Airtac SAIF Series Standard Cylinder with Valve SAIF80X225S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X225S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 225mm 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 SAIF80X225S-08A
The AirTAC SAIF80X225S-08A is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40. Driven by an AC220V terminal coil drawing 3.5 VA, it switches itself from a single electrical signal, eliminating remote plumbing. While the bare cylinder rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, setting the practical working range for the assembly. It generates 2513N of push force at 0.5 MPa.
Equipped with a magnet for position sensing, it supports AirTAC CMSE reed and DMSE electronic switches. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The manifold connects using O10 x O6.5 PU tubing, and the valve port (1/4) is distinct from the cylinder port (3/8).

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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 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 SAIF80X225S-08A Is Used
Decentralized Assembly Lines
Eliminates the need for a central valve bank, letting you place independent control directly at each station across a large machine layout.
High-Force Clamping Fixtures
Delivers 2513N of push force at 0.5 MPa, ideal for securing heavy workpieces during machining operations without external plumbing.
Space-Constrained Automation
Integrates the 4M310 valve and cylinder into one envelope, saving valuable panel and floor space in dense equipment layouts.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X225S-08A the Right Choice?
Choose this 80mm bore if you need higher thrust than the 63mm class (1559N push at 0.5 MPa) but want to avoid the larger fluid demand of the 100mm bore. A self-valved SAIF beats a separate cylinder and remote valve when panel space is tight and decentralized stations reduce tubing runs across a large machine. The 225mm stroke is under the 1500mm standard maximum, but for any stroke at or above 300mm, add external guide support to prevent rod side-loading and premature seal wear.
This unit includes a -S magnet for CMSE/DMSE sensors and uses a PT tapered thread. It does not hold its load without live pressure, as the 5/2 valve routes air rather than locking it; for true load-holding, consider the SAIL lock series. To replace this SKU exactly, match the 80mm bore, 225mm stroke, 08 valve port, AC220V terminal coil, and PT thread.
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 SAIF80X225S-08A FAQ
The 80mm bore generates 2513N push and 2268N pull force at 0.5 MPa. The built-in 4M310-08 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a max frequency of 4 cycles per second.
It uses a 5/2 solenoid valve that holds position by pilot pressure, not a spring. The factory setting retracts the rod when the AC220V terminal coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve, removing the need for a separate remote valve.
