Airtac SAIF Series Standard Cylinder with Valve SAIF63X400-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X400-10B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 400mm stroke and a built-in 4M310-10 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 SAIF63X400-10B
The AirTAC SAIF63X400-10B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This built-in valve provides a Cv of 1.68 and an effective orifice of 30 mm2, driving the 63mm bore to deliver 1559N of push force at 0.5 MPa. Supplied with a DC24V terminal electrical entry, the coil consumes 3.0 W, features IP65 protection, and activates in 0.05 seconds or less. Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa.
By switching itself from a single coil signal, this unit eliminates the need for a remote valve, reducing plumbing and panel space for decentralized machine stations. The manifold connects to the cylinder via O10 x O6.5 PU tubing, while the valve uses a 3/8 inch port (cylinder port is also 3/8 inch). Factory set to retract the piston rod when the coil is energised, the valve can be repositioned to extend-when-energised if your sequence requires it. The 5/2 valve holds its position pneumatically, so it is not a lock; for load-holding applications, consider the SAIL series.

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 (Ø63mm)

|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 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 SAIF63X400-10B Is Used
Decentralized Automation
Ideal for large machines with decentralized stations, eliminating long tubing runs back to a central panel by controlling the cylinder locally via the DC24V coil signal.
Space-Constrained Machinery
Perfect for tight envelopes where a separate valve manifold would not fit. The built-in 4M310 valve handles the 3/8 inch ported air flow directly on the cylinder body.
Retrofit & Upgrades
Simplifies machine upgrades where adding new pneumatic plumbing is costly. Route a single electrical wire to the terminal entry instead of piping a new air valve.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X400-10B the Right Choice?
Choose this 63mm bore when 50mm (982N push at 0.5 MPa) is too weak or 80mm (2513N push at 0.5 MPa) is oversized. A self-valved SAIF excels over a separate cylinder and remote valve when floor space is tight and running tubing back to a manifold is costly. The 4M310-10 valve offers a maximum frequency of 4 cycles per second. Select this specific DC24V terminal configuration for standard low-voltage control panels; the PT threaded ports match common tapered fittings. To replace this unit, match the 63mm bore, 400mm stroke, 3/8 inch valve port, DC24V voltage, terminal entry, and PT threads. Because the stroke is 400mm, ensure adequate guide support to prevent excessive side-loading on the rod. Standard carbon steel rod and no magnet (-S) are specified here.
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 SAIF63X400-10B FAQ
The 63mm bore generates 1559N of push force at 0.5 MPa and 2182N at 0.7 MPa. The integrated 4M310-10 5/2 valve provides an effective area of 30 mm2 (Cv 1.68) for air flow.
The 5/2 valve is internal piloted and holds its last position pneumatically, not by a spring. By default, the rod retracts when the DC24V coil is energised, but you can reposition the valve to extend-when-energised. It is not a load lock; use SAIL for holding.
