Airtac SAIF Series Standard Cylinder with Valve SAIF63X250-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X250-10B 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 SAIF63X250-10B
The AirTAC SAIF63X250-10B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This built-in valve provides a high flow rate with a 30.0 mm2 orifice (Cv 1.68) and operates at a maximum frequency of 4 cycles per second. Equipped with a DC24V terminal electrical entry, the coil consumes 3.0 W, features IP65 protection, and activates in 0.05 s or less. Because the valve manifold mounts directly to the profile barrel using O10 x O6.5 PU tubing, it eliminates remote plumbing and saves panel space.
While the cylinder body itself rates to 1.0 MPa, the practical operating pressure for the assembled SAIF unit is 0.15-0.8 MPa, matching the internal piloted valve limits. In its factory setting, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. Delivering 1559 N of push force at 0.5 MPa, this self-switching actuator is ideal for 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 SAIF63X250-10B Is Used
Decentralized Machine Stations
Eliminates the need for a remote valve island on large equipment. The integrated 4M310 valve lets this 63 mm bore cylinder switch itself directly from a single DC24V signal.
Material Handling Diverters
Provides 1559 N of push force at 0.5 MPa for routing heavy packages. The self-contained valving reduces tubing runs along the conveyor frame.
Space-Tight Retrofits
Ideal for upgrading older machines where routing new valve tubing is costly. The terminal entry and built-in manifold simplify electrical and air connections.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X250-10B the Right Choice?
Choose this 63 mm bore when you need more thrust than a 50 mm cylinder (which provides 982 N push at 0.5 MPa) but want to avoid the larger envelope of an 80 mm unit (2513 N push). The 4M310-10 valve offers a 3/8" valve port, while the cylinder port is also PT 3/8". If your layout requires holding a load without live air pressure, note that the 5/2 valve routes air but does not lock the piston; you should look at the SAIL lock variant instead. For this 250 mm stroke, ensure adequate side-load guidance to prevent rod binding.
When replacing this unit, verify the 63 mm bore, 250 mm stroke, 3/8" valve port, DC24V voltage, terminal entry, PT thread, and standard carbon steel rod. Because it lacks the -S magnet, it cannot host CMSE reed or DMSE electronic sensors without changing the rod assembly.
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 SAIF63X250-10B FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. The integrated 4M310-10 5/2 valve has an effective area of 30.0 mm2 (Cv 1.68) and supports up to 4 cycles per second.
The 5/2 valve is internal piloted and holds its last position via pilot pressure, not a spring. By default, energising the DC24V coil retracts the rod, but you can reconfigure it to extend-when-energised by repositioning the valve on the manifold.
