Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 600mm stroke and a built-in 4M210-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08B
The AirTAC SAIF40X600-08B is a double-acting ISO 15552 profile cylinder paired with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89. Driven by a DC24V terminal coil consuming 3.0 W, it activates in 0.05 s or less with IP65 protection. Because the cylinder body rates to 1.0 MPa but the integrated 4M valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. It delivers 628N of push force and 528N of pull force at 0.5 MPa.
By integrating the valve directly onto the manifold block via O8 x O5 PU tubing, this unit eliminates remote plumbing and saves panel space for decentralized machine stations. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The cylinder port is PT1/4, while the valve port code is 08 (1/4), and standard carbon steel rod material is used.

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.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
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).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08B Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve bank, allowing independent cylinder control directly at the station using the DC24V terminal signal.
Long-Stroke Material Handling
Ideal for 600mm push operations where a 40mm bore provides sufficient 628N force at 0.5 MPa without the bulk of a larger cylinder.
Space-Constrained Machinery
The built-in 4M210-08 valve and manifold block save valuable panel space and reduce tubing runs in tight machine layouts.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08B the Right Choice?
Choose this 40mm bore if you need more force than the 32mm version (402N push at 0.5 MPa) but want a smaller footprint than the 50mm bore (982N push at 0.5 MPa). A self-valved SAIF beats a separate cylinder and remote valve when you want to minimize wiring and tubing across decentralized stations. For this DC24V terminal entry model, ensure your control system matches the 3.0 W coil and PT threaded ports. Since the 4M210 valve is a 5/2 pilot-held design, it will not hold the load without live pressure; use a SAIL lock or BSAI clamp-lock if position holding is required.
For this 600mm stroke, which exceeds 300mm, you must account for side loads and use an external guide to prevent rod damage. To replace this unit, match the 40mm bore, 600mm stroke, 08 valve port, DC24V voltage, terminal entry, PT thread, and standard carbon steel rod. A magnet for CMSE or DMSE sensors is not included on this non-S configuration.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF40X600-08B FAQ
At 0.5 MPa, the 40mm bore provides 628N of push force and 528N of pull force. The maximum push force is 1130N at 0.9 MPa, though the practical operating pressure is capped at 0.8 MPa by the built-in valve.
Yes. The factory setting retracts the rod when the DC24V coil is energised, but you can reposition the 4M210-08 5/2 valve on the manifold to extend-when-energised. The valve holds its position by pilot pressure, not a spring.
