Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X600S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X600S-08B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 600mm 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 SAUF40X600S-08B
The SAUF40X600S-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 DC24V terminal-entry model includes a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, it delivers 628 N push and 528 N pull at 0.5 MPa. The 1/4" valve port flows 16 mm2 (Cv 0.89) at up to 5 cycles per second. Computed buyer insight: safe working load is roughly 377 N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of approximately 32 kg with a 2:1 margin. The cylinder body rates to 1.0 MPa, but the integrated valve limits the assembled unit to 0.8 MPa.

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 SAUF40X600S-08B Is Used
Inline Divert Gate
A single electrical signal actuates this diverter directly at the conveyor lane, avoiding long tube runs back to a central manifold.
Decentralized Case Pusher
Mounts independently on packaging lines to push cartons, saving manifold space and simplifying installation across large machines.
Independent Tool Station
Drives a remote machining or clamping station with one DC24V connection, removing the need for dedicated remote valve plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X600S-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. This 40 mm bore generates 628 N push and 528 N pull at 0.5 MPa. Confirm the DC24V coil, terminal entry, and PT thread meet your control specs. The cylinder body rates to 1.0 MPa, but the integrated valve restricts the assembled unit to 0.15-0.8 MPa. By default the rod retracts when the coil is energised; repositioning the valve changes this to extend-when-energised. The valve routes air and is not a load lock—add an external rod lock or pilot-operated check valve to hold a load. The 600 mm stroke exceeds 300 mm, so 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 SAUF40X600S-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, 5/2 solenoid) operating on DC24V. Although the cylinder body rates to 1.0 MPa, the integrated valve limits the assembled unit to a 0.15-0.8 MPa working range.
Yes. The default action retracts the rod when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve on the cap. Because the valve only routes air, use an external rod lock or pilot-operated check valve if you need to hold a load.
