Airtac SAIF Series Standard Cylinder with Valve SAIF50X80-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X80-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm 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 SAIF50X80-08A
The AirTAC SAIF50X80-08A is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89. Driven by an AC220V coil with a terminal electrical entry, it consumes 3.5 VA and responds in 0.05 s. While the cylinder body rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, establishing the practical working range for the assembly. It delivers 982 N of push force at 0.5 MPa.
By mounting the valve directly via a manifold block and short PU tubing (O8 x O5), this unit switches itself from one coil signal. This eliminates remote plumbing, saves panel space, and is ideal for decentralized stations across large machines. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. The cylinder port is PT1/4, which differs from the valve port code 08.

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 (Ø50mm)

|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAIF50X80-08A Is Used
Decentralized Assembly Stations
Eliminates remote valve plumbing by driving the actuator directly from one AC220V signal, saving panel space on large multi-station machines.
Space-Constrained Machinery
The integrated 4M210-08 valve manifold shortens the overall footprint while delivering 982 N of push force at 0.5 MPa.
Retrofit Automation
Ideal for upgrading existing lines where routing new pneumatic tubing back to a central valve bank is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X80-08A the Right Choice?
Choose this 50mm bore if your application requires around 982 N of push force at 0.5 MPa. If you need less force, stepping down to a 40mm bore yields 628 N; if you need more, a 63mm bore provides 1559 N. The SAIF50X80-08A is optimal when a self-valved cylinder beats running separate valve tubing to a remote island, saving wiring and space. Since the built-in 5/2 valve routes air and holds position via pilot pressure, it does not lock the load mechanically—use AirTAC SAIL for locking needs. To replace this unit, match the 50mm bore, 80mm stroke, 08 valve port, AC220V terminal coil, PT thread, and no magnet (-S).
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 SAIF50X80-08A FAQ
The 50mm bore generates 982 N of push force and 825 N of pull force at 0.5 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice with a Cv of 0.89.
The integrated 5/2 valve switches the cylinder from one AC220V coil signal. By default, the rod retracts when energised but can be reconfigured to extend. The valve routes air and does not lock the load mechanically without live pressure.
