Airtac SAIF Series Standard Cylinder with Valve SAIF50X200-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X200-08B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 200mm 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 SAIF50X200-08B
The AirTAC SAIF50X200-08B is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring an integrated 4M210-08 5/2 solenoid valve. This valve provides a 16.0 mm2 effective area (Cv 0.89) and operates 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.
Because the cylinder rates to 1.0 MPa but the built-in valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The 50 mm bore generates 982 N of push force at 0.5 MPa. The manifold connects using PU tube (O8 x O5), and the valve port (1/4 inch) differs from the cylinder port (1/4 inch). By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve.

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 SAIF50X200-08B Is Used
Decentralized Stations
Eliminates remote valve plumbing by driving the cylinder directly from one coil signal, saving panel space across large machine layouts.
Space-Tight Machines
The integrated manifold block shortens the overall tubing run, fitting easily into compact assemblies where external valves cannot be mounted.
Retrofit Installations
Ideal for upgrading existing lines where running new valve tubing is costly, as the 5/2 valve and cylinder operate as a single unit.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X200-08B the Right Choice?
Choose this 50 mm bore when a 40 mm bore (628 N push at 0.5 MPa) is insufficient, or step up to a 63 mm bore (1559 N push at 0.5 MPa) if your load demands greater force. A self-valved SAIF beats a separate cylinder and remote valve by eliminating tubing and saving panel space, making it ideal for decentralized stations across large machines. It switches itself from one coil signal.
For load holding, note that the 5/2 valve routes air and is not a lock; the air cushion only decelerates near stroke end. For secure position holding, consider the SAIL lock series. To replace this unit, match the 50 mm bore, 200 mm stroke, 1/4 inch valve port, DC24V terminal coil, PT thread, and no magnet. With a 200 mm stroke, side-load is minimal, but always ensure proper guide alignment for smooth operation.
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 SAIF50X200-08B FAQ
The 50 mm bore provides 982 N of push force and 825 N of pull force at 0.5 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice with a Cv of 0.89.
The 5/2 valve routes air but does not lock the load; use the SAIL series for load holding. Factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised.
