Airtac SAIF Series Standard Cylinder with Valve SAIF50X75S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X75S-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 SAIF50X75S-08B
The AirTAC SAIF50X75S-08B is a double-acting ISO 15552 profile cylinder with an integrated 4M210-08 5/2 solenoid valve, providing a Cv of 0.89. Driven by a DC24V terminal coil consuming 3.0 W, it eliminates remote plumbing. The cylinder body rates to 1.0 MPa, but the internal piloted valve limits the practical SAIF operating range to 0.15-0.8 MPa. At 0.5 MPa this 50mm bore generates 982N push force, stepping up to 1767N at 0.9 MPa.
This assembly includes a magnet for CMSE reed and DMSE electronic sensors. The factory setting retracts the rod when the coil is energised, which you can reconfigure to extend-when-energised by repositioning the valve. The manifold connects to the cylinder via O8 x O5 PU tubing, meaning the 1/4" valve port differs from the cylinder's own 1/4" port. It switches itself from one coil signal, saving panel space in decentralized 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 SAIF50X75S-08B Is Used
Decentralized Assembly Stations
Ideal for large machines with decentralized stations, eliminating long valve tubing runs by controlling the cylinder directly from a single DC24V coil signal.
Space-Constrained Tooling
The built-in 4M210-08 valve manifold saves valuable panel space and reduces plumbing complexity in tight retrofit applications.
Material Handling Diverter
Provides reliable 982N push force at 0.5 MPa for diverter arms, with the integrated valve ensuring fast 5 cycles/sec switching.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X75S-08B the Right Choice?
Choose this 50mm bore when 982N push force at 0.5 MPa is sufficient, or step down to the 40mm bore (628N push) for lighter loads. Step up to the 63mm bore (1559N push) if you need greater thrust. A self-valved SAIF beats a separate cylinder and remote valve by cutting tubing, wiring, and panel space, making it ideal for decentralized machine stations. The 5/2 valve routes air but does not lock the load; for position holding under pressure loss, consider the SAIL lock series. Side-load guides are generally unnecessary at this 75mm stroke.
When replacing, match the 50mm bore, 75mm stroke, 1/4" valve port, DC24V voltage, terminal entry, PT thread, and the -S magnet requirement.
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 SAIF50X75S-08B FAQ
The 50mm bore generates 982N push and 825N pull force at 0.5 MPa, reaching 1767N push at 0.9 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice and a Cv of 0.89.
It uses a 5/2 solenoid valve that holds position by pilot pressure, not a spring. The DC24V terminal coil draws 3.0 W with an IP65 rating. By factory default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
