airtac SAI50 Standard Cylinder SAI50X80S
The AirTAC SAI50X80-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 80 mm stroke provides a compact yet highly effective extension for mid-range automation tasks. The extruded aluminum barrel design eliminates tie-rods, offering a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
Equipped with a magnetic piston (-S), this unit supports direct mounting of CMSE or DMSE reed switches along the dual sensor grooves machined into both sides of the barrel. It features a durable carbon steel piston rod and standard TPU seals, ensuring reliable performance across its 30-800 mm/s operating speed range.

Where the Airtac SAI50 Standard Cylinder SAI50X80S Is Used
Component Clamping
Provides 825 N of pull force at 0.5 MPa, making it highly effective for securing medium-sized metal parts during machining or welding operations.
Package Diverting
The 80 mm stroke actuates diverter arms swiftly at speeds up to 800 mm/s to route parcels on high-throughput packaging lines.
Gate Control
Operates access gates and machine guarding doors, utilizing the magnetic piston to confirm open or closed positions via DMSE sensors.
Is the Airtac SAI50 Standard Cylinder SAI50X80S the Right Cylinder?
Selecting this 50 mm bore is ideal when an application requires stepping up from a 40 mm bore, which yields 628 N at 0.5 MPa, but does not warrant the 1559 N output of a 63 mm variant. The 80 mm stroke is optimal for short, rapid cycling without occupying excessive axial space. Because the stroke is under 300 mm, rod-bearing bending from side loads is minimal, though external guides should still be used to prevent binding if the load is off-center.
For dimensionally interchangeable ISO 15552 replacements, verify the 50 mm bore, 80 mm stroke, G1/4 PT port thread, and your required mounting accessory (such as LB foot or TC trunnion). If the machinery demands position holding upon air pressure loss, note that the standard adjustable air cushions only decelerate the piston at stroke ends and will not lock the load; consider the SAIL variant for pneumatic locking requirements.
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 SAI50X80S FAQ
At an operating pressure of 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X80-S is a genuine ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders, provided you match the 50 mm bore, 80 mm stroke, and G1/4 port.
