About the Airtac SAI63 Standard Cylinder SAI63AX105S
The AirTAC SAI63X105-S is a double-acting ISO 15552 profile cylinder engineered for mid-range automation tasks. It provides a robust push force of 1559 N and a pull force of 1402 N at 0.5 MPa, making it well-suited for a 105 mm stroke in moderate-load handling. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Equipped with a magnetic piston (-S), it supports direct mounting of CMSE or DMSE sensor switches in the dual side grooves. Fluid ports feature PT tapered threads, and the cylinder incorporates adjustable air cushions at both ends to smooth out stroke transitions.

Where the Airtac SAI63 Standard Cylinder SAI63AX105S Is Used
Component Ejection
Ideal for pushing machined metal parts out of a fixture, utilizing its 1559 N push force at 0.5 MPa to reliably overcome friction and eject heavy components.
Package Diverting
The 105 mm stroke provides the precise extension needed to actuate diverting arms on a packaging line, while the magnetic piston allows for exact position confirmation.
Pallet Lifting
Suitable for lifting lower-tier pallets or tote boxes in compact material handling stations where the 63 mm bore delivers sufficient thrust without excessive bulk.
Is the Airtac SAI63 Standard Cylinder SAI63AX105S the Right Cylinder?
Select this 63 mm bore when a 50 mm bore (delivering 982 N push at 0.5 MPa) lacks the necessary power, but an 80 mm bore (2513 N push) would be physically oversized. The 105 mm stroke hits a practical middle ground for compact ejection and lifting tasks. Because the stroke remains under 300 mm, standard rod bearing bending is minimal, though external guides should still be used for heavy off-center loads.
For applications requiring the load to be held in place during a complete loss of air pressure, note that the standard adjustable air cushion only decelerates the piston at stroke end and does not function as a brake. In those scenarios, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve. To match this unit exactly for an ISO 15552 replacement, confirm the 63 mm bore, 105 mm stroke, G3/8 port size, PT thread type, required mounting accessory (such as LB foot or TC trunnion), and the -S magnet option.
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 SAI63AX105S FAQ
Operating at 0.5 MPa, this 63 mm bore cylinder 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 rises to 2182 N.
Yes, the SAI63X105-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the 63 mm bore, 105 mm stroke, and G3/8 port locations, provided you account for the PT tapered port threads.
