Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 500mm 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 SAIF32X500S-08B
The AirTAC SAIF32X500S-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve. Delivering a Cv of 0.89 and a 16.0 mm2 orifice, the integrated valve manifold switches the cylinder directly from a single DC24V terminal entry coil signal. The cylinder body features an extruded aluminum barrel with a carbon steel piston rod, and the -S magnet option enables position tracking via AirTAC CMSE reed and DMSE electronic sensors. Because the cylinder rates to 1.0 MPa but the built-in valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled SAIF unit is 0.15-0.8 MPa.
By eliminating the need for a remote valve panel, this self-contained actuator saves tubing and panel space, making it ideal for decentralized machine stations. The valve manifold connects to the cylinder via O8 x O5 PU tubing, and the valve port (1/4 inch) differs from the cylinder port (1/8 inch). Factory set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your sequence demands it. The DC24V coil draws 3.0 W, features IP65 protection, and responds in 0.05 s or less.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF32X500S-08B Is Used
Decentralized Assembly Stations
Eliminates remote valve plumbing, allowing independent cylinder control across large automated machinery layouts.
Space-Constrained Diverters
The integrated 4M210 valve and manifold block save critical panel space on tight conveyor sorting frames.
Retrofit Automation
Ideal for upgrading older machines where running new pneumatic tubing back to a central valve island is impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08B the Right Choice?
Choose this 32mm bore when you need 402N of push force at 0.5 MPa; if your mechanism requires greater thrust, step up to the 40mm bore which provides 628N at the same pressure. The 500mm stroke on this model demands rigid guidance to prevent side-loading damage to the extruded aluminum profile barrel and carbon steel rod. The SAIF format is superior to a standard cylinder plus remote valve when wiring and plumbing costs run high, as the 5/2 valve is mounted directly on the cylinder via a manifold block. Note that the 5/2 valve routes air and does not hold the load without live pressure; for true locking requirements, select the SAIL series instead. When ordering replacements, verify the 500mm stroke, 1/4 inch valve port, DC24V terminal coil, PT threaded ports, and the -S magnet option.
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 SAIF32X500S-08B FAQ
The 32mm bore generates 402N of push force and 345N of pull force at 0.5 MPa. The built-in 4M210-08 valve provides a 16.0 mm2 effective area (Cv 0.89) and can cycle up to 5 times per second.
It features a built-in 4M210 5/2 valve mounted on a manifold block, driven by a DC24V terminal coil. Factory set to retract when energised, the valve can be repositioned to extend-when-energised, giving you full directional control from a single electrical signal.
