Airtac SAIF Series Standard Cylinder with Valve SAIF32X160S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X160S-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 160mm 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 SAIF32X160S-08B
The AirTAC SAIF32X160S-08B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This integrated manifold uses an O8xO5 PU tube to connect the valve to the cylinder, which has a PT1/8 cylinder port and a PT1/4 valve port. Driven by a DC24V terminal entry coil drawing 3.0 W with IP65 protection and a 0.05s response time, it delivers a push force of 402N at 0.5 MPa. Because the valve operates at 0.15-0.8 MPa, the practical working range for the assembled SAIF unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa.
By default, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This self-switching design means no separate remote valve is required, saving panel space and making it ideal for decentralized stations across large machines. This unit includes a magnet for position sensing with AirTAC CMSE reed or DMSE electronic sensors.

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 SAIF32X160S-08B Is Used
Decentralized Stations
Ideal for large machines with decentralized stations, eliminating long valve tubing runs by switching directly from a single DC24V signal.
Compact Assembly Machines
Saves valuable panel space in tight assembly machines by integrating the 4M210 valve and manifold directly onto the 32mm profile cylinder.
Retrofit Automation
Perfect for retrofits where running new pneumatic tubing to a remote valve bank is costly, offering a self-contained actuation solution.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X160S-08B the Right Choice?
Choose this 32mm bore if your application requires around 402N push force at 0.5 MPa; step up to the 40mm bore if you need 628N. The self-valved SAIF architecture beats a separate cylinder and remote valve when you want to minimize tubing and wiring in decentralized layouts. For stroke lengths of 160mm or more, ensure you provide adequate side-load guidance to prevent rod wear. To replace this unit, match the 32mm bore, 160mm stroke, 4M210-08 valve port, DC24V voltage, PT thread, terminal entry, and the -S magnet. Remember that the built-in 5/2 valve routes air but does not lock the load; for position holding without live pressure, consider the SAIL lock cylinder.
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 SAIF32X160S-08B FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5 MPa. The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89) and a maximum frequency of 5 cycles per second.
No, the integrated 4M210 5/2 valve switches the cylinder directly from a DC24V terminal coil signal. By factory default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
