Airtac SAIF Series Standard Cylinder with Valve SAIF63X125-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X125-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 125mm 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 SAIF63X125-08A
The AirTAC SAIF63X125-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve delivers a 25.0 mm2 effective area (Cv 1.40) and switches via an AC220V terminal connection, drawing 3.5 VA with an IP65 rating and a maximum 0.05 s response time. Because the manifold links the valve to the cylinder using O10 x O6.5 PU tubing, you save panel space and eliminate remote plumbing.
The bare cylinder rates to 1.0 MPa, but the practical operating range for this valved assembly is 0.15-0.8 MPa, yielding a push force of 1559 N at 0.5 MPa and 2182 N at 0.7 MPa. From the factory, the default setting retracts the piston rod when the coil is energised, though you can reposition the valve to extend on signal. The unit uses a carbon steel rod with PT tapered threads, and the cylinder port is 3/8 while the valve port is 1/4.

| 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 SAIF63X125-08A Is Used
Decentralized Automation
Ideal for large machines with multiple stations, eliminating long air lines by mounting the 4M310 valve directly on the cylinder for localized AC220V control.
Material Handling Diverters
Provides robust 1559 N push force at 0.5 MPa to actuate routing gates, with the integrated valve ensuring fast 4 cycle/sec switching without remote plumbing.
Compact Assembly Machines
Saves valuable panel space by bundling the ISO 15552 actuator and 5/2 valve together, simplifying wiring through the terminal electrical entry.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X125-08A the Right Choice?
Choose this 63 mm bore when a 50 mm cylinder lacks thrust, as the 50 mm bore provides 982 N push at 0.5 MPa compared to the 1559 N offered here. Stepping up to an 80 mm bore yields 2513 N at 0.5 MPa if your application demands higher load movement. This self-valved SAIF configuration excels in decentralized stations where running separate valve tubing is costly, as one AC220V coil signal directly drives the actuator.
For replacements, verify the 125 mm stroke, 3/8 cylinder port, 1/4 valve port, AC220V voltage, terminal entry, and PT threads. Note that the 5/2 valve routes air and is not a locking mechanism; if you need true load holding under zero pressure, select an AirTAC SAIL lock cylinder instead. The stroke is under the 1500 mm standard maximum, so no side-load guide is required.
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 SAIF63X125-08A FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and supports a maximum frequency of 4 cycles per second.
The factory default setting retracts the piston rod when the AC220V coil is energized. Because it uses a 5/2 pilot valve, you can reconfigure the unit to extend-when-energized simply by repositioning the valve on the manifold block, eliminating the need for a separate remote valve.
