Airtac SAIF Series Standard Cylinder with Valve SAIF32X75S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X75S-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm 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 SAIF32X75S-08B
The AirTAC SAIF32X75S-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. Driven by a DC24V terminal entry coil consuming 3.0 W, it integrates controls directly on the actuator. The carbon steel piston rod and -S magnet enable precise position sensing with AirTAC CMSE reed or DMSE electronic switches.
Because the 4M210 valve operates at 0.15-0.8 MPa, the practical working range for the assembled SAIF unit is 0.15-0.8 MPa, despite the cylinder body rating to 1.0 MPa. The factory default retracts the rod when the coil is energised, but you can reposition the valve to extend on signal. The manifold connects to the cylinder via PU tubing (O8 x O5), routing air from the 1/4" valve port to the 1/8" cylinder port.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF32X75S-08B Is Used
Decentralized Stations
Ideal for large machines with multiple nodes, eliminating long tubing runs back to a central manifold by switching locally via the integrated 4M210 valve.
Compact Assembly Lines
Fits space-tight machinery where mounting a separate valve is impossible, providing 402N of thrust with a built-in DC24V terminal connection.
Retrofit & Upgrades
Perfect for upgrading existing ISO 15552 setups where running new pneumatic tubing is costly, utilizing the existing DC24V electrical supply.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X75S-08B the Right Choice?
Choose this 32mm bore when you need 402N push force at 0.5 MPa; step up to the 40mm bore if your application requires 628N. The self-valved SAIF design eliminates the need for a separate remote valve, drastically reducing panel space and tubing runs for decentralized machine stations. It switches itself from one coil signal.
Remember that the 5/2 valve routes air and the end cushions only decelerate the piston near stroke end; neither function locks or holds the load. For position holding requirements, consider the SAIL lock variant. This exact replacement requires a 32mm bore, 75mm stroke, 4M210-08 valve (1/4" port), DC24V terminal coil, PT threads, and an -S 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 SAIF32X75S-08B FAQ
At 0.5 MPa, the 32mm bore provides 402N push and 345N pull force. The integrated 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89) and a maximum frequency of 5 cycles per second.
No, the SAIF32X75S-08B has a built-in 4M210 valve that controls the cylinder directly from the DC24V coil signal. By factory default, the piston rod retracts when energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
