Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350-08B is a genuine double-acting profile-type cylinder with a Ø40mm 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 SAUF40X350-08B
The SAUF40X350-08B 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 uses a Ø16 mm rod, M12x1.25 rod thread, and a 1/4" cylinder port.
Operating within the 0.15-0.8 MPa valve window, this 40 mm bore generates 628 N push and 528 N pull at 0.5 MPa. The integrated valve flows 16 mm2 (Cv 0.89) at up to 5 cycles per second. The DC24V terminal coil offers IP65 protection with a 0.05 s response. For sizing, the safe working load is roughly 377 N, and it can vertically lift about 32 kg with a 2:1 margin.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAUF40X350-08B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. The built-in 4M210-08 valve switches locally from one DC24V signal, eliminating long tube runs back to a central manifold.
Independent Clamping Station
Ideal for a standalone clamping actuator on a machining cell. It delivers 628 N of push at 0.5 MPa without consuming a slot on the main valve island, simplifying pneumatic plumbing.
Package Pusher Unit
Suits a localized package reject pusher. The integrated valve handles 5 cycles per second, providing rapid actuation right at the point of operation without remote valve lag.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X350-08B the Right Choice?
When sizing, compare neighbouring bores: a 32 mm bore yields 402 N push at 0.5 MPa, while a 50 mm bore provides 982 N, against this 40 mm bore's 628 N. Confirm the DC24V terminal entry and PT thread match your supply. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because this SKU lacks the -S magnet, it cannot accept a magnetic switch. For the 350 mm stroke, add external guides to prevent rod bending and side-load wear. The valve routes air but does not lock; add an external rod lock or pilot-operated check valve to hold loads.
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 SAUF40X350-08B FAQ
It generates 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89) running on DC24V. Although the cylinder body rates to 1.0 MPa, you must size force within the assembled valve's 0.15-0.8 MPa operating window.
The 5/2 valve routes air but does not lock the piston, so the load will drift on air loss; add an external rod lock or pilot-operated check valve for holding. The default action retracts when energised, but you can reconfigure it to extend-when-energised by repositioning the valve.
