Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 300mm 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 SAIF32X300S-08A
The AirTAC SAIF32X300S-08A is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve, offering a Cv of 0.89. Driven by an AC220V coil with a terminal electrical entry, it consumes 3.5 VA and features IP65 protection with a 0.05s response time. The integrated valve routes air through an O8xO5 PU tube to the PT1/8 cylinder ports, meaning the 1/4 inch valve supply port differs from the cylinder connection. Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic sensors for precise position detection.
While the bare cylinder rates to 1.0 MPa, the practical working pressure for this valved assembly is 0.15-0.8 MPa. It delivers 402N of push force at 0.5 MPa. 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-contained design eliminates the need for a separate remote valve, reducing panel space and tubing 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 SAIF32X300S-08A Is Used
Decentralized Stations
Perfect for large machines with multiple stations, eliminating long pneumatic tubing runs by switching locally via a single AC220V signal.
Compact Assembly
Fits into tight machine envelopes where a separate valve manifold would consume too much space, providing 402N of push force.
Retrofit Automation
Ideal for upgrading existing lines where adding new valve banks is impractical, leveraging the built-in 4M210-08 valve for standalone control.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08A the Right Choice?
Choose this 32mm bore when you need compact actuation with moderate force; stepping up to the 40mm bore yields 628N push at 0.5 MPa if your load demands more thrust. The SAIF32X300S-08A excels in decentralized installations where running separate valve tubing is costly, as one AC220V terminal signal drives the cylinder directly. At a 300mm stroke, ensure you provide adequate side-load guidance to prevent rod binding, as the air cushions (27mm) only decelerate near stroke ends.
For replacements, match the 32mm bore, 300mm stroke, 4M210-08 valve with a 1/4 inch port, AC220V voltage, terminal entry, PT thread, and the -S magnet. Remember that the 5/2 valve holds its position via internal pilot pressure, not a spring. If your application requires true load-holding without live pressure, look to the SAIL lock or BSAI clamp-lock cylinders 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 SAIF32X300S-08A FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5 MPa. The built-in 4M210-08 valve has a 16.0mm2 orifice with a Cv of 0.89, supporting a maximum frequency of 5 cycles per second.
Yes, the factory setting retracts the rod when the AC220V coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The built-in valve eliminates the need for a separate remote valve, saving wiring and panel space in decentralized setups.
