About the Airtac SAI63 Standard Cylinder SAI63X470TC
The AirTAC SAI63X470 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559N of push force at 0.5 MPa. Its 470mm stroke is well-suited for mid-range linear actuation tasks requiring substantial travel. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration features a standard carbon steel piston rod and a PT tapered G3/8 port. Because it lacks a magnetic piston, it is optimized for pure pneumatic positioning rather than electronic switch tracking. For applications demanding end-position sensing, the -S variant with dual-side sensor grooves for CMSE or DMSE switches would be required.

Where the Airtac SAI63 Standard Cylinder SAI63X470TC Is Used
Automated Material Lift
Provides the 1559N push force necessary to elevate heavy workpieces along a 470mm vertical travel path in automated machining centers.
Pallet Transfer Gate
Actuates a diverter gate on a packaging line, utilizing the TC trunnion mount to absorb pivoting stresses during high-speed pallet routing.
Long-Stroke Ejection
Employs its 470mm stroke to push completed parts safely out of a large press bed before the next cycle begins.
Is the Airtac SAI63 Standard Cylinder SAI63X470TC the Right Cylinder?
Selecting this 63mm bore over the smaller 40mm option makes sense when you need to step up from 628N to 1559N of thrust at 0.5 MPa. The 470mm stroke falls comfortably within the 1500mm maximum standard stroke limit, but it is long enough to require careful consideration of mechanical stability. An unsupported rod of this length is susceptible to bending under side loads, so utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This model includes a TC trunnion mounting accessory, which allows the cylinder body to pivot and accommodate slight misalignments during operation. As a standard double-acting cylinder, it cannot hold a load in place if air pressure is lost or exhausted; the piston will drift. If your application requires true fail-safe load holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock 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 SAI63X470TC FAQ
At 0.5 MPa, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 2182N.
Yes. The SAI63X470 is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 cylinders. It is a drop-in replacement for standard ISO 15552 bodies.
