About the Airtac SAI63 Standard Cylinder SAI63X450
The AirTAC SAI63X450 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 450mm stroke. It delivers a robust 1559N push force at 0.5MPa, making it highly suitable for medium-duty industrial handling and clamping tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that easily matches standard ISO 15552 mounting dimensions.
This specific configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because it lacks a built-in magnet (-S), it does not support direct sensor detection; if position feedback is needed, an -S variant with CMSE or DMSE switches is required. The cylinder also features adjustable air cushions at both ends to manage end-of-stroke impact.

Where the Airtac SAI63 Standard Cylinder SAI63X450 Is Used
Material Handling
Drives 450mm linear movements on packaging lines to push, lift, or divert medium-weight products between conveyors.
Workpiece Clamping
Generates 1559N of clamping force at 0.5MPa to securely hold components during machining or assembly processes.
Automated Gates
Actuates large safety guards or process doors, utilizing the full 450mm stroke to clear wide machine openings.
Is the Airtac SAI63 Standard Cylinder SAI63X450 the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm option upgrades your thrust from 982N to 1559N at 0.5MPa, while stepping up to the 80mm bore yields 2513N for heavier loads. The 450mm stroke provides ample travel for automated machinery, but long strokes require careful attention to side loads. An unsupported 450mm rod can bend under lateral forces, so utilizing an external guide rail or a guided cylinder mechanism is strongly recommended to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, the SAI63X450 is dimensionally interchangeable with other standard ISO 15552 cylinders, allowing for seamless drop-in replacements. Note that this standard cylinder will not hold its load if air pressure is lost or exhausted; the piston will drift. For applications requiring position holding without live pressure, 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.
