About the Airtac SAI63 Standard Cylinder SAI63X500S
The AirTAC SAI63X500-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 500mm stroke. It generates a push force of 1559 N and a pull force of 1402 N at 0.5 MPa, making it well-suited for mid-range automation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior while maintaining strict dimensional interchangeability with standard ISO 15552 cylinders.
Equipped with a magnet (-S), this model directly supports CMSE and DMSE reed switches via the integrated sensor grooves on both sides of the barrel. The standard configuration utilizes a carbon steel piston rod and a PT tapered port thread. For environments requiring higher thermal resistance, the seal options can be upgraded from standard TPU to Viton (H).

Where the Airtac SAI63 Standard Cylinder SAI63X500S Is Used
Material Handling
Drives 500mm stroke diverters and indexing mechanisms on packaging lines, utilizing the 1559 N push force to reliably shift medium-weight goods.
Automated Assembly
Extends tooling platforms to specific workstations, leveraging the built-in magnet and CMSE sensors for exact end-of-stroke position verification.
Vertical Lifting
Raises lightweight pallet stops and gating mechanisms, though external guidance is essential over this 500mm span to prevent rod deflection.
Is the Airtac SAI63 Standard Cylinder SAI63X500S the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm option is appropriate when you need more thrust than 982 N at 0.5 MPa, but want to avoid the bulk of the 80mm bore which yields 2513 N. The 500mm stroke falls within the 1500mm maximum standard limit for this bore. However, at this extended length, the unsupported rod is highly susceptible to bending under side loads. Implementing an external guide rail or choosing a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, this unit serves as a seamless drop-in replacement for other ISO 15552 cylinders, matching standard mounting footprints like the FA flange or TC trunnion. It operates with PT tapered G3/8 ports and a M16x1.5 rod thread. Note that the adjustable air cushions only decelerate the piston near stroke ends; they do not lock the rod. If your application requires fail-safe load holding upon air loss, consider the SAIL lock variant or an external pilot-operated check valve.
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 SAI63X500S FAQ
At an operating pressure of 0.5 MPa, the SAI63X500-S generates a push force of 1559 N and a pull force of 1402 N. If pressure is increased to 0.7 MPa, the push force reaches 2182 N.
Yes, the SAI63X500-S is a genuine ISO 15552 profile cylinder. Its mounting interface and dimensions are interchangeable with other ISO 15552 standard cylinders, allowing for seamless drop-in replacement using existing FA flange or TC trunnion mounts.
