Airtac SAIF Series Standard Cylinder with Valve SAIF63X350S-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X350S-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 SAIF63X350S-10B
The AirTAC SAIF63X350S-10B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-10 5/2 solenoid valve. This integrated valve provides an effective flow of 30.0 mm2 (Cv 1.68) and operates on DC24V power via a terminal connection, drawing just 3.0 W. Equipped with a standard carbon steel piston rod and an -S magnet, it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state sensors. The cylinder itself rates to 1.0 MPa, but because the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa.
By driving the cylinder directly from a single coil signal, this decentralized design eliminates remote plumbing and saves panel space. The manifold connects the valve to the cylinder using PU tubing (O10 x O6.5), and the valve port (10 / 3/8") is distinct from the cylinder port (PT3/8). 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 requires it. The 5/2 valve holds its position via internal pilot pressure, not a spring, meaning it routes air continuously but does not lock the load without live pressure.

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 SAIF63X350S-10B Is Used
Decentralized Automation Stations
Perfect for large-scale machinery where mounting valves directly at the actuator reduces wiring complexity and eliminates long pneumatic runs back to a central manifold.
Material Handling Diverters
Provides robust 1559N push force at 0.5 MPa for actuating heavy sorting gates and diverting mechanisms on high-speed production lines.
Space-Constrained Packaging
The integrated 4M310-10 valve and manifold block save valuable panel space, fitting into tight machine frames where separate valve islands are impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X350S-10B the Right Choice?
Choose this 63mm bore when you need substantial thrust, such as the 1559N push force at 0.5 MPa or 2182N at 0.7 MPa. If your application requires less force, stepping down to a 50mm bore yields 982N of push force at 0.5 MPa, while moving up to an 80mm bore provides 2513N. A self-valved SAIF is ideal for large machines with decentralized stations where running separate valve tubing is costly or space-prohibitive. For load-holding applications, note that neither the 5/2 valve nor the air cushions act as a brake; consider an AirTAC SAIL lock or BSAI clamp-lock cylinder instead. When ordering replacements, match the 63mm bore, 350mm stroke, 10 valve port, DC24V voltage, terminal entry, PT thread, and -S magnet. Because the stroke is 350mm, ensure adequate guiding to prevent rod side-loading and premature seal wear.
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 SAIF63X350S-10B FAQ
The 63mm bore generates 1559N of push force and 1402N of pull force at 0.5 MPa. The built-in 4M310-10 5/2 valve provides an effective area of 30.0 mm2 (Cv 1.68) with a maximum frequency of 4 cycles per second.
No, the 5/2 valve routes air but does not lock the load; it relies on internal pilot pressure to hold position and is not a mechanical brake. By default, the rod retracts when the DC24V coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
