Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 500mm 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 SAIF32X500S-08A
The AirTAC SAIF32X500S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific SKU specifies an AC220V terminal coil, a PT1/4 valve port, and a carbon steel piston rod. The built-in valve delivers a 16.0 mm2 flow (Cv 0.89) and switches at up to 5 cycles per second. Because the cylinder body rates to 1.0 MPa but the internal valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa.
By driving the cylinder directly from one coil signal, it eliminates remote plumbing and saves panel space for decentralized installations. The manifold connects to the cylinder via O8 x O5 PU tubing, while the factory default setting retracts the rod when the coil is energised, which can be reconfigured to extend-when-energised by repositioning the valve. This unit includes a magnet (-S) for CMSE reed and DMSE electronic sensors.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF32X500S-08A Is Used
Decentralized Stations
Eliminates the need for a remote valve bank, allowing independent control of clamping arms across large automated assembly lines.
Space-Tight Diverters
Fits into compact machinery envelopes where external plumbing is restrictive, using the built-in 5/2 valve to actuate sorting gates.
Retrofit Automation
Ideal for upgrading legacy pneumatic setups where adding new valve manifolds and extensive tubing runs is impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08A the Right Choice?
Choose this 32mm bore when you need 402N push force at 0.5MPa, stepping up to the 40mm bore yields 628N if your load demands more. The self-valved SAIF architecture is optimal for machines where routing air tubing to a remote valve is costly or space-prohibitive. This model uses an AC220V terminal electrical entry with PT tapered threads. For position feedback, pair the integrated magnet with AirTAC CMSE or DMSE switches. The 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock variant.
At 500mm stroke, the rod is susceptible to side loads, so ensure external guide rails are used to prevent binding. To replace this unit, match the 32mm bore, 500mm stroke, 4M210-08 valve, AC220V 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 SAIF32X500S-08A FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The integrated 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89).
No, it features a built-in 4M210 5/2 valve driven by an AC220V terminal coil. By default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
