Airtac SAIF Series Standard Cylinder with Valve SAIF32X80S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X80S-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 SAIF32X80S-08B
The AirTAC SAIF32X80S-08B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. Delivering a Cv of 0.89, this self-contained unit eliminates remote plumbing and is ideal for decentralized machine stations. The DC24V terminal coil draws 3.0 W, features IP65 protection, and activates in 0.05 s. Because the 4M210 valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembled SAIF, even though the bare cylinder rates to 1.0 MPa.
Equipped with a magnet for CMSE reed and DMSE electronic sensors, this 32mm bore generates 402N of push force at 0.5 MPa. The manifold connects the valve to the cylinder using O8xO5 PU tubing, routing air to the PT1/8 cylinder ports. By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The carbon steel piston rod and tapered PT threads are standard.

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 SAIF32X80S-08B Is Used
Decentralized Assembly Stations
Eliminates the need for a central valve manifold on large machines by driving the 32mm bore directly from a local DC24V signal.
Space-Constrained Automation
The integrated 4M210 valve manifold saves valuable panel and tubing space in compact cell layouts.
Retrofit and Upgrades
Ideal for upgrading existing ISO 15552 cylinders where adding long pneumatic tubing runs for remote valves is impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X80S-08B the Right Choice?
Choose this self-valved SAIF assembly when panel space is tight and running separate valve tubing to a remote station is costly. If your application requires less force, there is no smaller bore in the SAIF range; if you need more power, stepping up to the 40mm bore yields 628N of push at 0.5 MPa. For higher flow requirements, a 4M310 valve on a larger bore offers more Cv.
When specifying a replacement, match the 32mm bore, 80mm stroke, 1/4" valve port, DC24V voltage, terminal electrical entry, PT thread type, and the -S magnet option. The 5/2 valve routes air to hold position pneumatically but does not mechanically lock the load; for true load-holding, consider the SAIL lock cylinder. Stroke is under 300mm, so standard guide rules apply without needing auxiliary side-load support.
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 SAIF32X80S-08B FAQ
The 32mm bore generates 402N of push force and 345N of pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve provides an effective flow area of 16.0 mm2 (Cv 0.89).
The built-in 5/2 valve allows the cylinder to switch itself from a single DC24V coil signal, reducing wiring and tubing for decentralized installations. By factory default, the rod retracts when energised, but repositioning the valve reconfigures it to extend-when-energised.
