Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100S-08A is a genuine double-acting profile-type cylinder with a Ø40mm 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 SAUF40X100S-08A
The AirTAC SAUF40X100S-08A is a double-acting profile cylinder with a built-in 4M210-08 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 cylinder of the same bore. It features a 1/4" cylinder port, an M12x1.25 rod thread, and a 21mm adjustable cushion.
Operating within the valve's 0.15-0.8 MPa window, this 40mm bore delivers 628N push and 528N pull at 0.5 MPa. The AC220V terminal-entry coil offers IP65 protection and responds in 0.05s or less. The integrated valve provides 16mm2 flow (Cv 0.89) at up to 5 cycles per second. For sizing, the safe working load is roughly 377N (about 60% of the 0.5MPa push force), translating to a vertical lift capacity of approximately 32kg with a 2:1 safety margin. The S suffix indicates a piston magnet for CMSG/DMSG/EMSG sensors.

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 SAUF40X100S-08A Is Used
Decentralized Clamping Station
Ideal for a machining cell where each clamping actuator switches itself via one coil signal, eliminating a central manifold and long tube runs.
Independent Diverter Gate
Perfect for a conveyor diverter that needs to cycle independently at up to 5 cycles per second without dedicating a remote valve island slot.
Compact Sorter Pusher
Fits space-constrained sorting lines where the short profile body and integrated 4M210 valve minimize the overall machine footprint.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100S-08A the Right Choice?
Size force within the 0.15-0.8 MPa valve operating range, not the 1.0 MPa cylinder body rating. At 0.5 MPa this 40mm bore pushes 628N; if you need less force, drop to the 32mm bore (402N push), or step up to the 50mm bore (982N push) for more thrust. Confirm the AC220V terminal entry matches your supply. The rod retracts when the coil is energised; you can reconfigure it to extend-when-energised by repositioning the valve. The built-in valve routes air but is not a lock—a plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve to hold a load. For this 100mm stroke, side-load is minimal, but for strokes 300mm or longer, guide the load to prevent rod bending.
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 SAUF40X100S-08A FAQ
It pushes 628N and pulls 528N at 0.5 MPa, reaching 1005N at 0.8 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec max). The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window. The coil is AC220V with terminal entry.
Yes, the default action retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. The valve only routes air; it does not lock the piston. If air is lost, the load drifts, so install an external rod lock or pilot-operated check valve for load holding.
