About the Airtac SAI63 Standard Cylinder SAI63AX1000S
The AirTAC SAI63X1000-S is a double-acting ISO 15552 profile cylinder engineered for long-traverse automation tasks. It provides a robust 1559 N push force at 0.5 MPa, making it well-suited for moving moderate loads across a 1000 mm span. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that resists mechanical interference.
Configured with an integrated magnet for CMSE or DMSE reed switches, this specific model utilizes SUS420J2 stainless steel for the piston rod (option A) to enhance durability against moisture. It also features PT tapered port threads and adjustable air cushions at both ends to manage deceleration over the extended travel distance.

Is the Airtac SAI63 Standard Cylinder SAI63AX1000S the Right Cylinder?
A 63 mm bore provides 1559 N of push force at 0.5 MPa. If your assembly requires less thrust, stepping down to the 50 mm bore yields 982 N; conversely, upgrading to the 80 mm bore provides 2513 N for heavier payloads. Because this unit features a 1000 mm stroke, side loading is a primary concern. An unsupported rod of this length is highly susceptible to bending under lateral stress; always utilize external guide rails or a dedicated guided cylinder to support the load and prevent premature rod-bearing failure.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other standard profile cylinders. To match this exact configuration, specify the 63 mm bore, 1000 mm stroke, PT G3/8 port, TC trunnion or FA flange mounting, and the -S magnet option. Note that standard air cushions only decelerate the piston near stroke end; they do not hold a load. If pressure is lost, the rod will drift, requiring an external pilot-operated check valve or the SAIL locking variant for true position holding.
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.
