Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X100-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X100-08A is a genuine double-acting profile-type cylinder with a Ø32mm 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 SAUF32X100-08A
The AirTAC SAUF32X100-08A is a compact double-acting profile cylinder with a built-in 4M210-08 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 makes it shorter than an ISO 15552 unit of the same bore. This 32mm bore generates 402N push and 345N pull at 0.5MPa, with a 1/8" cylinder port and an M10x1.25 rod thread.
The integrated valve offers 1/4" porting, 16mm2 flow (Cv 0.89), and runs up to 5 cycles/sec. The AC220V terminal-entry coil is IP65 rated with a 0.05s response. Size force within the 0.15-0.8MPa valve window, even though the cylinder body rates to 1.0MPa. Based on the 0.5MPa push force, the safe working load is roughly 241N, translating to a vertical lift capacity of about 20kg with a 2:1 margin. This SKU lacks a magnet and 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 SAUF32X100-08A Is Used
Modular Assembly Stations
Decentralized clamping across large custom fixtures. The built-in 4M210 valve lets each actuator switch independently from one coil signal, cutting tubing runs.
Conveyor Diverters
Ideal for localized sorting gates where installing a central valve manifold is impractical. The compact 32mm profile fits tight transfer spaces.
Small Part Ejection
High-speed ejection of parts from presses. The valve handles up to 5 cycles/sec, providing rapid actuation without remote valve delay.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X100-08A the Right Choice?
When sizing, compare this 32mm bore (402N push at 0.5MPa) against the neighbouring 40mm bore (628N push) to ensure adequate force. The assembled unit must operate within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating. Confirm the AC220V terminal entry matches your supply. The rod retracts by default when energised but can be reconfigured to extend by repositioning the valve. This model has no magnet, so it cannot accept position sensors. The valve routes air and is not a lock; if you need to hold a load against air loss or pressure drops, add an external rod lock or pilot-operated check valve. 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 SAUF32X100-08A FAQ
It delivers 402N push and 345N pull at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5/2 solenoid) running on an AC220V terminal-entry coil. 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 energised, but you can reposition the valve to make it extend-when-energised. The valve only routes air; it is not a load lock. The piston will drift on air loss, so fit an external rod lock or pilot-operated check valve for load holding.
