Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 50mm 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 SAIF32X50S-08B
The AirTAC SAIF32X50S-08B is a double-acting profile cylinder with an integrated 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89 and a 16.0 mm2 effective orifice. Driven by a DC24V terminal coil consuming 3.0 W, it responds in 0.05 s with an IP65 rating. The cylinder body features a PT1/8 port and includes a magnet for CMSE reed or DMSE solid-state sensors. 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 rather than the 1.0 MPa rating of the bare cylinder.
This self-contained design eliminates remote plumbing, saving panel space and making it ideal for decentralized machine stations. The manifold connects to the cylinder via an O8 x O5 PU tube. From the factory, the piston rod retracts when the coil is energized, but you can reposition the valve to extend-when-energized. At 0.5 MPa, the 32 mm bore generates 402 N of push force and 345 N of pull force, while the valve itself supports up to 5 cycles per second.

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 (Ø32mm)

|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAIF32X50S-08B Is Used
Decentralized Assembly Stations
Ideal for large machines with multiple stations, eliminating long tubing runs by switching the 32 mm bore locally via the integrated 4M210 valve.
Compact Clamping Fixtures
Provides 402 N of push force at 0.5 MPa in tight spaces where mounting a separate remote valve and manifold block is physically impossible.
Retrofit Automation Upgrades
Simplifies machine upgrades by replacing a bare cylinder and remote valve assembly with a single self-switching unit driven by a DC24V signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08B the Right Choice?
Choose this 32 mm bore if your application requires around 402 N of push force at 0.5 MPa; stepping up to the 40 mm bore yields 628 N, while dropping to a smaller compact cylinder would sacrifice this thrust. The SAIF32X50S-08B is optimal when running separate valve tubing is costly or space-prohibitive, as the integrated 4M210 valve switches the cylinder directly from one DC24V terminal signal. It includes an -S magnet for position sensing. Remember that the 5/2 valve routes air but does not lock the load without live pressure; for true position holding, consider the SAIL lock cylinder. To replace this unit, match the 50 mm stroke, PT1/8 cylinder port, 1/4 inch valve port, DC24V terminal coil, and PT thread.
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 SAIF32X50S-08B FAQ
The 32 mm bore generates 402 N of push force and 345 N of pull force at 0.5 MPa. The integrated 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
Yes. The factory setting retracts the rod when the DC24V coil is energized, but you can reposition the integrated 5/2 valve to extend-when-energized. Because the valve is built-in, no separate remote valve is needed.
