Airtac SAIF Series Standard Cylinder with Valve SAIF63X700S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X700S-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 700mm 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 SAIF63X700S-08B
The AirTAC SAIF63X700S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective area. Driven by a DC24V terminal coil drawing 3.0 W with IP65 protection and a 0.05 s response time, it integrates switching directly on the actuator. The cylinder features a PT3/8 port and a carbon steel piston rod, while the valve manifold connects via a PU10x6.5 tube. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the bare cylinder rates to 1.0 MPa.
By default, the factory valve setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This decentralized design eliminates the need for a remote valve, reducing plumbing and panel space across large machines. The -S magnet option supports CMSE reed and DMSE electronic sensors for precise position detection.

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 SAIF63X700S-08B Is Used
Decentralized Automation Stations
Ideal for large machines with multiple zones, mounting the valve directly on the cylinder to eliminate long pneumatic lines and reduce response lag.
Space-Constrained Machinery
Perfect for tight installations where a separate valve island would consume valuable panel space, using the integrated 4M310 valve to save footprint.
Material Handling Retrofits
Suits upgrading existing conveyor diverter systems where running new valve tubing is costly, leveraging the 1559N push force for heavy product routing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X700S-08B the Right Choice?
Choose this 63mm bore when you need higher thrust than the 50mm version (which offers 982N push at 0.5 MPa) but want to avoid the larger envelope of the 80mm bore. At 0.5 MPa, this cylinder provides 1559N of push force and 1402N of pull force. The self-valved SAIF architecture is ideal for decentralized stations where running separate valve tubing is costly or space-prohibitive, allowing one coil signal to drive the actuator directly. The 4M310 valve offers a max frequency of 4 cycles per second.
For this 700mm stroke, ensure adequate side-load guidance to prevent rod bending, as the air cushion (30mm) only decelerates near stroke end. Remember that the built-in 5/2 valve routes air but does not lock the load; if you need true position holding without live pressure, consider the SAIL lock or BSAI clamp-lock series. When ordering a replacement, match the 63mm bore, 700mm stroke, PT3/8 cylinder port, 1/4 valve port, DC24V voltage, terminal entry, PT thread, and -S 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 SAIF63X700S-08B FAQ
At 0.5 MPa, the 63mm bore provides 1559N of push force and 1402N of pull force. The built-in 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
The DC24V terminal coil switches the 5/2 valve, which by factory default retracts the rod when energised but can be repositioned to extend-when-energised. The valve routes air but does not lock the load without live pressure; for true holding, use the SAIL or BSAI series.
