About the Airtac SAI63 Standard Cylinder SAI63AX950
The AirTAC SAI63X950 is a double-acting ISO 15552 profile cylinder engineered for extended reach applications. Delivering a robust 1559 N of push force at 0.5 MPa, this non-standard 950 mm stroke unit is manufactured to order for specialized machinery. The extruded aluminum barrel design omits tie rods, providing a smooth, standardized mounting interface that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and lacks a standard magnet; if position sensing is later required, adding the -S option enables CMSE or DMSE switches to ride securely in the dual side sensor grooves. For operations needing bidirectional clamping without continuous air pressure, the related BSAI clamp-lock variant is available in this same 63 mm bore size.

Where the Airtac SAI63 Standard Cylinder SAI63AX950 Is Used
Extended Reach Forming
Handles long-stroke press operations and material forming tasks where a 950 mm reach is required to clear large tooling or workpieces.
Long-Range Transfer
Actuates large-span pushers on heavy-duty conveyor lines, moving pallets or structural components between processing stations.
High-Bay Actuation
Drives vertical lifting or lowering platforms in automated high-bay storage systems, utilizing its 1559 N thrust at 0.5 MPa.
Is the Airtac SAI63 Standard Cylinder SAI63AX950 the Right Cylinder?
Selecting this 950 mm stroke requires careful consideration of lateral forces, as long unsupported rods are highly susceptible to bending under side loads. To prevent premature rod-bearing wear and cylinder failure, implement an external linear guide or transition to a guided cylinder to manage the load entirely. If your application demands higher force, stepping up to the 80 mm bore yields 2513 N at 0.5 MPa; if less force is acceptable, the 50 mm bore provides 982 N at 0.5 MPa.
Because this is a 950 mm non-standard stroke configuration, expect a made-to-order lead time. The standard SAI cylinder relies on adjustable air cushions at both ends to decelerate the piston near stroke limits, but this cushioning does not lock or hold the load. If the mechanism must maintain its position safely upon loss of air pressure, integrate an external pilot-operated check valve or specify the SAIL air-released lock variant.
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.
