About the Airtac SAI50 Standard Cylinder SAI50AX45
The AirTAC SAI50X45 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 45 mm stroke is optimal for short-travel clamping and indexing tasks. Built with an extruded aluminum barrel, this tie-rod-less design ensures direct dimensional interchangeability with other ISO 15552 standard cylinders.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance in mildly aggressive environments. Fluid supply connects via PT tapered thread ports. Because no magnet is specified, this base unit does not support direct piston sensing via reed or solid-state switches.

Where the Airtac SAI50 Standard Cylinder SAI50AX45 Is Used
Short-Stroke Clamping
Ideal for holding lightweight metal or plastic workpieces securely during secondary machining operations.
Package Diverting
Provides rapid actuation for pusher arms sorting small to medium packages on packaging lines.
Gate Control
Reliably drives small access gates or machine safety covers that require a compact 45 mm travel distance.
Is the Airtac SAI50 Standard Cylinder SAI50AX45 the Right Cylinder?
Selecting this 50 mm bore over the smaller 40 mm variant upgrades your thrust from 628 N to 982 N at 0.5 MPa, while stepping up to a 63 mm bore yields 1559 N. The 45 mm stroke keeps the assembly highly compact, minimizing mechanical envelope footprint.
If your workflow requires the piston to hold a load during a complete loss of air pressure, note that the standard adjustable air cushions only decelerate the rod near stroke end. For secure position holding, consider the SAIL variant with an air-released lock, or the BSAI bidirectional clamp-lock cylinder.
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.
