Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700S-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 700mm 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 SAUF50X700S-08B
The SAUF50X700S-08B is a double-acting profile-type cylinder featuring an integrated 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 50mm bore uses a 1/4" cylinder port, a M16x1.5 rod thread, and includes a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, it delivers 982N push at 0.5 MPa. The DC24V terminal coil offers IP65 protection and 3.0W consumption, while the valve provides 16 mm2 flow (Cv 0.89) up to 5 cycles/sec. For sizing, the safe working load is roughly 589N, allowing a vertical lift of about 50kg 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X700S-08B Is Used
Decentralized Divert Gate
Uses the built-in 4M210-08 valve to actuate a sorting flap directly on the conveyor frame, cutting tubing runs back to a central manifold.
Long-Reach Pusher Arm
Drives a 700mm stroke pusher to transfer palletized goods between zones without needing a separate remote valve bank.
Independent Clamp Station
Provides single-signal clamping on a machining cell, using the integrated magnet for position feedback via CMSG switches.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700S-08B the Right Choice?
When sizing, compare neighbouring bores: a 40mm bore yields 628N push while a 63mm bore yields 1559N at 0.5 MPa. This 50mm unit provides 982N push and 825N pull. Confirm the DC24V terminal entry and PT threads meet your control specs. The cylinder body rates to 1.0 MPa, but you must size force within the built-in valve's 0.15-0.8 MPa range. The valve routes air and is not a load lock; if power or air is lost, the piston drifts. For a held load, add an external rod lock or pilot-operated check valve. With a 700mm stroke, add 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 SAUF50X700S-08B FAQ
It pushes 982N and pulls 825N at 0.5 MPa. The built-in valve is a 4M210-08 5/2 solenoid with 1/4" port, Cv 0.89, and 5 cycles/sec max. The DC24V coil runs at 3.0W with IP65 protection. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate in the 0.15-0.8 MPa valve window.
The default action retracts the rod when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design means one coil signal drives the cylinder without a remote valve.
