Airtac SAIF Series Standard Cylinder with Valve SAIF50X150-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X150-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 150mm 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 SAIF50X150-06B
The AirTAC SAIF50X150-06B is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring a built-in 4M210-06 5/2 solenoid valve. This integrated valve provides an effective area of 14.0 mm2 (Cv 0.78) and routes air directly through a manifold block using PU tubing (O8 x O5). Equipped with a DC24V terminal electrical entry, the coil consumes 3.0 W, features IP65 protection, and activates in 0.05 s or less. The cylinder bore is 50 mm with a 150 mm stroke, generating 982 N of push force at 0.5 MPa.
Because the built-in valve operates at 0.15-0.8 MPa, the practical working range for the assembled SAIF unit is 0.15-0.8 MPa, even though the cylinder body itself rates to 1.0 MPa. By default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. This self-switching design eliminates remote valves and extra tubing, making it 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 (Ø50mm)

|---|---|---|
| 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 SAIF50X150-06B Is Used
Decentralized Assembly Lines
Ideal for large machines with decentralized stations, eliminating the need for a remote valve bank and extensive pneumatic plumbing.
Space-Constrained Mechanisms
Fits into compact machinery where panel space is limited, driving 982 N of push force directly from a single DC24V signal.
Retrofit Automation
Perfect for upgrading older equipment where adding separate valves and tubing is costly, utilizing the built-in 4M210 valve.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X150-06B the Right Choice?
Choose this 50 mm bore model when your application requires around 982 N of push force at 0.5 MPa. If you need less force, stepping down to a 40 mm bore yields 628 N of push force, while stepping up to a 63 mm bore provides 1559 N. The SAIF50X150-06B is optimal for space-tight machines where running separate valve tubing is costly, as one DC24V coil signal drives the entire cylinder. The integrated 4M210-06 valve uses a PT1/8 port, while the main cylinder port is PT1/4.
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 AirTAC SAIL lock cylinder instead. For replacements, verify the 50 mm bore, 150 mm stroke, 06 valve port, DC24V voltage, terminal entry, PT thread, and the absence of a magnet (-S).
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 SAIF50X150-06B FAQ
The 50 mm bore generates 982 N of push force and 825 N of pull force at 0.5 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
The factory setting retracts the rod upon energizing, but it can be reconfigured to extend-when-energised by repositioning the valve. No separate remote valve is needed because the 5/2 valve is built directly into the manifold.
