The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250S-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 250mm 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.
The SAUF100X250S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 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 is shorter than an ISO 15552 unit of the same bore. This 100mm bore version has a 1/2" cylinder port, an M20x1.5 rod thread, and a 29mm adjustable cushion.
Operating in the 0.15-0.8 MPa valve window, it delivers 3927N push force at 0.5MPa. The safe working load is roughly 2356N (60% of the 0.5MPa figure), allowing a 200kg vertical lift with a 2:1 margin. The integrated valve flows 25mm2 (Cv 1.4) at 1/4", cycling up to 4 times per second. This -S model includes a piston magnet for CMSG/DMSG/EMSG switches, uses a DC24V terminal coil, and pairs with Ø10xØ6.5 PU tube.

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.
Clamps heavy workpieces directly at the press station. The integrated valve removes long tube runs back to a central manifold, improving cycle response.
Actuates a heavy divert gate on a high-speed packaging line. One DC24V signal drives the 100mm bore, simplifying control wiring and saving manifold space.
Lifts pallets within a localized cell. The built-in 4M310-08 valve handles the 3927N push force at 0.5MPa without needing a remote valve island.
Size this 100mm bore against the neighbouring 80mm option: at 0.5MPa the 80mm yields 2513N push while this 100mm reaches 3927N. Confirm the DC24V terminal entry and 1/4" valve port suit your supply. The cylinder body rates to 1.0MPa but you must size force within the built-in valve's 0.15-0.8MPa range. Default action retracts the rod when energised; reposition the valve to extend on signal. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold a load. For this 250mm stroke, guide the mechanism to manage side loads.
Quick checklist
It pushes 3927N and pulls 3681N at 0.5MPa, reaching 6282N push at 0.8MPa. The built-in valve is a 4M310-08 5/2 solenoid with 1/4" port, Cv 1.4, and a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate in the 0.15-0.8MPa valve range.
Yes. The default action retracts the rod when energised, but you can reposition the built-in valve to make the rod extend on signal. This allows decentralized one-valve-per-actuator control without altering your remote plumbing.
