Airtac SAIF Series Standard Cylinder with Valve SAIF32X50-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X50-08B 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 SAIF32X50-08B
The AirTAC SAIF32X50-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by a DC24V terminal connection coil consuming 3.0 W, the assembly switches itself directly from one electrical signal. The integrated valve provides an effective area of 16.0 mm2 (Cv 0.89) and operates at 5 cycles per second. Because the cylinder body rates to 1.0 MPa but the built-in valve limits pressure to 0.15-0.8 MPa, the practical working range for this valved unit is 0.15-0.8 MPa.
This 32mm bore generates 402N of push force at 0.5 MPa and pulls 345N. The manifold links the valve to the cylinder using O8 x O5 PU tubing, meaning the 1/4" valve port differs from the cylinder's PT1/8 port. Factory-set to retract the carbon steel rod when energised, the valve can be repositioned to extend-when-energised. This decentralized design eliminates remote plumbing and saves panel space.

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 SAIF32X50-08B Is Used
Decentralized Stations
Eliminates the need for a remote valve island, reducing tubing runs across large machine footprints.
Compact Assembly
Fits into tight mechanical spaces where separate valve plumbing would be impossible or too bulky.
Retrofit Automation
Simplifies machine upgrades by driving the cylinder directly from a local DC24V terminal signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X50-08B the Right Choice?
Choose this self-valved SAIF32X50-08B for decentralized stations where routing separate valve tubing is costly. If your application requires greater thrust, stepping up to the 40mm bore yields 628N push force at 0.5 MPa. The compact 50mm stroke is ideal for tight spaces, but remember the 5/2 valve routes air and does not hold the load without live pressure; for position holding, consider the SAIL lock cylinder.
When specifying a replacement, verify the 32mm bore, 50mm stroke, 1/4" valve port, DC24V voltage, terminal entry, PT thread, and the absence of a magnet (-S). The base cylinder is dimensionally interchangeable per ISO 15552. Operating speed ranges from 30-800 mm/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 SAIF32X50-08B FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The maximum push force reaches 724N at 0.9 MPa.
No, the integrated 4M210-08 5/2 valve controls the cylinder directly from a DC24V signal. Factory-set to retract when energised, it can be repositioned to extend-when-energised.
