Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 50mm 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 SAUF32X50-08A
The SAUF32X50-08A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This 32mm bore pushes 402N at 0.5MPa within the 0.15-0.8MPa valve operating window.
The integrated valve offers 1/4" porting with 16mm2 flow (Cv 0.89) and cycles up to 5 times per second. It uses an AC220V terminal entry coil rated IP65. The cylinder port is 1/8". For sizing, expect a safe working load around 241N or a 20kg vertical lift with a 2:1 margin. Note this SKU lacks the S suffix for a magnet, so it cannot accept a sensor.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAUF32X50-08A Is Used
Compact Part Ejection
Mounts directly at the ejector station on a molding line. The built-in valve provides rapid 5 cycle/sec actuation without running long tubing back to a central manifold.
Decentralized Clamping
Ideal for independent clamping fixtures on a large machining bed. One AC220V signal controls this 32mm actuator locally, freeing up manifold slots for other functions.
Inline Diverting Gate
Powers a short-stroke diverting flap on a packaging conveyor. The 1/4" valve port delivers fast response, and the compact profile fits neatly within the conveyor frame.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50-08A the Right Choice?
When sizing, compare this 32mm bore (402N push at 0.5MPa) against the 40mm bore (628N) to ensure adequate force. Keep operating pressure between 0.15 and 0.8MPa; the cylinder body rates to 1.0MPa but the built-in valve limits the assembly. The coil is AC220V with terminal entry. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. The valve only routes air, so for load holding on air loss add an external rod lock or pilot-operated check valve. At 50mm stroke, side-load guiding is minimal, but always guide loads over 300mm.
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 SAUF32X50-08A FAQ
It delivers 402N push and 345N pull at 0.5MPa using a built-in 4M210-08 valve (1/4" port, Cv 0.89, 5 cycles/sec). The assembly runs on AC220V and must operate within the 0.15-0.8MPa valve window, even though the cylinder body rates to 1.0MPa.
This specific SKU lacks the S suffix, so it cannot accept a magnetic switch. Additionally, the built-in valve routes air but does not lock the piston; if air is lost, the load drifts. Use an external rod lock or pilot-operated check valve for holding.
