The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X500S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 500mm 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.
The SAUF40X500S-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 extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. This 40mm bore uses a 1/4" cylinder port and a 1/8" valve port.
The integrated valve flows 14 mm2 (Cv 0.78) at up to 5 cycles/sec. It runs on DC24V with terminal entry and includes a piston magnet for CMSG/DMSG/EMSG switches. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa window. At 0.5 MPa it pushes 628 N and pulls 528 N. The safe working load is about 377 N, allowing a vertical lift of roughly 32 kg 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.

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.
Drive a sorting diverter directly at the lane. One coil signal actuates the gate without tubing back to a central manifold.
Mount this cylinder on a distant conveyor section. The built-in valve eliminates long air lines and response delays.
Actuate a clamping fixture on a large machine bed. The integrated valve saves manifold space and simplifies wiring.
When sizing, compare both directions: this 40mm bore pushes 628 N and pulls 528 N at 0.5 MPa. If you need less force, the 32mm bore pushes 402 N; for more power, the 50mm bore pushes 982 N. Confirm your coil is DC24V with terminal entry before ordering. The rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. Always operate within the 0.15-0.8 MPa valve limit, never the 1.0 MPa cylinder body rating. Because air only routes through the valve, add an external rod lock or pilot-operated check valve to hold a load. For this 500mm stroke, use external guides to prevent rod bending and side loads.
Quick checklist
It pushes 628 N and pulls 528 N at 0.5 MPa using a 4M210-06 valve (Cv 0.78, 1/8" port). The DC24V coil operates at up to 5 cycles/sec. Size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod when energised, but you can reposition the built-in valve to extend-when-energised. This keeps the one-signal switching benefit without needing a remote valve.
