The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X225S-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 225mm 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 SAIF40X225S-06B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0W, it delivers a 628N push force at 0.5MPa. While the bare cylinder rates to 1.0MPa, the practical operating range for this valved unit is 0.15-0.8MPa. The integrated manifold uses an O8xO5 PU tube, eliminating separate remote plumbing.
By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This self-contained design requires only one coil signal to switch, saving panel space. The -S magnet supports CMSE reed and DMSE electronic sensors for precise positioning feedback.

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 for a remote valve island on large machines by switching the cylinder directly from a single DC24V signal.
The integrated manifold block saves valuable panel and floor space by removing extensive tubing runs to a central control cabinet.
Ideal for upgrading older equipment where adding new pneumatic plumbing is difficult, relying on simple electrical wiring instead.
Choose this 40mm bore when you need 628N of push force at 0.5MPa, stepping up from the 32mm bore (402N) for higher load capacity, or stepping down from the 50mm bore (982N) to save space. A self-valved SAIF is ideal for decentralized stations where running separate valve tubing is costly. It includes a carbon steel rod and PT tapered threads.
For replacement, match the 40mm bore, 225mm stroke, 1/8" cylinder port, 06 (1/8") valve port, DC24V voltage, terminal entry, and -S magnet. Since the 225mm stroke is over 300mm, ensure adequate side-load guidance to prevent rod binding. Remember, the 5/2 valve routes air but does not lock the load; for position holding, consider a SAIL lock cylinder.
Quick checklist
The 40mm bore provides 628N push and 528N pull force at 0.5MPa. The built-in 4M210-06 valve has a 14.0mm2 orifice (Cv 0.78) and a max frequency of 5 cycles/sec.
The factory default setting retracts the rod when the coil is energised. Because it uses a 5/2 pilot valve, it can be easily reconfigured to extend-when-energised by repositioning the valve, requiring no separate remote valve.
