Airtac SAIF Series Standard Cylinder with Valve SAIF32X125-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X125-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 125mm 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 SAIF32X125-08A
The AirTAC SAIF32X125-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. Delivering a 0.5 MPa push force of 402 N, it uses a carbon steel rod and PT1/4 cylinder ports. The integrated valve offers a 16.0 mm2 effective area (Cv 0.89) and operates at 5 cycles/sec. Because the manifold routes air via an O8 x O5 PU tube, the valve port differs from the cylinder port, eliminating separate remote plumbing.
This assembly is driven by an AC220V terminal coil drawing 3.5 VA, featuring IP65 protection and a 0.05 s response time. While the bare cylinder rates to 1.0 MPa, the integrated valve limits the practical SAIF operating pressure to 0.15-0.8 MPa. By default, the factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised if needed.

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)

|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 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 SAIF32X125-08A Is Used
Decentralized Stations
Ideal for large machines with distributed stations, eliminating long tubing runs by switching the cylinder directly from the AC220V terminal coil.
Compact Clamping
Provides 402 N of push force at 0.5 MPa in tight spaces where a separate valve manifold would exceed the available machine envelope.
Retrofit Upgrades
Perfect for upgrading existing ISO 15552 interchangeable setups where adding a remote valve would require extensive rewiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X125-08A the Right Choice?
Choose the SAIF32X125-08A for decentralized stations where running valve tubing is costly, as one coil signal switches the cylinder directly, saving panel space. If your application requires greater thrust, step up to the 40 mm bore, which provides 628 N of push force at 0.5 MPa. Keep in mind that the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock cylinder.
When specifying a replacement, verify the 32 mm bore, 125 mm stroke, 1/4 inch valve port, AC220V terminal coil, and PT tapered threads. Since the stroke is 125 mm, ensure adequate guiding to prevent side-load wear on the extruded aluminum profile barrel.
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 SAIF32X125-08A FAQ
The 32 mm bore generates 402 N of push force at 0.5 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice with a Cv of 0.89, supporting a maximum frequency of 5 cycles per second.
No, the 5/2 valve routes air but does not lock the load; for holding, use a SAIL cylinder. By factory default, the rod retracts when the AC220V coil is energised, but you can reposition the valve to extend-when-energised.
