Airtac SAIF Series Standard Cylinder with Valve SAIF80X125-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X125-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 125mm stroke and a built-in 4M310-08 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 SAIF80X125-08A
The AirTAC SAIF80X125-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with an AC220V terminal-entry coil that draws 3.5 VA, activates in 0.05 s, and carries an IP65 rating. The built-in valve provides an effective flow area of 25.0 mm2 (Cv 1.40) and uses a 1/4" valve port, while the cylinder itself features a 3/8" port. Because the valve operates from 0.15-0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the bare cylinder rates to 1.0 MPa.
In this 80mm bore configuration, the cylinder delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, scaling up to 4523 N push at 0.9 MPa. The manifold connects to the cylinder using O10 x O6.5 PU tubing. By default, the factory setting retracts the piston rod when the coil is energised, but this can be reconfigured 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 runs for decentralized machine stations.

| 0.7 MPa | 3519 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 SAIF80X125-08A Is Used
Decentralized Assembly Stations
Eliminates the need for remote valve banks on large machines by integrating the 4M310 valve directly, reducing pneumatic tubing and electrical wiring complexity.
High-Force Clamping Fixtures
Provides 2513 N of push force at 0.5 MPa directly at the point of operation, ideal for securing heavy workpieces without external plumbing.
Space-Constrained Automation
Fits into tight machine envelopes where a standard ISO 15552 cylinder and separate valve would exceed available space, driven by a single AC220V signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X125-08A the Right Choice?
Select this 80mm SAIF unit when your application requires substantial thrust (2513 N push at 0.5 MPa) and you want to avoid the plumbing of a remote valve bank. If you need less force, stepping down to the 63mm bore yields 1559 N push at 0.5 MPa; if you need maximum push, the 100mm bore offers 3927 N at 0.5 MPa. The SAIF80X125-08A is ideal for space-tight machines where running valve tubing is costly, as it switches itself from one AC220V coil signal. Remember that the 5/2 valve routes air but does not hold the load without live pressure; for true position holding, consider the SAIL (lock) or BSAI (clamp-lock) series instead. For stroke lengths of 300mm or more, ensure proper guide provisions to handle side loads.
When ordering a replacement, verify the exact configuration: an 80mm bore, 125mm stroke, 4M310-08 valve with a 1/4" valve port, PT3/8" cylinder port, AC220V voltage, terminal electrical entry, and standard PT thread. Because this unit lacks the -S magnet suffix, it will not work with AirTAC CMSE reed or DMSE electronic sensors without modification.
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 SAIF80X125-08A FAQ
The 80mm bore generates 2513 N push and 2268 N pull force at 0.5 MPa, reaching 4523 N push at 0.9 MPa. The integrated 4M310-08 valve has a 25.0 mm2 orifice with a Cv of 1.40.
No, the integrated 5/2 solenoid valve controls the cylinder directly from one AC220V coil signal. By factory default, the rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
