Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 160mm 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 SAUF50X160-08A
The SAUF50X160-08A is a double-acting profile cylinder with a built-in 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 cylinder of the same bore, and the 1/4" cylinder port handles air efficiently.
Operating strictly within the valve's 0.15-0.8 MPa window, this bore pushes 982 N and pulls 825 N at 0.5 MPa. The integrated valve delivers a 16 mm2 flow (Cv 0.89) at up to 5 cycles per second. For sizing, the safe working load is roughly 589 N, and it can vertically lift about 50 kg with a 2:1 margin. This terminal-entry AC220V SKU lacks a magnet, 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 SAUF50X160-08A Is Used
Inline Diverter Gate
Switches a sorting flap directly on the conveyor frame using one AC220V signal, skipping a central manifold and cutting tubing runs.
Decentralized Clamp Station
Provides 982 N of clamping force at a standalone machining cell, actuating instantly without dedicating a valve island slot.
Carton Flap Folder
Folds box flaps at up to 5 cycles per second, using the compact profile to fit tightly inside high-speed packing machinery.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160-08A the Right Choice?
When sizing, compare this 50 mm bore (982 N push at 0.5 MPa) against the 40 mm bore (628 N) and 63 mm bore (1559 N) to match your load. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Confirm the AC220V coil and terminal entry suit your control panel. The rod retracts when energised by default, but you can reposition the valve to extend on signal. Because this SKU lacks a magnet, it cannot take a sensor. The valve only routes air; it is not a lock, so add an external rod lock or pilot-operated check valve to hold a load. For this 160 mm stroke, side-load is minimal, but always guide the rod end to prevent 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 SAUF50X160-08A FAQ
It features a 50 mm bore, 160 mm stroke, and a built-in 4M210-08 valve with a 1/4" port, Cv 0.89, and 5 cycles/sec max. The AC220V terminal-entry coil runs on 0.15-0.8 MPa. It pushes 982 N and pulls 825 N at 0.5 MPa, reaching 1570 N at 0.8 MPa. The 1/4" cylinder port and M16x1.5 rod thread handle the air and mechanical loads.
No. The built-in 5/2 valve routes air but does not lock the piston. If air is lost, the load drifts. You must add an external rod lock or pilot-operated check valve for holding. Also, the default action retracts the rod when energised, but you can reposition the valve to extend on signal.
