Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80S-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 80mm stroke and a built-in 4M210-08 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 SAUF32X80S-08A
The SAUF32X80S-08A is a double-acting profile cylinder with a built-in AirTAC 4M 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 1/8 inch cylinder port and an M10x1.25 rod thread.
This 32mm bore generates 402N push and 345N pull at 0.5MPa. The integrated 4M210-08 valve has a 1/4 inch port, Cv 0.89 flow, and handles 5 cycles/sec. The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0MPa, the valve limits operation to 0.15-0.8MPa. For sizing, the safe working load is about 241N, and vertical lift is roughly 20kg with a 2:1 margin. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAUF32X80S-08A Is Used
Decentralized Clamping
Ideal for a clamping station on a large machine. The integrated valve means one AC220V signal actuates the clamp directly without running long tubing to a central manifold.
Inline Diverting
Perfect for a small divert gate on a conveyor. The compact profile saves space while the 5 cycles/sec valve speed keeps pace with product flow.
Modular Pick & Place
Great for a modular pick and place unit. The built-in magnet lets you track position with CMSG switches while the self-contained valve simplifies controls.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X80S-08A the Right Choice?
Size force within the 0.15-0.8MPa valve window: this 32mm bore gives 402N push at 0.5MPa, while the neighbouring 40mm bore gives 628N. The 80mm stroke is above the 50mm minimum and below the 1000mm maximum, so no side-load guide is required. Confirm the AC220V terminal entry matches your supply. The rod retracts when the coil is energised; reposition the valve to reverse this to extend-when-energised. The built-in valve routes air and is not a load lock. For held loads, add an external rod lock or pilot-operated check valve. Mounting accessories are compatible with the AirTAC SC series.
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 SAUF32X80S-08A FAQ
It pushes 402N and pulls 345N at 0.5MPa. The built-in valve is a 4M210-08 (1/4 inch port, Cv 0.89, 5 cycles/sec). The coil is AC220V with terminal entry. Size force within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating.
By default the rod retracts when the coil is energised. You can reposition the valve to make it extend-when-energised. The valve only routes air; it is not a load lock. For loads that must be held without air, add an external rod lock or pilot-operated check valve.
