About the Airtac SAI63 Standard Cylinder SAI63AX800
The AirTAC SAI63X800 is a double-acting ISO 15552 profile cylinder featuring an 800 mm stroke and a 63 mm bore. It delivers a push thrust of 1559 N at 0.5 MPa, making it well-suited for long-travel material handling and robust positioning tasks.
This configuration includes a SUS420J2 stainless steel piston rod for enhanced corrosion resistance over standard carbon steel. The extruded aluminum barrel integrates sensor grooves on both sides, allowing direct mounting of CMSE or DMSE switches if a magnet is specified later.

Where the Airtac SAI63 Standard Cylinder SAI63AX800 Is Used
Long-Reach Transfer
Drives extended pushers across wide conveyor belts to shift heavy pallets between parallel packaging lines.
Large Press Feed
Advances sheet metal blanks into heavy stamping presses, utilizing the full 800 mm travel for deep reach.
Automated Storage
Actuates multi-axis gantry extractors to pull totes from high-density automated storage and retrieval systems.
Is the Airtac SAI63 Standard Cylinder SAI63AX800 the Right Cylinder?
With an 800 mm stroke, this cylinder operates at the upper end of the standard range for the 63 mm bore. If your application requires less force, stepping down to a 50 mm bore yields 982 N at 0.5 MPa, while moving up to an 80 mm bore provides 2513 N. Because the stroke is 800 mm, you must account for rod-bearing bending under side loads; utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature wear.
As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders for drop-in replacements. It uses a PT G3/8 port and supports standard mountings like FA flanges or TC trunnions. Note that the adjustable air cushions only decelerate the piston near the end of travel; they do not hold a load if air pressure is lost. For dead-stop holding, consider the SAIL or BSAI variants.
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.
