Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700-08A 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 SAUF50X700-08A
The SAUF50X700-08A is an extruded aluminum profile-type double-acting cylinder, shorter than an ISO 15552 unit of the same bore. It integrates an AirTAC 4M210-08 5/2 solenoid valve directly on the cap. One coil signal drives the cylinder, eliminating remote plumbing and saving a manifold slot. The bore dictates a 1/4-inch cylinder port with an M16x1.5 rod thread.
Operate within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it pushes 982 N and pulls 825 N. The safe working load is roughly 589 N, allowing a vertical lift of about 50 kg with a 2:1 margin. The 1/4-inch valve port gives 16 mm2 flow (Cv 0.89) at up to 5 cycles per second. This AC220V terminal-entry coil is IP65 rated. Since this SKU lacks the S suffix, it cannot take 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 SAUF50X700-08A Is Used
Decentralized Conveyor Divert
Mounts directly at a remote divert station on a long conveyor line. The integrated 4M210 valve switches the 700 mm stroke locally, saving tubing runs back to a central manifold.
Remote Pallet Stop Gate
Ideal for a standalone pallet stop gate in a large warehouse. One AC220V signal drives the 50 mm bore, eliminating the need for a dedicated remote valve island.
Machine Guard Door Actuator
Drives a heavy machine guard door. The compact profile cylinder with built-in 5/2 valve frees up manifold space while providing 982 N push force at 0.5 MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700-08A the Right Choice?
Size by checking both neighboring bores: the 40 mm bore pushes 628 N while the 63 mm bore pushes 1559 N at 0.5 MPa. This 50 mm bore provides 982 N push and 825 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve operating range, never the 1.0 MPa cylinder body rating. Confirm your coil is AC220V with terminal entry. The rod retracts when the coil is energized; reposition the valve to reverse this to extend-when-energized. Because the 700 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load damage. The built-in valve only routes air and is not a lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve for load holding.
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 SAUF50X700-08A FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-08 (5/2 solenoid) with a 1/4-inch port, 16 mm2 flow (Cv 0.89), and a 5 cycle/s limit. The coil is AC220V with terminal entry. You must size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energized. You can reconfigure it to extend-when-energized by physically repositioning the built-in valve on the cap. This decentralized design means one coil signal drives the cylinder directly, saving a remote valve and manifold slot.
