About the Airtac SAI63 Standard Cylinder SAI63AX700S
The AirTAC SAI63X700-S is a double-acting profile cylinder built to strict ISO 15552 dimensional standards, ensuring drop-in compatibility with other ISO 15552 interfaces. Delivering a push force of 1559 N at 0.5 MPa, this 63mm bore unit is equipped with a 700mm stroke, making it well-suited for automated handling tasks that require substantial travel distance.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. It also features a built-in magnet (-S) to operate seamlessly with CMSE and DMSE series solid-state switches mounted in the dual sensor grooves. The PT tapered air ports are sized at G3/8 to match the bore's flow requirements.

Where the Airtac SAI63 Standard Cylinder SAI63AX700S Is Used
Automated Stamping
Provides the 1559 N push force required to actuate stamping and forming presses over a long 700mm travel distance.
Pallet Transfer
Extends 700mm to push heavy pallets across transfer lines, utilizing its SUS420J2 rod to resist environmental moisture.
Multi-Tier Destacking
Handles component destacking from high vertical magazines where long reach and precise magnet-switch positioning are essential.
Is the Airtac SAI63 Standard Cylinder SAI63AX700S the Right Cylinder?
When specifying this model, verify that the 1559 N push force at 0.5 MPa is sufficient for your load; if higher thrust is needed, stepping up to the 80mm bore yields 2513 N. Because the 700mm stroke generates significant extension leverage, side loads can severely stress the rod bearing and cause premature wear. Employing an external linear guide or a guided cylinder carriage is strongly recommended to prevent rod bending.
This cylinder relies on live air pressure to maintain position; the adjustable air cushions at both ends only decelerate the piston near stroke completion and do not function as a locking mechanism. If your application requires fail-safe load holding during a pressure loss, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock series.
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.
