Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-08B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 150mm 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 SAUF40X150-08B
The SAUF40X150-08B 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 is shorter than an ISO 15552 unit of the same bore. This bore uses a 1/4" cylinder port, a Ø16 mm rod, and M12x1.25 rod-end thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 628 N push and 528 N pull at 0.5 MPa. The DC24V terminal-entry coil offers IP65 protection and a 0.05 s response. The 4M210-08 valve provides 16 mm2 flow (Cv 0.89) at up to 5 cycles/s. For sizing, expect a safe working load of roughly 377 N, or a 32 kg vertical lift with a 2:1 margin. This 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 (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 SAUF40X150-08B Is Used
Divert Gate Actuation
Decentralized package routing on a conveyor, where the integrated valve switches the diverter instantly without a central manifold.
Clamp Station Control
Independent clamping on an assembly cell, using the single coil signal to actuate the 150 mm stroke directly at the point of operation.
Machine Tool Loading
Pushing parts into a machining center, saving tubing and installation time by mounting the 4M210-08 valve directly on the cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-08B the Right Choice?
Size force between the 32 mm bore (402 N push) and 50 mm bore (982 N push) at 0.5 MPa; this 40 mm bore yields 628 N push. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when the coil energises, but you can reposition the valve to extend on signal. Always size within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air but does not lock the piston; add an external rod lock or pilot-operated check valve for held loads. For this 150 mm stroke, ensure side-load guidance to prevent rod binding.
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 SAUF40X150-08B 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, 5 cycles/s). The DC24V coil runs the assembled unit at 0.15-0.8 MPa, despite the cylinder body rating to 1.0 MPa.
By default the rod retracts on signal, but repositioning the valve changes it to extend-when-energised. The valve only routes air; it is not a lock, so the piston drifts on air loss. Add an external rod lock for load holding.
