Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 300mm 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 SAUF50X300-06B
The SAUF50X300-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot in decentralized installations. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. This SKU uses a terminal entry, PT threads, and Ø8xØ5 PU tubing.
It delivers 982 N push and 825 N pull at 0.5 MPa. The safe working load is roughly 589 N (60% of the 0.5 MPa push), and it can vertically lift about 50 kg with a 2:1 margin. The 1/8" valve port yields a 14 mm2 flow (Cv 0.78) and cycles up to 5 times per second. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa window. This version lacks a magnet (-S), so it cannot accept a magnetic switch.

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 SAUF50X300-06B Is Used
Diverter Gate Actuation
Decentralized sorting line diverter where the integrated valve removes the need to run long control lines back to a central manifold.
Packaging Machine Pusher
Single-signal product rejection pusher that leverages the compact profile and 5 cycles/s valve speed for high-throughput boxing.
Independent Clamping Station
Stand-alone machining clamp using one coil signal per actuator, saving manifold slots and simplifying pneumatic plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300-06B the Right Choice?
When sizing, compare this 50 mm bore (982 N push at 0.5 MPa) against the neighboring 40 mm (628 N) and 63 mm (1559 N) options. Verify the DC24V terminal coil and 1/4" cylinder port meet your supply. The assembled unit operates strictly at 0.15-0.8 MPa, not the 1.0 MPa cylinder body rating. By default the rod retracts when energized; you can reconfigure it to extend by repositioning the valve. Because the 300 mm stroke invites rod bending, use an external guide to manage side loads. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold a load safely.
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 SAUF50X300-06B FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-06 (5/2 solenoid) with a 1/8" port, 14 mm2 flow (Cv 0.78), and a 5 cycles/s limit. The coil is DC24V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly within the 0.15-0.8 MPa valve window.
By default the rod retracts when the coil is energized, but you can reconfigure it to extend by repositioning the valve. The 5/2 valve only routes air; it is not a lock. The piston will drift on air loss, so you must add an external rod lock or pilot-operated check valve for load holding.
