Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 700mm stroke and a built-in 4M210-06 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-06A
The SAUF50X700S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 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. This 50mm bore unit has a 1/4" cylinder port, an M16x1.5 rod thread, and a 21mm adjustable cushion at each end.
The integrated 4M210-06 valve features a 1/8" port, 14mm2 flow (Cv 0.78), and runs at 5 cycles/sec. It operates on AC220V via terminal entry. Because the valve limits the assembly to a 0.15-0.8 MPa window, size forces within that range rather than the 1.0 MPa cylinder body rating. At 0.5 MPa it pushes 982N and pulls 825N. A computed buyer insight: safe working load is roughly 589N, and vertical lift is about 50kg 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 (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-06A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate to actuate on one AC220V signal, removing long tube runs back to a central manifold.
Independent Lift Station
Uses the built-in 4M210 valve to cycle a 50kg vertical lift at up to 5 cycles/sec without consuming a manifold slot.
Long-Stroke Component Pusher
Drives a 700mm push stroke with 982N force, relying on adjustable cushions to decelerate the load at stroke end.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700S-06A the Right Choice?
When sizing, compare this 50mm bore (982N push at 0.5 MPa) against the 40mm bore (628N) or 63mm bore (1559N) to match your load. Confirm the AC220V coil and terminal entry meet your control specs. The rod retracts by default when energised, but you can reconfigure it to extend by repositioning the valve. Always size pressure within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder rating. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load safely. For the 700mm stroke, 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 SAUF50X700S-06A FAQ
It delivers 982N push and 825N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) running on AC220V. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
No. The built-in valve only routes air; it is not a lock. The rod retracts when energised by default, but you can reposition the valve to extend on signal. For load holding on air loss, install an external rod lock or pilot-operated check valve.
