Airtac SAIF Series Standard Cylinder with Valve SAIF63X350-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X350-10A 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 SAIF63X350-10A
The AirTAC SAIF63X350-10A 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 operates at a maximum frequency of 4 cycles per second. Driven by an AC220V coil with a standard terminal electrical entry, it consumes 3.5 VA and carries an IP65 rating with a 0.05s activation time. The cylinder itself features a carbon steel piston rod and PT tapered threads. Because the valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa rather than the 1.0 MPa rating of the bare cylinder.
By default, the piston rod retracts when the coil is energised, though this can be reconfigured to extend-when-energised by simply repositioning the valve. This self-switching design eliminates the need for remote plumbing, saving panel space and making it ideal for decentralized stations across large machines. The manifold connects the valve to the cylinder using O10 x O6.5 PU tubing, and it is important to note the valve port is 3/8 inch while the cylinder port is also 3/8 inch. At 0.5 MPa, this 63mm bore generates 1559N of push force and 1402N of pull force.

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)

| 0.7 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 SAIF63X350-10A Is Used
Decentralized Machine Stations
Eliminates long air lines by mounting the 4M310 valve directly on the cylinder, providing localized control across sprawling factory layouts.
Mid-Force Assembly Lines
Delivers 1559N of push force at 0.5 MPa, suited for pressing, clamping, and joining tasks on automated assembly machinery.
Retrofit Automation
Ideal for upgrading existing ISO 15552 fixtures where running new valve tubing is costly or space-prohibitive.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X350-10A the Right Choice?
Choose this self-valved SAIF model when you need to reduce tubing and wiring in decentralized layouts, as one coil signal directly drives the cylinder without a separate remote valve. If your application requires less force, stepping down to a 50mm bore yields 982N of push force at 0.5 MPa; if you need more power, an 80mm bore provides 2513N. Keep in mind that while the built-in 5/2 valve routes air to drive the motion, it does not hold the load without live pressure, so for locking applications consider the SAIL series instead.
Because this unit has a 350mm stroke, you should account for potential side loads and use appropriate guide rails to prevent rod damage. When ordering a replacement, verify the 63mm bore, 350mm stroke, 3/8 inch valve port, AC220V terminal coil, PT thread type, and the absence of a magnet (-S not specified). If position feedback is needed later, note that adding a magnet enables CMSE reed and DMSE electronic sensors.
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 SAIF63X350-10A FAQ
The 63mm bore generates 1559N of push force and 1402N of pull force at 0.5 MPa. The built-in 4M310-10 valve has a 30.0 mm2 orifice and a Cv of 1.68.
No, the integrated 4M310 5/2 valve switches the cylinder directly from an AC220V terminal coil signal. The factory setting retracts the rod when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
