Airtac SAIF Series Standard Cylinder with Valve SAIF100X400-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X400-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 400mm stroke and a built-in 4M310-08 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 SAIF100X400-08B
The AirTAC SAIF100X400-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific build pairs a 100mm bore and 400mm stroke with a DC24V terminal coil, drawing only 3.0 W. The built-in valve provides a Cv of 1.40 and a 25.0 mm2 effective area. Because the manifold routes air directly via PU tubing, you drive the cylinder from a single electrical signal without plumbing a remote valve. The cylinder body itself rates to 1.0 MPa, but the practical operating pressure for this valved assembly is 0.15-0.8 MPa.
Out of the factory, the piston rod retracts when the coil is energised; you can reconfigure it to extend-when-energised by repositioning the valve. At 0.5 MPa, this 100mm bore generates 3927 N of push force and 3681 N of pull force, making it suited for heavy actuation. The cylinder uses a carbon steel rod and PT tapered ports. The cylinder port is PT1/2, while the valve port is 1/4. It operates at speeds of 30-800 mm/s and includes adjustable air cushions at both ends to decelerate near stroke limits.

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 (Ø100mm)

| 0.7 MPa | 5498 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 SAIF100X400-08B Is Used
Decentralized Assembly Lines
Eliminates remote valve banks on large machines by switching directly from the DC24V terminal coil, reducing plumbing complexity.
Heavy Material Handling
Delivers up to 3927 N of push force at 0.5 MPa to move substantial loads across a 400mm stroke with end-cushioning.
Machine Retrofitting
Ideal for upgrading existing setups where running new pneumatic tubing back to a central panel is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X400-08B the Right Choice?
Choose this 100mm bore when smaller neighbours like the 63mm bore (1559 N push at 0.5 MPa) cannot move your load. The self-contained SAIF design is ideal for decentralized stations across large machines, saving panel space and cutting tubing runs. This specific SKU uses a DC24V terminal connection with a PT thread; verify your control system matches these parameters. For load-holding applications, note that the 5/2 valve routes air but does not lock the cylinder—consider the SAIL series for pneumatic locking needs.
Since the 400mm stroke is substantial, ensure proper guidance to prevent excessive side-loading on the rod seals. To replace this unit, match the 100mm bore, 400mm stroke, 1/4 valve port, DC24V voltage, terminal entry, PT thread, and standard carbon steel rod. The valve operates at a maximum frequency of 4 cycles per second.
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 SAIF100X400-08B FAQ
At 0.5 MPa, this 100mm bore cylinder provides 3927 N of push force and 3681 N of pull force. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40).
It uses a 5/2 solenoid valve that holds position by pilot pressure, not a spring. The factory setting retracts the rod when the DC24V coil is energised, but you can reposition the valve to extend-when-energised. No separate remote valve is needed.
