About the Airtac SAI63 Standard Cylinder SAI63X285CA
The AirTAC SAI63X285 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 285mm stroke. It delivers 1559N of push force at 0.5MPa, making it a robust choice for medium-duty automation. This specific 285mm stroke provides the exact travel needed for specialized material handling tasks.
Equipped with a standard carbon steel piston rod and PT tapered port threads, this unit integrates seamlessly into existing setups. The extruded aluminum barrel includes dual sensor grooves for CMSE or DMSE switches. Note that this configuration ships without a magnet (-S omitted) and uses a CA clevis mounting accessory for pivot mounting.

Where the Airtac SAI63 Standard Cylinder SAI63X285CA Is Used
Package Diverting
Provides the 285mm reach needed to push cartons smoothly across a diverter lane on a high-speed packaging line.
Component Ejection
Exerts 1559N of force at 0.5MPa to reliably knock finished metal parts out of a machining fixture.
Pallet Positioning
Stops and positions empty pallets at a staging zone before they enter an automated stretch wrapper.
Is the Airtac SAI63 Standard Cylinder SAI63X285CA the Right Cylinder?
If you need slightly less force, stepping down to a 50mm bore yields 982N at 0.5MPa. For heavier cycles, moving up to an 80mm bore provides 2513N. Because the 285mm stroke is near the maximum standard limit for this bore, long unsupported rods are susceptible to bending under side loads. Implement an external guide rail or select a guided cylinder to protect the rod bearing.
This model serves as a dimensionally interchangeable drop-in replacement per ISO 15552. To match this exact configuration, specify a 63mm bore, 285mm stroke, PT port thread, CA mounting accessory, and no magnet (-S omitted). Keep in mind that standard air cushions only decelerate the piston near stroke end; they do not hold a load. If your application requires position holding without live air pressure, consider the SAIL lock variant or an external rod lock.
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 SAI63X285CA FAQ
At 0.5MPa, the push force is 1559N and the pull force is 1402N. If you increase the operating pressure to 0.7MPa, it generates 2182N of push force.
Yes, the SAI63X285 is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile cylinders, provided you match the 63mm bore, 285mm stroke, and CA mounting dimensions.
