Airtac SAIF Series Standard Cylinder with Valve SAIF50X75-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X75-08B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 75mm stroke and a built-in 4M210-08 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 SAIF50X75-08B
The AirTAC SAIF50X75-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89 and 16.0 mm2 effective area. Driven by a DC24V terminal coil consuming 3.0 W, it activates in 0.05 s or less with IP65 protection. While the cylinder itself rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, making the practical working range for this assembled unit 0.15-0.8 MPa. At 0.5 MPa it generates 982 N of push force and 825 N of pull force.
By mounting the valve directly via a manifold block and O8 x O5 PU tubing, this unit switches itself from one coil signal, eliminating remote plumbing. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. The valve port is 1/4 inch, which differs from the cylinder port, and the assembly uses a carbon steel rod with PT tapered threads.

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 SAIF50X75-08B Is Used
Decentralized Stations
Perfect for large machines with decentralized stations, switching itself via one DC24V signal to cut remote plumbing.
Space-Tight Machines
Fits into compact assemblies where mounting a separate valve and running tubing is physically impossible.
Retrofit Automation
Ideal for upgrading existing lines where adding a central valve bank and long air lines is too costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X75-08B the Right Choice?
Choose this 50 mm bore when you need around 982 N of push force at 0.5 MPa; step down to a 40 mm bore for 628 N, or up to a 63 mm bore for 1559 N if your load requires more thrust. A self-valved SAIF beats a separate cylinder and remote valve when panel space is tight and running tubing across a large machine is costly, making it ideal for decentralized stations. Select this DC24V terminal entry model for standard low-voltage control panels.
For replacements, match the 50 mm bore, 75 mm stroke, 1/4 inch valve port, DC24V voltage, terminal entry, and PT thread. Note that the 5/2 valve routes air and is not a lock; the variable air cushion only decelerates near stroke end. If you need true load holding, consider the SAIL lock or BSAI clamp-lock series.
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 SAIF50X75-08B FAQ
The cylinder provides 982 N push and 825 N pull force at 0.5 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice with a Cv of 0.89.
It uses a 5/2 internal piloted solenoid valve. This specific model uses a DC24V terminal coil. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised, eliminating the need for a separate remote valve.
