Airtac SAIF Series Standard Cylinder with Valve SAIF80X175-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X175-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 175mm 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 SAIF80X175-08A
The AirTAC SAIF80X175-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve provides an effective flow rate of Cv 1.40 via a 1/4" valve port, driving the 80mm bore which delivers 2513N of push force at 0.5 MPa. Equipped with a carbon steel piston rod and PT tapered threads, it operates on an AC220V coil with a standard terminal electrical entry, consuming 3.5 VA and responding in 0.05s.
Because the manifold relies on the 4M310 valve, the practical working pressure for the assembled SAIF unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa. The factory default setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised if the motion logic requires it. This self-switching design eliminates remote plumbing, saving panel space and making it ideal for decentralized stations across large machines.

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)

| 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 SAIF80X175-08A Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve island on large machines by switching the 80mm bore directly from a local AC220V terminal signal.
High-Force Clamping Fixtures
Delivers 2513N of push force at 0.5 MPa for secure workholding, with the built-in 4M310 valve ensuring fast 0.05s response times.
Space-Constrained Retrofits
Ideal for upgrading older machines where routing new pneumatic tubing to a separate panel is costly, as the valve and manifold mount directly on the profile barrel.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X175-08A the Right Choice?
Choose this 80mm bore when a 63mm neighbour (1402N pull at 0.5 MPa) is insufficient, or step down if 2513N of push force exceeds your load requirements. The SAIF80X175-08A is selected when a self-valved cylinder beats running separate valve tubing, as the integrated 4M310 valve handles switching directly from one AC220V terminal signal. Remember that the 5/2 valve routes air but does not lock the load; for true position holding under lost pressure, consider the SAIL lock or BSAI clamp-lock series instead. When ordering a replacement, verify the 175mm stroke, 3/8" cylinder port, 1/4" valve port, AC220V voltage, terminal entry, and standard PT threads.
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 SAIF80X175-08A FAQ
The 80mm bore generates 2513N of push force and 2268N of pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve provides an effective flow area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
It requires only one AC220V coil signal to operate. The factory setting retracts the rod when energised, but you can reconfigure the valve to extend-when-energised. The 5/2 valve routes air but does not hold the load without live pressure; it is not a mechanical lock.
