Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X100S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X100S-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 100mm stroke and a built-in 4M310-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X100S-08B
The SAUF63X100S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 63mm bore delivers 1559N push and 1402N pull at 0.5MPa. The cylinder body rates to 1.0MPa, but the assembled unit operates strictly within the 0.15-0.8MPa valve window.
The integrated valve provides 1/4" porting with a 25mm2 flow (Cv 1.4) and cycles up to 4 times per second. It includes a piston magnet for CMSG/DMSG/EMSG switches. For sizing, the safe working load is roughly 935N (about 60% of the 0.5MPa push force), translating to a vertical lift capacity of approximately 79kg with a 2:1 margin. The cylinder features a 3/8" air port, an M16x1.5 rod thread, and adjustable cushions.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF datasheet. Port options: PT / G.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X100S-08B Is Used
Decentralized Clamping Station
Ideal for a machining cell where each clamp needs its own DC24V signal without running tubing back to a central manifold.
Independent Divert Gate
Uses the built-in 4M310 valve to actuate a sorting gate directly at the lane, saving space and simplifying installation.
Localized Lift Stopper
Perfect for lifting a 79kg pallet load in a compact zone, utilizing the integrated magnet for position feedback.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X100S-08B the Right Choice?
Size by comparing neighbouring bores: the 50mm bore offers 982N push at 0.5MPa, while the 80mm bore provides 2513N. This 63mm unit outputs 1559N push at 0.5MPa. Always size force within the 0.15-0.8MPa valve operating range, never the 1.0MPa cylinder body rating. Confirm the DC24V terminal entry and PT thread match your control setup. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For this 100mm stroke, side-load guides are not strictly required but ensure standard SC-series mounting accessories are used.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X100S-08B FAQ
It delivers 1559N push and 1402N pull at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/s max) driven by a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window.
No, the built-in valve only routes air and is not a lock. The default action retracts the rod when energised, which can be reconfigured to extend by repositioning the valve. For load holding on air loss, install an external rod lock or pilot-operated check valve.
