Airtac SAIF Series Standard Cylinder with Valve SAIF63X600-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X600-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 600mm 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 SAIF63X600-08B
The AirTAC SAIF63X600-08B is a double-acting ISO 15552 profile cylinder paired with a built-in 4M310-08 5/2 solenoid valve, offering a Cv of 1.40. Driven by a DC24V terminal coil consuming 3.0 W, it activates in 0.05 s or less with an IP65 rating. Because the integrated valve operates from 0.15 to 0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the bare cylinder rates to 1.0 MPa. At 0.5 MPa it delivers 1559 N of push force and 1402 N of pull force.
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. The manifold uses O10 x O6.5 PU tubing to bridge the 1/4" valve port and the 3/8" cylinder port. This self-contained design eliminates the need for a remote valve bank, reducing panel space and tubing runs for decentralized machine stations.

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 SAIF63X600-08B Is Used
Decentralized Assembly Lines
Eliminates remote valve banks by switching locally from a single DC24V signal, drastically reducing tubing runs across large automated assembly floors.
Material Handling Diverter
Provides 1559 N of push force at 0.5 MPa to actuate sorting gates, with the integrated 4M310-08 valve handling high cycle frequencies up to 4 cycles per second.
Space-Constrained Retrofitting
Ideal for upgrading older machinery where adding new valve manifolds is impossible, as the self-contained valved cylinder operates independently within a 0.15-0.8 MPa range.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X600-08B the Right Choice?
Choose this 63mm bore when a 50mm bore lacks sufficient thrust (the 50mm yields 982 N push at 0.5 MPa) or an 80mm bore is excessive (delivering 2513 N push at 0.5 MPa). A self-valved SAIF is ideal when installing a separate cylinder and remote valve would require extensive plumbing across a large machine. The DC24V terminal coil offers solid-state reliability, while the PT thread ensures a tight, tapered seal.
For a direct replacement, match the 63mm bore, 600mm stroke, 4M310-08 valve port, DC24V voltage, terminal entry, and standard carbon steel rod without a magnet. Because this stroke is 600mm (exceeding 300mm), ensure adequate side-load guidance to prevent rod binding and premature seal wear. Note that the built-in 5/2 valve routes air but does not hold the load without live pressure; for true mechanical locking, consider the SAIL series.
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 SAIF63X600-08B FAQ
The cylinder delivers 1559 N push and 1402 N pull force at 0.5 MPa. The built-in 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a maximum no-load frequency of 4 cycles per second.
No, the built-in 5/2 solenoid valve routes air but does not mechanically lock the load. The factory setting retracts the rod when the DC24V coil is energised, but it can be repositioned to extend-when-energised. For true load holding, consider the SAIL lock series.
