Airtac SAIF Series Standard Cylinder with Valve SAIF40X450-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X450-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 450mm 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.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF40X450-06A
The AirTAC SAIF40X450-06A is a double-acting ISO 15552 profile cylinder paired with a built-in 4M210-06 5/2 solenoid valve. Driven by an AC220V terminal connection coil consuming 3.5 VA, it responds in 0.05s. The integrated valve manages a 14.0mm2 orifice (Cv 0.78) using internal pilot pressure, routing air through PU tubing (O8xO5) to the cylinder's PT1/8 ports. Because the valve body limits pressure, the practical working range is 0.15-0.8 MPa despite the cylinder body rating of 1.0 MPa.
At 0.5 MPa it delivers 628N push and 528N pull force, scaling to 1130N push at 0.9 MPa. Factory-set to retract the rod when energized, the valve can be repositioned to extend-when-energized if your logic requires it. By switching itself from one coil signal, this unit eliminates remote plumbing and saves panel space for decentralized machine stations.

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 SAIF40X450-06A Is Used
Decentralized Assembly Stations
Ideal for large machines with multiple stations, using the built-in 4M210 valve to actuate the 40mm bore locally without running long pneumatic lines back to a central manifold.
Long-Stroke Material Diverting
The 450mm stroke handles extended push-off or sorting tasks on conveyors, while the integrated AC220V valve ensures rapid 0.05s switching right at the action point.
Space-Constrained Machinery
Eliminates the need for a separate remote valve bank and mounting brackets, saving critical panel and floor space in compact automated equipment.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X450-06A the Right Choice?
Select this 40mm bore when 32mm (402N push at 0.5MPa) lacks power but 50mm (982N push) is oversized. The 450mm stroke suits long-travel handling, but because it exceeds 300mm you must account for rod side-loads and use external guide rails to prevent binding. Choose this self-valved SAIF over a separate cylinder and remote valve when decentralizing stations across a large machine, as it cuts tubing runs and wiring complexity.
This unit uses a 4M210-06 valve (PT1/8 valve port) with an AC220V terminal entry coil. The carbon steel rod and PT tapered threads are standard. It lacks a magnet for sensors; add -S for CMSE reed or DMSE electronic solid-state switches. Remember the 5/2 valve routes air but does not lock the load—use AirTAC SAIL for holding requirements.
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 SAIF40X450-06A FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa, reaching 1130N push at 0.9 MPa. The built-in 4M210-06 5/2 valve has a 14.0mm2 effective area (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
No, the 5/2 valve routes air but does not lock the load; use SAIL for holding. This model uses an AC220V terminal entry coil (3.5 VA, IP65). Factory-set to retract when energized, you can reposition the valve to extend-when-energized.
