Airtac SAIF Series Standard Cylinder with Valve SAIF32X450-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X450-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 450mm 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 SAIF32X450-08B
The AirTAC SAIF32X450-08B is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve, offering a Cv of 0.89. It features a 32mm bore generating 402N push force at 0.5 MPa and a 450mm stroke. Driven by a DC24V terminal entry coil consuming 3.0W, it eliminates the need for a remote valve bank, saving panel space and plumbing. The integrated manifold uses an O8xO5 PU tube to bridge the valve and cylinder, making it perfect for decentralized machine stations.
The assembled SAIF unit operates safely within 0.15-0.8 MPa, as the built-in valve limits the cylinder's 1.0 MPa rating. By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 valve holds its position via internal pilot pressure, not a spring, though it will not hold a suspended load without live pressure.

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 SAIF32X450-08B Is Used
Decentralized Stations
Ideal for large machines needing isolated control, using the DC24V terminal signal to actuate the cylinder without a central valve manifold.
Space-Tight Handling
Fits into compact assembly machinery where panel space is restricted, using the integrated 4M210 valve to minimize external plumbing.
Retrofit Automation
Perfect for upgrading existing lines where routing new air lines to a remote valve is difficult, offering a self-contained 5/2 switching solution.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X450-08B the Right Choice?
Select this 32mm bore model for compact decentralized stations where running separate valve tubing is costly. If your application requires more thrust, the 40mm bore variant provides 628N push force at 0.5 MPa. The 450mm stroke exceeds 300mm, so ensure adequate side-load guidance to prevent rod binding.
This configuration uses a 1/8 inch cylinder port and a 1/4 inch valve port. It features a standard carbon steel rod, PT tapered threads, and no magnet. For replacements, match the 450mm stroke, 4M210-08 valve, DC24V terminal coil, and 32mm bore exactly.
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 SAIF32X450-08B 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 max frequency of 5 cycles/sec.
No, the SAIF32X450-08B has a built-in 4M210 5/2 valve. It operates from a single DC24V terminal coil signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
