Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 300mm stroke and a built-in 4M310-08 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 SAUF100X300-08A
The AirTAC SAUF100X300-08A is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, 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 100mm bore features a 1/2" cylinder port, an M20x1.5 rod thread, and 29mm adjustable cushions.
It delivers 3927N push and 3681N pull at 0.5MPa. The integrated valve flows 25mm2 (Cv 1.4) at a 1/4" port, cycling up to 4 times per second. Because the valve routes air rather than locking it, add an external rod lock for hold. With a 60% safety factor, expect a 2356N safe working load, or a 200kg vertical lift. Note this SKU lacks the S suffix, so it cannot take 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAUF100X300-08A Is Used
Heavy Stamp Press
Decentralized actuation for a stamping press, using the built-in valve to cycle the 100mm bore directly without routing long tubing to a central manifold.
Pallet Diverter
Single-signal routing for a heavy pallet diverter arm, where the integrated 4M310-08 valve handles the 300mm stroke independently of remote valve banks.
Vertical Lift Gate
Driving a large lift gate in a warehouse, taking advantage of the 3927N push force at 0.5MPa while saving installation time with the cap-mounted valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X300-08A the Right Choice?
When sizing, compare neighbouring bores: the 80mm bore yields 2513N push at 0.5MPa, while this 100mm bore yields 3927N. Confirm your coil is AC220V with terminal entry. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Size force strictly within the 0.15-0.8MPa valve window, never the 1.0MPa cylinder body rating. For this 300mm stroke, fit external guides to prevent rod bending under side loads. The valve only routes air, so use a pilot-operated check valve for load holding.
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 SAUF100X300-08A FAQ
It pushes 3927N and pulls 3681N at 0.5MPa, reaching 6282N push at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25mm2 flow) running on an AC220V terminal-entry coil. You must size force within the valve's 0.15-0.8MPa operating window, not the 1.0MPa cylinder body rating.
Yes. The default factory setting retracts the rod when the coil receives power, but you can reposition the built-in valve to make the rod extend on signal. This allows flexible decentralized control without altering your wiring, though the valve only routes air and does not lock the load.
