Airtac SAIF Series Standard Cylinder with Valve SAIF40X160S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X160S-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 160mm 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 SAIF40X160S-08A
The AirTAC SAIF40X160S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. Equipped with a magnet for position sensing, it works seamlessly with AirTAC CMSE reed and DMSE electronic switches. The integrated valve provides an effective flow area of 16.0 mm2 (Cv 0.89) and operates at a maximum frequency of 5 cycles per second. Driven by an AC220V terminal connection coil drawing 3.5 VA, it activates in 0.05 seconds or less.
Because the cylinder body rates to 1.0 MPa but the integrated 4M210 valve limits pressure to 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The manifold links the valve to the cylinder using O8 x O5 PU tubing. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. By switching itself from one coil signal, it eliminates remote plumbing, saves panel space, and suits decentralized stations perfectly.

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 (Ø40mm)

|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAIF40X160S-08A Is Used
Decentralized Assembly Stations
Ideal for large machines where running individual valve tubing back to a central island is costly, allowing local control via a single AC220V signal.
Compact Clamping Fixtures
The integrated valve manifold saves valuable envelope space on tight machining fixtures while delivering 528N of pull force for secure workholding.
Sensor-Driven Handling
The -S magnet pairs with DMSE solid-state sensors to confirm rod position in automated ejection gates operating up to 5 cycles per second.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X160S-08A the Right Choice?
Choose this 40mm bore when you need 628N of push force or 528N of pull force at 0.5 MPa. If your application requires higher thrust, stepping up to the 50mm bore yields 982N push force at 0.5 MPa. The self-valved SAIF design beats a separate cylinder and remote valve in space-tight machines by cutting out interconnecting tubing and central manifold blocks. Since the stroke is 160mm, ensure adequate guidance to prevent excessive side loads on the rod.
For replacements, match the 40mm bore, 160mm stroke, 1/4" cylinder port, PT tapered threads, 08 valve port code, AC220V voltage, terminal entry, and the -S magnet option. Remember that the 5/2 valve routes air but does not lock the load; if you need true holding force without live pressure, consider the SAIL lock series instead.
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 SAIF40X160S-08A FAQ
At 0.5 MPa it provides 628N push and 528N pull force. While the cylinder body rates to 1.0 MPa, the built-in 4M210 valve limits the practical operating pressure to 0.15-0.8 MPa.
By default, the factory setting retracts the rod when the AC220V coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the 5/2 valve on the manifold block.
