About the Airtac SAI63 Standard Cylinder SAI63AX600
The AirTAC SAI63X600 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559N of push force at 0.5MPa. Featuring a 600mm stroke, it bridges the gap between mid-range and large-scale automation tasks. The extruded aluminum barrel design omits traditional tie-rods, providing a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration is built with a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance in humid or mildly chemically exposed environments. It utilizes PT tapered port threads and lacks a magnet, meaning it is optimized for pure pneumatic actuation without requiring hall-effect position sensing.

Where the Airtac SAI63 Standard Cylinder SAI63AX600 Is Used
Material Transfer
Pushes heavy pallets or workpieces along a 600mm transfer distance, utilizing the 1559N force to overcome friction on roller conveyors.
Packaging Equipment
Actuates long-travel folding arms or sealing mechanisms in continuous packaging lines where a 63mm bore provides optimal thrust.
Assembly Line Jigs
Drives large positioning jigs over a 600mm span, relying on the SUS420J2 rod to resist corrosion in environments with cutting fluids.
Is the Airtac SAI63 Standard Cylinder SAI63AX600 the Right Cylinder?
At 0.5MPa, this 63mm bore yields 1559N of push force; if your application requires less force, stepping down to a 50mm bore provides 982N, conserving compressed air. For longer strokes like this 600mm unit, side loads pose a significant risk of bending the rod bearing and causing premature seal wear. Implementing an external guide rail or utilizing a guided cylinder is strongly recommended to absorb lateral forces.
Because this is a standard double-acting cylinder, the adjustable air cushions at both ends only serve to decelerate the piston near the stroke limits. If your machinery must hold a load statically without continuous air pressure, you must integrate an external pilot-operated check valve or select the SAIL variant with an air-released lock. To match this ISO 15552 footprint, ensure your mounting accessory (LB, FA, or TC) matches the 63mm interface and use PT threaded fittings.
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.
