Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 350mm 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 SAUF32X350-08A
The SAUF32X350-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 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 makes it shorter than an ISO 15552 unit of the same bore. It has a 1/8" cylinder port and an M10x1.25 rod thread.
Operating strictly within the valve's 0.15-0.8 MPa window, this 32mm bore delivers 402N push and 345N pull at 0.5MPa. The 1/4" valve port yields a 16mm2 flow (Cv 0.89) and handles 5 cycles/sec. Computed buyer insight: safe working load is roughly 241N (60% of the 0.5MPa push), translating to a 20kg vertical lift with a 2:1 margin. This terminal-entry AC220V coil is IP65 rated. Since it lacks the -S suffix, this SKU cannot take 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 (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 SAUF32X350-08A Is Used
Decentralized Clamping
Ideal for distributed clamping stations where running individual lines to a central manifold is impractical, using the integrated valve for direct local control.
Inline Diverting
Drives a short-stroke diverter arm on a packaging line, switching itself with one AC220V signal to save tubing and installation time across long conveyors.
Modular Tooling
Perfect for interchangeable machine beds where each actuator must self-contain its 5/2 valve logic, freeing up manifold slots for other primary machine functions.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350-08A the Right Choice?
Size this 32mm bore against the 40mm option: the 40mm yields 628N push at 0.5MPa versus 402N here, while a smaller bore is unavailable in this family. Confirm the AC220V terminal entry matches your supply. Default action retracts the rod when energised; repositioning the valve switches it to extend-when-energised. Size force within the 0.15-0.8 MPa valve range, never the 1.0MPa cylinder body rating. The 4M210 valve only routes air, so add an external rod lock or pilot-operated check valve to hold loads. For the 350mm stroke, use external guides to prevent rod bending and 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 SAUF32X350-08A FAQ
It pushes 402N and pulls 345N at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) driven by an AC220V terminal-entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
No. The built-in 5/2 valve routes air but is not a lock; the piston will drift on air loss. For vertical holding you must add an external rod lock or pilot-operated check valve. Also note this non-S SKU cannot accept a magnetic sensor.
