Airtac SAIF Series Standard Cylinder with Valve SAIF63X350-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X350-10B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 350mm 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 SAIF63X350-10B
The AirTAC SAIF63X350-10B 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 a 30 mm2 effective orifice, driving the 63mm bore to 1559N push force at 0.5MPa. It is configured with a DC24V terminal coil drawing 3.0W, protected to IP65 and responding in 0.05s. Because the valve operates at 0.15-0.8MPa, this defines the practical working pressure for the assembled unit, even though the cylinder body rates to 1.0MPa.
By integrating the valve directly on a manifold block, this unit eliminates remote plumbing and saves panel space for decentralized machine stations. The manifold connects to the cylinder via O10xO6.5 PU tubing, keeping the valve port (3/8) distinct from the cylinder port (3/8). From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence demands it.

| 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 SAIF63X350-10B Is Used
Decentralized Automation Stations
Ideal for large machines where running individual valve tubing back to a central manifold is costly. The built-in 4M310 valve lets the 63mm cylinder switch itself locally from a single DC24V signal.
Long-Stroke Assembly Presses
With a 350mm stroke and 1559N push force at 0.5MPa, it handles extended reach clamping and pressing tasks. Ensure external guide rails are used to manage side loads over this long stroke.
Space-Constrained Machine Retrofits
Eliminates the need for a separate remote valve bank, freeing up valuable panel space. The manifold and O10xO6.5 PU tubing keep the pneumatic routing compact and directly on the actuator.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X350-10B the Right Choice?
Choose this self-valved SAIF63X350-10B assembly when you need decentralized actuation without routing separate valve tubing across a large machine. It delivers 1559N push force at 0.5MPa; stepping down to a 50mm bore yields 982N, while stepping up to an 80mm bore provides 2513N. The 350mm stroke requires attention to side loads, so ensure proper guide rails to prevent rod binding. With a DC24V terminal connection and PT tapered threads, matching a replacement requires the exact bore, stroke, 3/8 valve port, DC24V voltage, and terminal entry.
Because the 5/2 valve routes air via internal pilot, it holds its last position pneumatically but does not mechanically lock the load. If your application requires true position holding without live pressure, consider the AirTAC SAIL lock cylinder or BSAI clamp-lock series instead. The integrated valve supports a maximum frequency of 4 cycles per second, making it suitable for moderate-speed automation.
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 SAIF63X350-10B FAQ
At 0.5MPa, the 63mm bore provides 1559N of push force and 1402N of pull force. The practical operating pressure for the assembled unit is 0.15-0.8MPa, limited by the built-in 4M310-10 valve, even though the cylinder body itself rates to 1.0MPa.
No, the integrated 4M310-10 5/2 solenoid valve controls the cylinder directly from a DC24V terminal coil signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised. The valve holds its position via internal pilot pressure, but it is not a mechanical lock.
