The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X300-06B 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 SAIF40X300-06B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering a 628N push force at 0.5 MPa. Bundling a DC24V terminal-entry coil and a Cv 0.78 valve directly on the manifold block eliminates remote plumbing. The unit operates effectively between 0.15-0.8 MPa, as the integrated valve governs the pressure range below the bare cylinder's 1.0 MPa rating.
Driven by a single electrical signal, this self-switching actuator is ideal for decentralized machine stations. The manifold links the valve to the cylinder via an O8xO5 PU tube, and the factory setting retracts the rod when the coil energizes. You can reposition the valve to extend-when-energised if your sequence requires it. The 5/2 spool holds its last position via internal pilot pressure, not a mechanical spring.

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).
Eliminates the need to run long air tubes back to a central valve island on large assembly lines, saving panel space and simplifying wiring.
Provides self-contained actuation for mid-force clamping fixtures where installing a separate remote valve would congest the work area.
Ideal for upgrading older machines by adding localized pneumatic control via a single DC24V electrical signal without extensive plumbing.
Choose this 40mm bore when a 32mm cylinder lacks thrust (32mm yields 402N push at 0.5 MPa) or a 50mm unit is oversized (50mm yields 982N). The 300mm stroke falls within the 1200mm standard limit, but at this length you should use a guide rail to prevent rod side-loading and premature seal wear. The integrated 4M210-06 valve features a 1/8" port and a 14.0mm2 orifice, making it highly compact.
Select this DC24V terminal configuration for safe, low-voltage control panels. Because the 5/2 valve routes air continuously, it will not hold the load mechanically if pressure drops; for true locking requirements, consider an SAIL lock cylinder. To replace this unit, match the 40mm bore, 300mm stroke, 1/8" cylinder port, PT thread, carbon steel rod, and terminal entry without a magnet.
Quick checklist
At 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. The integrated 4M210-06 valve has an effective area of 14.0mm2 (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
No, the 4M210-06 5/2 valve is built directly into the manifold block. It operates on a DC24V terminal coil drawing 3.0W. By factory default, energizing the coil retracts the rod, but you can reposition the valve to extend-when-energised.
