About the Airtac SAI63 Standard Cylinder SAI63X500
The AirTAC SAI63X500 is a double-acting ISO 15552 profile cylinder engineered for rigorous linear motion tasks. Operating at 0.5 MPa, it generates 1559 N of push force and 1402 N of pull force, making this 500 mm stroke variant well-suited for extended travel distances in automated assembly lines.
Built with an extruded aluminum barrel, the housing features integrated sensor grooves on both sides for direct CMSE or DMSE switch mounting. Customers can configure the piston rod with standard carbon steel, or upgrade to SUS420J2 or SUS304 stainless steel for corrosive environments. Standard NBR or TPU seals are available, alongside Viton options for high-temperature operations up to 70 C.

Where the Airtac SAI63 Standard Cylinder SAI63X500 Is Used
Material Transfer Gates
Leverages the 500 mm stroke to actuate large diverter gates across wide conveyor belts, effortlessly routing heavy packages with 1559 N of push force at 0.5 MPa.
Extended Stroke Ejection
Ideal for pushing machined components completely out of an enclosed workholding fixture, utilizing the full 500 mm travel to clear the machining envelope safely.
Pallet Positioning
Provides the robust 63 mm bore thrust necessary to shift or align heavy pallets at the end of packaging lines before stretch wrapping.
Is the Airtac SAI63 Standard Cylinder SAI63X500 the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm variant provides a significant thrust upgrade, stepping up from 982 N to 1559 N at 0.5 MPa. If your application requires even greater force, the 80 mm bore offers 2513 N under the same pressure. The G3/8 PT tapered port ensures optimal airflow for the 30-800 mm/s speed range.
Because this model features a 500 mm stroke, the extended rod is susceptible to bending under side loads. Implementing an external guide rail or utilizing a guided cylinder module is strongly recommended to prevent premature rod-bearing wear. Furthermore, the standard SAI does not maintain its position upon loss of air pressure; for suspended loads requiring fail-safe holding, integrate the SAIL (air-released lock) or BSAI (clamp-lock) variant. This unit serves as a dimensionally interchangeable drop-in replacement per ISO 15552 mounting interfaces.
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.
