Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 50mm 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 SAUF50X50-06B
The AirTAC SAUF50X50-06B is a double-acting profile cylinder with a built-in 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 makes it shorter than an ISO 15552 unit of the same bore. This 50mm bore provides 982N push and 825N pull at 0.5MPa, operating within the 0.15-0.8MPa valve window.
The integrated valve is a 4M210-06 with a 1/8" port, 14mm2 flow (Cv 0.78), and a 5 cycle/s limit. The DC24V coil uses 3.0W, features IP65 protection, and responds in 0.05s or less. The cylinder bore has a 1/4" port and uses PU tube Ø8xØ5. For sizing, the safe working load is roughly 589N (60% of the 0.5MPa push force), translating to a 50kg vertical lift capacity 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 SAUF50X50-06B Is Used
Diverter Gate Actuation
Drives a decentralized sorting flap directly at the conveyor lane without running long tubing back to a central manifold.
Independent Clamping Station
Provides single-signal part clamping on an automated machining cell, freeing up manifold slots for other actuators.
Component Insertion Jig
Executes a dedicated press-fit motion at a standalone workstation using its 982N push force at 0.5MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-06B the Right Choice?
When sizing, compare neighbouring bores: a 40mm bore yields 628N push while a 63mm bore yields 1559N at 0.5MPa. This 50mm model provides 982N push and 825N pull at 0.5MPa. Confirm the DC24V terminal entry and PT threads suit your supply. The cylinder body rates to 1.0MPa, but you must size force within the built-in valve's 0.15-0.8MPa working range. The rod retracts when the coil is energised; reposition the valve to reverse this to extend-when-energised. Because this SKU lacks the -S magnet suffix, it cannot accept a magnetic switch. The valve only routes air, so for load holding on air loss add an external rod lock or pilot-operated check valve. For this 50mm stroke side-load is minimal, but any stroke over 300mm requires guide rails 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 SAUF50X50-06B FAQ
It delivers 982N push and 825N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max) with a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa pressure window.
The valve routes air but does not lock the piston, so the load drifts on air loss; add an external rod lock for holding. By default the rod retracts when energised, but you can reposition the valve on the cap to make it extend-when-energised.
