Airtac SAIF Series Standard Cylinder with Valve SAIF32X200S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X200S-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 200mm 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 SAIF32X200S-08B
The AirTAC SAIF32X200S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89 and a 16.0 mm2 effective orifice. Driven by a DC24V terminal-entry coil consuming 3.0 W, it activates in 0.05 s or less with IP65 protection. Because the manifold links the valve to the cylinder via O8 x O5 PU tubing, the assembled unit operates within a practical 0.15-0.8 MPa range, despite the bare cylinder rating of 1.0 MPa. This 32 mm bore generates 402 N of push force at 0.5 MPa.
Featuring a magnet for position sensing, this model supports AirTAC CMSE reed and DMSE electronic sensors. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design eliminates the need for a remote valve, reducing plumbing and panel space for decentralized machine stations.

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 SAIF32X200S-08B Is Used
Decentralized Machine Stations
Ideal for large machines where running individual valve tubing back to a main panel is costly, allowing local control from a single DC24V signal.
Compact Assembly Automation
Suits space-tight machinery by combining the actuator and 4M210 valve into one envelope, freeing up valuable panel and framework area.
Retrofit and Upgrades
Perfect for upgrading existing ISO 15552 cylinder footprints where adding a separate remote valve would require extensive replumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X200S-08B the Right Choice?
Choose this self-valved SAIF unit when a decentralized station requires a compact 32 mm bore and 200 mm stroke; stepping up to a 40 mm bore yields 628 N push force at 0.5 MPa if your load demands greater thrust. The integrated 4M210-08 valve (1/4" valve port) and 1/8" cylinder port keep tubing runs minimal, while the DC24V terminal coil simplifies wiring. Since the stroke is 200 mm, ensure adequate guide support to manage side loads and prevent rod deflection. For exact replacements, match the 32 mm bore, 200 mm stroke, 1/4" valve port, DC24V voltage, terminal entry, PT thread, and the -S magnet option.
Remember that the built-in 5/2 valve routes air but does not lock the load; if your application requires true load-holding without live pressure, consider the SAIL lock cylinder or BSAI clamp-lock series instead.
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 SAIF32X200S-08B FAQ
The 32 mm bore generates 402 N of push force and 345 N of pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
No separate remote valve is needed. The integrated 5/2 solenoid valve switches the cylinder directly from a DC24V terminal coil signal. Factory-set to retract when energised, the valve can be repositioned to extend-when-energised, and it holds position via internal pilot pressure, not a spring.
