Airtac SAIF Series Standard Cylinder with Valve SAIF63X150-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X150-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 150mm 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 SAIF63X150-08B
The AirTAC SAIF63X150-08B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. This integrated manifold block uses a PU tube (O10 x O6.5) to connect the valve to the cylinder, eliminating the need for separate remote plumbing. Driven by a DC24V terminal entry coil that consumes 3.0 W and responds in 0.05 s, it delivers a robust 1559 N push force at 0.5 MPa. Because the 4M310 valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is capped at 0.8 MPa rather than the bare cylinder's 1.0 MPa rating.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design is ideal for decentralized installation across large machines, as a single electrical signal drives the actuator without eating up panel space. The 3/8 cylinder port and 1/4 valve port are distinct, ensuring optimal flow control tailored to the 63 mm bore.

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 SAIF63X150-08B Is Used
Decentralized Automation Stations
Ideal for large machines where running individual valve tubing back to a central manifold is costly, allowing local control via a single DC24V signal.
Mid-Force Assembly Lines
Provides 1559 N of push force at 0.5 MPa for precise pressing, clamping, and joining tasks in confined equipment footprints.
Space-Tight Machine Retrofits
Integrates the valve and cylinder into one envelope, making it perfect for upgrading older machines where panel space for external valves is unavailable.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X150-08B the Right Choice?
Choose this 63 mm bore when a 50 mm bore (offering 982 N push at 0.5 MPa) is insufficient, but an 80 mm bore (delivering 2513 N push) would be excessive for your space constraints. The SAIF63X150-08B is preferred over a standard cylinder with a remote valve when you want to minimize tubing and wiring across decentralized stations. Remember that the built-in 5/2 valve routes air but does not lock the load; for position holding without live pressure, consider the SAIL lock or BSAI clamp-lock series. For replacement, verify the 63 mm bore, 150 mm stroke, 3/8 cylinder port, DC24V voltage, terminal entry, PT thread, and absence of a magnet.
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 SAIF63X150-08B FAQ
The 63 mm bore generates 1559 N push and 1402 N pull at 0.5 MPa. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
The built-in 5/2 valve allows the cylinder to switch itself from one coil signal without a remote valve, saving space and tubing. The factory setting retracts the rod when the DC24V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
