Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X600-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X600-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 600mm 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 SAUF50X600-08A
The SAUF50X600-08A 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. This 50mm bore unit pushes 982N and pulls 825N at 0.5MPa, with a 1/4" cylinder port and an M16x1.5 rod thread.
The integrated valve delivers a 1/4" port, 16mm2 flow (Cv 0.89), and switches up to 5 cycles per second. It operates on an AC220V terminal entry coil (IP65, class B, under 0.05s response). The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa window. Based on the 982N push at 0.5MPa, the safe working load is roughly 589N, and it can vertically lift about 50kg with a 2:1 margin. This SKU 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 SAUF50X600-08A Is Used
Divert Gate Actuation
Decentralized sorting line diverters where one coil signal per actuator eliminates long tube runs back to a central manifold.
Packaging Pusher
Independent product push-off stations on a packaging conveyor, saving manifold slots and simplifying installation.
Machine Guard Flap
Remote access doors on large machinery where routing a local 1/4" supply is faster than plumbing a remote valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X600-08A the Right Choice?
When sizing, compare both ways: the neighboring 63mm bore offers 1559N push at 0.5MPa, while the 40mm bore offers 628N. This 50mm bore provides 982N push and 825N pull at 0.5MPa. Confirm your coil is AC220V with terminal entry before ordering. The default action retracts the rod when energized, but you can reposition the valve to extend on energization. Always operate within the 0.15-0.8MPa valve range, never the 1.0MPa cylinder body limit. 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. For this 600mm stroke, use external guides to prevent rod bending and side-load damage.
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 SAUF50X600-08A FAQ
It pushes 982N and pulls 825N at 0.5MPa. The built-in valve is a 4M210-08 (Cv 0.89, 5 cycles/sec max) with a 1/4" port. The AC220V terminal coil is IP65. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window.
By default, the rod retracts when the coil is energized. You can reconfigure it to extend when energized simply by repositioning the built-in valve. Because the valve only routes air, it is not a load lock, so you need an external rod lock or pilot-operated check valve to hold a load without air.
