Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 50mm 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 SAIF32X50S-08A
The AirTAC SAIF32X50S-08A is a double-acting ISO 15552 profile cylinder featuring a pre-mounted 4M210-08 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, the integrated valve provides a Cv of 0.89 and eliminates the need for a remote valve bank. The assembly operates within a 0.15-0.8 MPa pressure range, as the built-in valve limits the cylinder's 1.0 MPa base rating. A -S magnet is included for position sensing with CMSE reed or DMSE electronic switches.
Generating 402N of push force at 0.5 MPa, this 32mm bore unit uses an O8xO5 PU tube to bridge the manifold block. By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This decentralized design requires only a single electrical signal to control the cylinder, saving panel space and tubing runs 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 (Ø32mm)

| 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 SAIF32X50S-08A Is Used
Decentralized Assembly Stations
Eliminates long air lines from a central panel by switching directly at the cylinder, streamlining large machine layouts.
Compact Clamping Jigs
Provides 402N of clamping force at 0.5 MPa in tight workspaces where mounting a separate valve is physically impossible.
Wiring Retrofits
Simplifies machine upgrades by replacing complex pneumatic tubing with a single AC220V electrical signal to the terminal coil.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X50S-08A the Right Choice?
Choose this 32mm bore when 402N of push force at 0.5 MPa is sufficient; if your application requires more thrust, stepping up to the 40mm bore yields 628N. The self-valved SAIF format outperforms a separate cylinder and remote valve in space-tight machines by consolidating airflow control directly onto the actuator. For load-holding applications, note that the 5/2 valve routes air and does not lock the piston; consider the SAIL series for mechanical locking. Replacement matching requires the 50mm stroke, 1/8" cylinder port, 1/4" valve port, AC220V terminal coil, PT thread, and the -S magnet.
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 SAIF32X50S-08A FAQ
The 32mm bore generates 402N of push force and 345N of pull force at 0.5 MPa. The integrated 4M210-08 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
No, the 5/2 solenoid valve routes air but does not lock the load. It holds its last position via internal pilot pressure, not a mechanical lock. By default, the rod retracts when energised, but it can be reconfigured to extend by repositioning the valve.
