About the Airtac SAI63 Standard Cylinder SAI63BX210S
The AirTAC SAI63X210-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. This specific 210 mm stroke configuration is a made-to-order non-standard length, providing extended travel for automated machinery while maintaining strict ISO 15552 mounting interchangeability.
Because this unit carries the -S suffix, it includes an integrated magnet for non-contact position sensing using CMSE or DMSE series switches along the dual sensor grooves. Furthermore, this configuration features a SUS304 stainless steel piston rod (option B), offering superior corrosion resistance compared to standard carbon steel, making it well-suited for humid or chemically exposed environments.

Where the Airtac SAI63 Standard Cylinder SAI63BX210S Is Used
Extended Travel Assembly
Ideal for automated lines requiring a 210 mm reach to position components accurately without compromising on the 1559 N push force.
Corrosive Environment Actuation
The SUS304 stainless steel rod makes this cylinder highly suitable for packaging lines or environments exposed to washdowns and moisture.
Pallet Pushing
Provides reliable lateral pushing force to divert or stage pallets on conveyors, utilizing the integrated magnet for timing confirmation.
Is the Airtac SAI63 Standard Cylinder SAI63BX210S the Right Cylinder?
Choosing this bore size provides a balanced thrust output of 1402 N on the pull side at 0.5 MPa. If your application demands less force, stepping down to a 50 mm bore yields 982 N push force, whereas upgrading to an 80 mm bore provides 2513 N. When integrating this cylinder, remember that the adjustable air cushions at both ends only serve to decelerate the piston near stroke ends; they do not lock or hold a load. If your machinery loses air pressure, the rod will drift. For fail-safe load holding without live pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants.
This 210 mm stroke exceeds the standard catalog increments, so it is manufactured as a special order. For strokes of 300 mm or longer, side loads can cause excessive bending stress on the rod bearing. In those extended cases, an external guide rail or a fully guided cylinder is strongly recommended to prevent premature wear. This model utilizes PT tapered port threads (G3/8) and is fully interchangeable with any ISO 15552 footprint cylinder.
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 SAI63BX210S FAQ
At a standard 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes. The SAI series is a true ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 compliant cylinders. You can drop it into existing FA/FB flange or TC trunnion setups seamlessly.
