Airtac SAIF Series Standard Cylinder with Valve SAIF32X80-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X80-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 80mm 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 SAIF32X80-08B
The AirTAC SAIF32X80-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by a DC24V terminal entry coil consuming just 3.0 W, it delivers a 16.0 mm2 flow (Cv 0.89) directly to the 32mm bore. This self-contained assembly generates 402N of push force at 0.5 MPa. Because the built-in valve operates at 0.15-0.8 MPa, this defines the practical working range for the unit, even though the cylinder body itself rates to 1.0 MPa.
By switching itself from a single coil signal, it eliminates remote valves and excess tubing, making it perfect for decentralized stations. The manifold connects to the cylinder via an O8 x O5 PU tube, differing from the 1/8 cylinder port. Factory set to retract the carbon steel rod when energized, the valve can be repositioned to extend on signal. It uses adjustable air cushions at both ends to decelerate near stroke limits, but note this cushioning is not a load-holding lock.

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 SAIF32X80-08B Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve island on large machines, driving the 32mm bore directly from a local DC24V signal to save panel space.
Space-Constrained Automation
The integrated manifold and short PU tubing drastically reduce the envelope compared to a separate cylinder and valve setup in tight cells.
Retrofit & Upgrades
Ideal for upgrading existing ISO 15552 fixtures where adding long air lines for a new remote valve is impractical or expensive.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X80-08B the Right Choice?
Choose this 32mm bore when you need compact actuation up to 402N push force at 0.5 MPa; step up to the 40mm bore if your application requires 628N. The SAIF32X80-08B is ideal for space-tight machines where running separate valve tubing is costly, as the integrated 4M210 valve handles switching locally. It operates efficiently across the 30-800 mm/s speed range.
When ordering a replacement, verify the 80mm stroke, 1/8 cylinder port, 1/4 valve port, DC24V terminal coil, PT thread type, and standard carbon steel rod. If your machine requires position holding under load, note that the 5/2 valve routes air but does not lock the piston; consider the SAIL series for pneumatic locking 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 SAIF32X80-08B FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The integrated 4M210-08 5/2 valve has an effective flow area of 16.0 mm2 (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
No, the 4M210 valve is internally piloted and holds position via pilot pressure, not a spring. It operates on DC24V (3.0 W) with a terminal entry. Factory set to retract when energized, it can be reconfigured to extend when energized by repositioning the valve.
