About the Airtac SAI63 Standard Cylinder SAI63BX500
The AirTAC SAI63X500 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 1559 N at 0.5 MPa. Its 500 mm stroke provides the extended travel needed for material handling and automated assembly tasks. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration incorporates a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and lacks a standard magnet. For operations requiring end-position locking without continuous air pressure, the SAIL variant provides a dedicated pneumatic locking mechanism.

Where the Airtac SAI63 Standard Cylinder SAI63BX500 Is Used
Long-Stroke Material Transfer
Pushes products between parallel conveyor lines over a 500 mm gap, utilizing the 1559 N thrust to overcome friction on heavy pallets.
Vertical Lift Stations
Elevates tote bins within storage racks; the SUS304 rod withstands potentially humid warehouse environments without surface degradation.
Automated Assembly Press
Drives sub-components into housings on an automated line, relying on adjustable air cushions to decelerate the 63 mm piston smoothly at stroke end.
Is the Airtac SAI63 Standard Cylinder SAI63BX500 the Right Cylinder?
Selecting this 63 mm bore unit makes sense when a 50 mm bore (982 N push at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (2513 N) would be physically oversized. At 500 mm of travel, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external linear guide or choose a guided cylinder module.
Because standard double-acting operation cannot hold a load safely upon air loss or valve centering, incorporate a pilot-operated check valve or specify the SAIL lock version for vertical loads. To match this exact ISO 15552 replacement, ensure the 63 mm bore, 500 mm stroke, G3/8 port, and appropriate mounting accessory (such as an LB foot or TC trunnion) are specified.
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 SAI63BX500 FAQ
At an operating pressure of 0.5 MPa, this 63 mm bore cylinder generates a push force of 1559 N and a pull force of 1402 N. If pressure increases to 0.7 MPa, the push force reaches 2182 N.
Yes, the SAI63X500 is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the 63 mm bore, 500 mm stroke, and G3/8 port layout without modifying the machine frame.
