Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X175-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X175-08A 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 SAUF63X175-08A
The SAUF63X175-08A is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. The bore dictates a 3/8" cylinder port and an M16x1.5 rod thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 1559 N push at 0.5 MPa. The integrated valve provides 25 mm2 flow (Cv 1.4) and handles up to 4 cycles per second. For sizing, the safe working load is roughly 935 N, and it can vertically lift about 79 kg with a 2:1 margin. This terminal-entry AC220V SKU lacks a magnet, so it cannot accept a magnetic switch.

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 SAUF63X175-08A Is Used
Sorting Diverter
Decentralized package sorting where one coil signal per diverter removes the need for a central valve manifold.
Clamp Station
Independent machine clamping on a large assembly line, saving tubing and simplifying installation.
Vertical Gate
Lifting a 79 kg gate with a 2:1 margin using local actuation without remote pneumatic routing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X175-08A the Right Choice?
Size force between the 0.15-0.8 MPa valve limits: this 63 mm bore pushes 1559 N at 0.5 MPa, sitting between the 50 mm (982 N) and 80 mm (2513 N) options. Confirm the AC220V terminal entry matches your control circuit. The rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 175 mm stroke, guide the load to prevent side-load wear.
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 SAUF63X175-08A FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa. The built-in 4M310-08 valve has a 1/4" port, Cv 1.4, and runs on AC220V. Size the assembled unit within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating.
The rod retracts by default when the coil is energised, but you can reposition the valve to extend instead. The valve only routes air; it is not a lock. The piston drifts on air loss, so fit an external rod lock or pilot-operated check valve for load holding.
