Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-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 SAIF32X450S-08B
The AirTAC SAIF32X450S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by a DC24V terminal entry coil drawing 3.0 W, it delivers a Cv of 0.89 and generates 402N of push force at 0.5 MPa. Because the manifold block mounts directly to the cylinder using O8xO5 PU tubing, it eliminates the need for a separate remote valve, saving panel space and simplifying decentralized station wiring across large machines.
The assembled unit operates within a practical pressure range of 0.15-0.8 MPa, as the built-in valve limits the cylinder's 1.0 MPa base rating. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to achieve extend-when-energised operation. This 32mm bore variant includes a magnet for CMSE reed and DMSE electronic sensors, uses a carbon steel rod, and relies on adjustable air cushions at both ends to decelerate the 450mm stroke smoothly.

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 SAIF32X450S-08B Is Used
Decentralized Conveyor Diverters
Ideal for routing packages on long conveyor lines where running individual air tubes back to a main panel is costly and complex.
Compact Assembly Stations
Saves valuable panel space by integrating the 4M210 valve directly on the cylinder, perfect for densely packed automated machinery.
Machine Retrofits
Simplifies upgrades on older equipment by allowing a single DC24V electrical signal to control the actuator without adding new pneumatic manifolds.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X450S-08B the Right Choice?
Choose this self-valved SAIF unit when installing multiple actuators across a wide machine footprint, as routing a single electrical signal is far simpler than plumbing long air lines to a centralized valve bank. If your application requires less force, stepping down is not an option below 32mm, but if you need higher push force, the 40mm bore provides 628N at 0.5 MPa. Because the stroke is 450mm, ensure adequate guiding to prevent side-loading damage to the carbon steel rod. Remember that the 5/2 valve routes air but does not lock the load; for position holding without live pressure, consider an AirTAC SAIL lock cylinder instead. Replacement units must match the 32mm bore, 450mm stroke, 4M210-08 valve, DC24V terminal coil, PT threads, and -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 SAIF32X450S-08B FAQ
At 0.5 MPa, this 32mm bore cylinder generates 402N of push force and 345N of pull force. The integrated 4M210-08 5/2 valve provides an effective flow area of 16.0 mm2 (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
No, the SAIF series features a built-in 4M210 valve manifold, so it switches itself from one DC24V coil signal. By default, the rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
