About the Airtac SAI63 Standard Cylinder SAI63BX450
The AirTAC SAI63X450 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 450 mm stroke provides the extended travel needed for mid-distance indexing and automated handling tasks.
This specific configuration utilizes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. It features PT tapered port threads and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not enabled for this unit.

Where the Airtac SAI63 Standard Cylinder SAI63BX450 Is Used
Long-Reach Clamping
Extends 450 mm to secure large workpieces inside machining centers, using the 1559 N thrust to hold parts firmly against fixtures.
Pallet Transfer
Pushes heavy pallets across automated conveyor lines over mid-range distances where a shorter stroke would fall short.
Material Ejection
Ejects molded or stamped components from machinery, relying on the SUS304 rod to withstand occasional abrasive contact.
Is the Airtac SAI63 Standard Cylinder SAI63BX450 the Right Cylinder?
Selecting this 63 mm bore over a smaller 50 mm option upgrades your thrust from 982 N to 1559 N at 0.5 MPa, while stepping up to an 80 mm bore yields 2513 N. Because this model features a 450 mm stroke, the unsupported rod length is susceptible to bending under side loads; utilize external guide rails or a guided cylinder to prevent rod-bearing damage.
As an ISO 15552 profile cylinder, it drops directly into existing mounting footprints using standard LB, FA, or TC accessories. If your mechanism must hold a load vertically without continuous air pressure, note that standard air cushions only decelerate the piston at end-of-stroke and do not function as a brake; specify an SAIL or BSAI locking variant for fail-safe holding.
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 SAI63 Standard Cylinder SAI63BX450 FAQ
At an operating pressure of 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes. The SAI63X450 is built to the ISO 15552 dimensional standard, making it interchangeable with other ISO 15552 profile cylinders of the same bore and stroke. Just match your existing PT port and mounting accessories.
