About the Airtac SAI63 Standard Cylinder SAI63X600S
The AirTAC SAI63X600-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 600mm stroke. It generates a push force of 1559 N at 0.5 MPa, making it well-suited for mid-range industrial actuation. The extruded aluminum barrel includes dual sensor grooves, and the integrated -S magnet allows direct mounting of CMSE or DMSE reed switches for precise end-of-stroke detection.
This variant is equipped with a standard carbon steel piston rod and PT G3/8 tapered port threads. Adjustable air cushions at both ends decelerate the piston over a 36 mm stroke length, effectively dampening kinetic energy at operating speeds up to 800 mm/s.

Where the Airtac SAI63 Standard Cylinder SAI63X600S Is Used
Automated Material Handling
Drives long-travel lifting and pushing movements on packaging lines where a 1559 N push force at 0.5 MPa is sufficient to shift medium-weight product loads.
Assembly Line Indexing
Indexes pallets or workpieces along a 600mm travel path, utilizing the adjustable 36mm end cushions to ensure smooth stops without heavy impact.
Logistics Sortation
Actuates diverter arms in conveyor sortation systems, relying on the -S magnet and CMSE switches to confirm full extension and retraction to the control system.
Is the Airtac SAI63 Standard Cylinder SAI63X600S the Right Cylinder?
When sizing this actuator, stepping down to a 50mm bore reduces the push force to 982 N at 0.5 MPa, while an 80mm bore increases it to 2513 N. Because the 600mm stroke creates a long unsupported rod extension, side loads will induce bending moments on the rod bearing. For such extended strokes, utilize an external guide rail or a guided cylinder to prevent premature wear.
This profile cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other standard ISO 15552 profile cylinders. To hold a load securely when air pressure is exhausted or the valve is centered, select the SAIL (air-released lock) or BSAI (clamp-lock) variant instead of relying on the cushion, which only decelerates the piston.
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 SAI63X600S FAQ
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. If higher pressure is available, the push force increases to 2182 N at 0.7 MPa and 2805 N at 0.9 MPa.
Yes, the SAI63X600-S is a genuine ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 standard actuators of the same bore and stroke, utilizing a G3/8 PT port and standard mounting interfaces.
