Airtac SAIF Series Standard Cylinder with Valve SAIF50X250-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X250-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 250mm stroke and a built-in 4M210-06 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 SAIF50X250-06B
The AirTAC SAIF50X250-06B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering a 0.78 Cv flow rate. Driven by a DC24V terminal entry coil drawing 3.0 W, it responds in 0.05 s. Because the cylinder body rates to 1.0 MPa but the internal valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. It generates 982 N of push force at 0.5 MPa.
From the factory, the piston rod retracts when the coil is energised, though you can reposition the valve to extend-when-energised if needed. The manifold connects to the barrel using O8 x O5 PU tubing, and the valve port (1/8 inch) differs from the 1/4 inch cylinder port. By switching itself from one coil signal, it eliminates remote plumbing and saves panel space 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAIF50X250-06B Is Used
Decentralized Assembly Lines
Ideal for large machines with multiple stations, eliminating long tubing runs by switching locally via the built-in valve.
Compact Clamping Fixtures
Saves panel space by integrating the 4M210 valve directly on the cylinder, providing 982 N of clamping force without remote plumbing.
Retrofits and Upgrades
Perfect for upgrading existing ISO 15552 setups where running new valve tubing is costly, using a simple DC24V terminal connection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X250-06B the Right Choice?
Choose this 50 mm bore if you need 982 N push force at 0.5 MPa; stepping down to a 40 mm bore drops output to 628 N, while an 80 mm bore yields 2513 N. A self-valved SAIF beats a separate cylinder and remote valve when you want to minimize wiring and tubing across decentralized stations. This DC24V terminal entry configuration with PT threads suits standard industrial controls. Since the stroke is 250 mm, ensure adequate guiding to prevent side-load wear.
For replacements, match the 50 mm bore, 250 mm stroke, 1/8 inch valve port, 1/4 inch cylinder port, DC24V coil, terminal entry, PT thread type, and standard carbon steel rod. Note that the 5/2 valve routes air and is not a lock; if you need load-holding, consider the SAIL lock variant. This unit lacks a magnet, so CMSE or DMSE sensors cannot be used without upgrading to an -S model.
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 SAIF50X250-06B FAQ
At 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. The integrated 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, it switches itself using the built-in 5/2 valve driven by a DC24V terminal coil. By default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
