The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X300S-06B is a genuine double-acting ISO 15552 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.
The AirTAC SAIF40X300S-06B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering a Cv of 0.78 and a 14.0 mm2 effective area. Driven by a DC24V terminal coil consuming 3.0 W, it switches itself from a single electrical signal. While the bare cylinder rates to 1.0 MPa, the integrated valve limits the practical SAIF operating range to 0.15-0.8 MPa. This 40mm bore generates 628N of push force at 0.5 MPa, and the -S magnet enables position sensing with CMSE reed or DMSE solid-state switches.
By default, the piston rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve. The manifold connects to the cylinder via an O8 x O5 PU tube, and the valve port (1/8) differs from the cylinder port (1/8). This decentralized design eliminates remote plumbing, saving panel space and tubing across large machines.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF 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.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Ideal for distributing actuation across large machines where running individual valve tubing back to a central manifold is costly and complex.
The integrated valve manifold saves valuable panel and footprint space in compact packaging or handling equipment.
Simplifies upgrades on existing lines by driving the cylinder directly from a single DC24V coil signal without adding external valves.
Choose this 40mm bore when you need 628N push force at 0.5 MPa; step up to the 50mm bore for 982N if your load requires more thrust, or down to the 32mm for 402N in lighter applications. A self-valved SAIF beats a separate cylinder plus remote valve in space-tight machines by cutting wiring and plumbing. For stroke lengths of 300mm or more, always use a guide to prevent side-load damage to the piston rod. Note that the 5/2 valve routes air but does not hold the load without live pressure; for true locking, consider the SAIL series. Replacement match: 40mm bore, 300mm stroke, valve port 06, DC24V, terminal entry, PT thread, magnet included.
Quick checklist
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The built-in 4M210-06 valve provides a 14.0 mm2 effective area (Cv 0.78) and operates at a maximum frequency of 5 cycles per second.
No separate remote valve is needed. The integrated 5/2 solenoid valve switches the cylinder directly from a DC24V signal. By factory default, the rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
