Airtac SAIF Series Standard Cylinder with Valve SAIF50X450-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X450-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 450mm 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 SAIF50X450-06B
The AirTAC SAIF50X450-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This built-in valve provides a Cv of 0.78 with a 14.0 mm2 orifice, operating at a maximum frequency of 5 cycles per second. Configured with a DC24V terminal electrical entry, the coil consumes 3.0 W, features IP65 protection, and activates in 0.05 seconds or less. Although the cylinder body rates to 1.0 MPa, the integrated valve limits the practical working pressure range to 0.15-0.8 MPa.
This assembly delivers 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa. The manifold connects to the cylinder using O8 x O5 PU tubing, meaning the 1/8" valve port differs from the 1/4" cylinder port. 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. This self-switching design eliminates the need for a separate remote valve, saving panel space and simplifying decentralized station installations.

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 SAIF50X450-06B Is Used
Decentralized Machine Stations
Ideal for large machines with multiple stations, eliminating long tubing runs from a central manifold by controlling the cylinder directly at the point of action.
Space-Constrained Automation
Perfect for tight enclosures where mounting a separate directional control valve is impossible, saving valuable panel and floor space.
Retrofit and Upgrades
Simplifies pneumatic system upgrades by replacing a standard cylinder and remote valve setup with a single, self-switching unit driven by one coil signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X450-06B the Right Choice?
Choose this 50 mm bore 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, while upgrading to a 63 mm bore provides 1559 N. A self-valved SAIF unit is ideal over a plain SAI cylinder with a remote valve when you want to minimize plumbing and wiring across decentralized machine stations. The DC24V terminal coil and PT thread are standard, but if you need position feedback, specify the -S option for CMSE reed or DMSE electronic sensors.
With a 450 mm stroke, this cylinder requires careful mounting to prevent excessive side loading; use FA or LB supports and guide the load rigidly. Remember that the 5/2 valve routes air but does not lock the load without live pressure. If your application demands mechanical load-holding, consider the SAIL lock or BSAI clamp-lock variants instead. For replacement, match the 50 mm bore, 450 mm stroke, 06 valve port, DC24V voltage, terminal entry, PT thread, and no 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 SAIF50X450-06B FAQ
The 50 mm bore generates 982 N push force at 0.5 MPa and 1767 N at 0.9 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
No separate remote valve is needed because the 5/2 valve is built-in. By factory default, the rod retracts when the DC24V coil is energised, but you can reposition the valve to make it extend-when-energised instead.
