Airtac SAIF Series Standard Cylinder with Valve SAIF32X225S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X225S-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 225mm 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 SAIF32X225S-08B
The AirTAC SAIF32X225S-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W, it delivers 402N push force at 0.5 MPa. The integrated manifold uses an O8xO5 PU tube to bridge the 1/4" valve port to the 1/8" cylinder port. Because the built-in valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa, despite the bare cylinder rating to 1.0 MPa.
This unit controls itself from one coil signal, eliminating remote plumbing and saving panel space for decentralized stations. By factory default, the piston rod retracts when the coil is energised; you can reconfigure it to extend-when-energised by repositioning the valve. The -S magnet supports CMSE reed and DMSE electronic sensors for position feedback. It features a carbon steel rod and PT tapered threads.

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 SAIF32X225S-08B Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve island on compact machines, driving the 402N stroke directly from a single DC24V signal.
Space-Tight Diverters
The integrated 4M210 valve manifold saves panel space while providing 5/2 control for diverting packages at 0.15-0.8 MPa.
Retrofit Positioning
Ideal for upgrading existing ISO 15552 lines where routing new pneumatic tubing back to a central control cabinet is too costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X225S-08B the Right Choice?
Choose the 32mm bore when 402N at 0.5 MPa is sufficient; stepping up to the 40mm bore yields 628N if your load requires more force. A self-valved SAIF beats a separate cylinder and remote valve in space-tight machines or retrofits where running valve tubing is costly. The 4M210 valve offers a 16.0 mm2 effective area (Cv 0.89) and cycles up to 5 times per second. This DC24V terminal entry coil responds in 0.05 s with IP65 protection. Remember, the 5/2 valve routes air but does not lock the load—use a SAIL lock cylinder if you need mid-stroke holding. For this 225 mm stroke, ensure adequate guide support to prevent side-load damage.
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 SAIF32X225S-08B FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice with a Cv of 0.89, supporting cylinder speeds of 30-800 mm/s.
The DC24V terminal coil energizes the 5/2 valve, which by factory default retracts the rod. It can be repositioned to extend-when-energised. The valve routes air but does not lock the load without live pressure; for holding, use a SAIL lock cylinder.
