Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000S-08B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 1000mm 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 SAUF40X1000S-08B
The SAUF40X1000S-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 cylinder of the same bore. The bore dictates a 1/4" cylinder port, while the valve features a 1/4" port with a 16 mm2 flow (Cv 0.89) and a 5 cycle/s limit.
Operating on DC24V with terminal entry, the coil offers IP65 protection and a 0.05 s response. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa window. At 0.5 MPa it delivers 628 N push and 528 N pull. A practical computed insight: the safe working load is roughly 377 N, and it can vertically lift about 32 kg 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 (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 SAUF40X1000S-08B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert station to push packages, needing only one electrical signal and no long tubing runs back to a central manifold.
Remote Machine Gating
Ideal for opening safety gates on large machinery where routing a remote valve would be cumbersome, saving plumbing time and manifold slots.
Long-Stroke Material Stop
Acts as a 1000 mm material stop in a high-bay warehouse, using its integrated 4M210-08 valve to switch itself locally without a separate valve island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000S-08B the Right Choice?
When sizing, compare both directions against neighboring bores: this 40 mm bore gives 628 N push and 528 N pull at 0.5 MPa, whereas a 32 mm bore yields 402 N push and a 50 mm bore yields 982 N push. Always confirm your coil voltage (DC24V) and entry (terminal) before ordering. The default action retracts the rod when energized, but you can reconfigure it to extend-when-energized by repositioning the valve. Size your force strictly within the 0.15-0.8 MPa valve operating window, never the 1.0 MPa cylinder body rating. The built-in valve only routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. Because the 1000 mm stroke exceeds 300 mm, use external guides to prevent rod bending and side-load damage.
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 SAUF40X1000S-08B FAQ
It pushes 628 N and pulls 528 N at 0.5 MPa. The built-in valve is a 4M210-08 (5/2 solenoid) with a 1/4" port, 16 mm2 flow (Cv 0.89), and a 5 cycle/s limit. The coil is DC24V with terminal entry. You must size force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
By default, the rod retracts when the coil is energized. You can reconfigure it to extend-when-energized simply by repositioning the valve on the cap. This self-switching design means one coil signal drives the cylinder, eliminating the need for a separate remote valve and saving a manifold slot.
