Airtac SAIF Series Standard Cylinder with Valve SAIF32X350-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X350-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 350mm 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 SAIF32X350-08A
The AirTAC SAIF32X350-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This built-in valve delivers a 16.0 mm2 effective orifice (Cv 0.89) and operates at a maximum frequency of 5 cycles per second. Driven by an AC220V coil with a standard terminal electrical entry, it consumes 3.5 VA and responds in 0.05 seconds or less. The assembly operates within a practical 0.15-0.8 MPa pressure range, as the valve limits the cylinder's inherent 1.0 MPa capacity.
Providing 402N of push force at 0.5 MPa, this 32mm bore unit uses a carbon steel piston rod and PT1/4 cylinder ports. The valve connects to the cylinder via an O8 x O5 PU tube, meaning the 1/4-inch valve port differs from the cylinder's PT1/8 port. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. This decentralized design eliminates remote plumbing, saving panel space across large machines.

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 SAIF32X350-08A Is Used
Decentralized Assembly Stations
Ideal for large machines where running remote valve tubing is costly, this self-switching cylinder operates from a single AC220V signal to reduce panel space.
Long-Stroke Positioning
The 350mm stroke handles extended travel for part transfer, provided an external guide is used to manage side-load on the 12mm carbon steel rod.
Space-Constrained Retrofitting
Fits neatly into tight machine envelopes, using the integrated 4M210 valve and short PU tubing to eliminate bulky external pneumatic banks.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X350-08A the Right Choice?
Select this 32mm bore model when your application requires a 350mm stroke and moderate force; if you need significantly more thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. The 350mm stroke exceeds 300mm, so ensure you use a suitable guide to prevent excessive side-load on the piston rod. Choose this self-valved SAIF configuration over a separate cylinder and remote valve when you want to minimize tubing and wiring across decentralized stations. Since the 5/2 valve only routes air, it cannot hold the load without live pressure; for true position holding, consider the SAIL lock series instead. Replacement matches require the exact 32mm bore, 350mm stroke, 1/4-inch valve port, AC220V voltage, terminal entry, PT thread, and no 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 SAIF32X350-08A FAQ
The 32mm bore generates 402N of push force and 345N of pull force at 0.5 MPa. The built-in 4M210-08 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum operating frequency of 5 cycles per second.
No, the 5/2 solenoid valve routes air but does not lock the piston. By default, the rod retracts when the coil is energised, but it can be repositioned to extend on signal. For true position holding without live pressure, use a SAIL lock cylinder.
