Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X100-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X100-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 100mm 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 SAUF50X100-08B
The AirTAC SAUF50X100-08B is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. This 50mm bore pushes 982N and pulls 825N at 0.5MPa, operating within the valve's 0.15-0.8MPa range.
The integrated valve provides 16mm2 flow (Cv 0.89) and handles up to 5 cycles per second. It features terminal entry, PT threads, and uses Ø8xØ5 PU tubing. For sizing, the safe working load is roughly 589N (60% of the 0.5MPa push force), translating to a vertical lift capacity of about 50kg with a 2:1 margin. Note this SKU lacks the S suffix for 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 SAUF50X100-08B Is Used
Decentralized Clamping
Ideal for clamping stations on large machines where running individual lines to a central manifold is impractical, switching directly from one local DC24V signal.
Inline Divert Gate
Operates a short-stroke diverting flap on a packaging line, saving manifold space while delivering 982N push force at 0.5MPa to deflect products.
Localized Stopper Arm
Serves as an independent pallet stopper in a conveyor zone, using the built-in 4M210-08 valve to eliminate extra tubing runs back to a main control panel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X100-08B the Right Choice?
Size this 50mm bore against its neighbours: a 40mm bore yields 628N push while a 63mm bore provides 1559N at 0.5MPa. The 982N push force here fits mid-range tasks. Confirm the DC24V coil and terminal entry match your control scheme. The cylinder body rates to 1.0MPa, but you must size force within the 4M210 valve's 0.15-0.8MPa operating window. The rod retracts when energised by default; reposition the valve to extend on signal. The integrated valve routes air but does not function as a load lock—add an external rod lock or pilot-operated check valve to hold loads safely. For this 100mm stroke, side-load is minimal, but for strokes over 300mm, add a guide 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 SAUF50X100-08B FAQ
It delivers 982N push and 825N pull at 0.5MPa, using a built-in 4M210-08 valve (1/4" port, Cv 0.89, 16mm2 flow) on a 50mm bore with a 1/4" cylinder port. The coil is DC24V with terminal entry. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
Yes, the default action retracts the rod when the coil is energised, but you can reposition the valve to extend on signal. The valve only routes air; it is not a load lock. The piston will drift on air loss, so install an external rod lock or pilot-operated check valve if you need to maintain position.
