Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X300-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X300-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 300mm stroke and a built-in 4M210-06 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 SAUF40X300-06B
The AirTAC SAUF40X300-06B is a double-acting profile cylinder with a built-in 4M210 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 makes it shorter than an ISO 15552 unit of the same bore. This 40mm bore delivers 628N push and 528N pull at 0.5MPa, with a 1/4" cylinder port and an M12x1.25 rod thread.
Size force within the 0.15-0.8MPa valve window, as the integrated valve restricts the assembly below the 1.0MPa cylinder body rating. The 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles 5 cycles/sec. A computed buyer insight: safe working load is roughly 377N (60% of the 628N push), yielding a 32kg vertical lift capacity with a 2:1 margin. This DC24V terminal-entry coil is IP65 rated. Since this SKU lacks the -S magnet suffix, 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAUF40X300-06B Is Used
Decentralized Conveyor Diverter
Mounts directly at the diverter station on a long conveyor line. The integrated valve eliminates long tube runs back to a central manifold, improving cycle response.
Independent Pack Push-Off
Ideal for a standalone push-off mechanism in a packing cell. One DC24V signal actuates the 300mm stroke without occupying a slot on the main valve island.
Multi-Station Assembly Jig
Perfect for jigs requiring individual actuator control. The compact profile fits tight machine frames while the 5/2 valve handles local routing without extra plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X300-06B the Right Choice?
When sizing, compare neighbouring bores: a 32mm bore yields 402N push at 0.5MPa, while a 50mm bore provides 982N. This 40mm bore gives 628N push and 528N pull at 0.5MPa. Confirm the DC24V terminal entry and PT threads meet your control specs. The cylinder body rates to 1.0MPa, but size strictly within the built-in valve's 0.15-0.8MPa operating range. The valve routes air but does not lock the piston; if power or air drops, the load drifts and the 21mm cushions only decelerate near stroke end. For a held load, add an external rod lock or pilot-operated check valve. With a 300mm stroke, use an external guide to prevent rod bending and side-load wear.
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 SAUF40X300-06B FAQ
It delivers 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-06 (5/2 solenoid) with a 1/8" port, Cv 0.78, and 5 cycles/sec max. The DC24V coil is IP65. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly at 0.15-0.8MPa.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised by repositioning the valve. The valve only routes air; it is not a lock. The load will drift on air loss, so add an external rod lock or pilot-operated check valve for holding.
