Airtac SAIF Series Standard Cylinder with Valve SAIF63X250S-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X250S-10B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 250mm 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 SAIF63X250S-10B
The AirTAC SAIF63X250S-10B is a double-acting ISO 15552 profile cylinder with a built-in 4M310-10 5/2 solenoid valve, delivering a 1559 N push force at 0.5 MPa. Equipped with a magnet for CMSE reed and DMSE electronic sensors, this unit uses a DC24V terminal coil drawing 3.0 W. The integrated valve provides a 30.0 mm2 orifice (Cv 1.68) and switches up to 4 cycles per second. Because the valve manifold mounts directly using O10 x O6.5 PU tubing, you save panel space and eliminate remote plumbing.
While the bare cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The 3/8 inch valve port differs from the cylinder's PT3/8 port, so always distinguish the two during setup. This self-switching design excels in decentralized stations across large machines.

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 SAIF63X250S-10B Is Used
Decentralized Automation
Ideal for large factory stations where running individual valve tubing back to a main panel is costly; the self-contained 4M310 valve drives the cylinder directly from a single DC24V signal.
Mid-Force Positioning
Delivers 1559 N push force at 0.5 MPa for mid-sized machining and clamping tasks, offering a compact footprint without needing a separate remote valve assembly.
Material Handling
Provides reliable 250 mm stroke actuation for conveyor diverters and stops, with the built-in magnet allowing precise DMSE electronic sensor tracking at high speeds.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X250S-10B the Right Choice?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is insufficient, but a 80 mm bore (2513 N push at 0.5 MPa) is excessive. The integrated 4M310 valve removes the need for a separate remote valve, making it ideal for space-tight machines where running long tubing is costly. The DC24V terminal coil offers low 3.0 W power consumption with a fast 0.05 s activation time. If your stroke of 250 mm or longer involves heavy lateral loads, add an external guide to prevent rod side-load wear.
For load-holding applications, remember the 5/2 valve routes air but does not lock the piston; consider a SAIL lock cylinder instead. To replace this unit, match the 63 mm bore, 250 mm stroke, PT3/8 cylinder port, 3/8 inch valve port, DC24V voltage, terminal entry, PT thread, and the -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 SAIF63X250S-10B FAQ
At 0.5 MPa, the 63 mm bore provides 1559 N push and 1402 N pull force. The integrated 4M310-10 5/2 valve has a 30.0 mm2 effective area (Cv 1.68) and handles up to 4 cycles per second.
No, the built-in 4M310 valve switches the cylinder from a single DC24V terminal coil signal. By default, the rod retracts when energised, but you can reconfigure it to extend-when-energised by repositioning the valve.
