About the Airtac SAI50 Standard Cylinder SAI50X30
The AirTAC SAI50X30 is a double-acting ISO 15552 profile cylinder engineered for short-stroke automation. Delivering a push force of 982 N at 0.5 MPa, it fits perfectly into compact assemblies requiring rapid, high-impact actuation.
This unit features a standard carbon steel piston rod and PT tapered port threads. The extruded aluminum barrel incorporates dual sensor grooves, allowing you to mount CMSE or DMSE switches directly if a magnet is added later.

Where the Airtac SAI50 Standard Cylinder SAI50X30 Is Used
Short-Stroke Clamping
Ideal for holding parts securely during machining or welding operations where a fast, hard clamping force is needed.
Package Diverting
Provides rapid actuation for sorting arms or pop-up gates on high-speed packaging lines.
Ejector Mechanisms
Delivers the immediate impact required to eject finished parts from press beds or molding machines.
Is the Airtac SAI50 Standard Cylinder SAI50X30 the Right Cylinder?
Choose this 50 mm bore when a 40 mm cylinder lacks sufficient thrust (628 N at 0.5 MPa) but a 63 mm unit provides unnecessary excess. For this short 30 mm stroke, side-load stress on the rod bearing is minimal, making it ideal for high-speed cycling.
Remember that standard air cushions only decelerate the piston near the end of travel; they do not hold a load. If your fixture must maintain position after a pressure loss, integrate an external pilot-operated check valve. This model is dimensionally interchangeable per ISO 15552, accepting standard LB foot or FA flange 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 SAI50X30 FAQ
