Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X175S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X175S-08A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 175mm 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 SAUF63X175S-08A
The SAUF63X175S-08A is a double-acting profile-type cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The 63mm bore delivers 1559N push and 1402N pull at 0.5MPa, operating within the valve's 0.15-0.8MPa window. The cylinder body rates to 1.0MPa, but the assembled unit is limited by the valve. The 3/8" cylinder port and M16x1.5 rod thread handle robust decentralized tasks.
This unit features a piston magnet for CMSG/DMSG/EMSG switches. The integrated 4M310-08 valve offers 1/4" ports, 25mm2 flow (Cv 1.4), and 4 cycles/sec. From the 1559N push figure, the computed safe working load is 935N, and vertical lift is 79kg with a 2:1 margin. Terminal entry and IP65 coil protection suit industrial environments.

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 SAUF63X175S-08A Is Used
Package Diverter Gate
Uses one coil signal to actuate the diverter directly at the conveyor lane, eliminating long tubing runs back to a central manifold.
Machine Tool Clamp
Provides localized clamping force with its built-in 4M310-08 valve, simplifying the pneumatic layout on large machining centers.
Vertical Stopper Arm
Decentralized stopper mechanism leveraging the piston magnet for position feedback in high-density storage systems.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X175S-08A the Right Choice?
Size by checking both neighbor bores: the 50mm bore gives 982N push at 0.5MPa, while the 80mm bore gives 2513N, so this 63mm unit at 1559N fits mid-range. Always size force within the 0.15-0.8MPa valve operating range, never the 1.0MPa cylinder body rating. Confirm the AC220V terminal entry and PT thread meet your control specs. The rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. For load holding, the valve only routes air and is not a lock; add an external rod lock or pilot-operated check valve. For this 175mm stroke, side-load is minimal, but ensure proper guiding for longer strokes.
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 SAUF63X175S-08A FAQ
It delivers 1559N push and 1402N pull at 0.5MPa. The built-in valve is a 4M310-08 with 1/4" ports and Cv 1.4. The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0MPa, the assembled unit must operate in the 0.15-0.8MPa valve window.
By default the rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The valve routes air and is not a load lock; the piston will drift on air loss, so add an external rod lock or pilot-operated check valve for holding.
