Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 200mm 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 SAUF40X200S-06B
The SAUF40X200S-06B 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, eliminating remote plumbing and saving a manifold slot. The 40mm bore delivers 628N push and 528N pull at 0.5MPa, operating safely within the 0.15-0.8MPa valve window. The cylinder body rates to 1.0MPa, but the integrated valve limits the assembled unit to 0.8MPa. The 1/4" cylinder port and M12x1.25 rod end handle flow efficiently.
This unit features a 4M210-06 valve with a 1/8" port, 14mm2 flow (Cv 0.78), and 5 cycles/sec. It uses a DC24V terminal entry coil rated IP65. The S suffix adds a piston magnet for CMSG/DMSG/EMSG switches. For sizing, the safe working load is roughly 377N (60% of the 0.5MPa push), allowing a 32kg vertical lift with a 2:1 margin.

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 SAUF40X200S-06B Is Used
Diverter Gate Actuation
Uses one coil signal to drive the diverter directly at the conveyor, cutting tubing runs to a central manifold.
Decentralized Clamping Station
Clamps parts independently on a large machine cell without consuming a slot on the main valve island.
Independent Pusher Head
Pushes cartons on a packaging line with a self-contained 4M210 valve, simplifying installation and maintenance.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X200S-06B the Right Choice?
Size by checking both neighboring bores: the 32mm bore yields 402N push at 0.5MPa, while the 50mm bore yields 982N. This 40mm bore provides 628N push, making it ideal for medium loads. Confirm the DC24V terminal entry and 1/8" valve port meet your electrical and flow needs. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8MPa valve range, never the 1.0MPa cylinder body rating. The integrated valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 200mm stroke, ensure proper guidance to prevent 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 SAUF40X200S-06B FAQ
It delivers 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) with a DC24V terminal 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 energized. You can reconfigure it to extend when energized simply by repositioning the built-in valve. This self-switching design removes the need for a remote valve, saving tubing and manifold space.
