Airtac SAIF Series Standard Cylinder with Valve SAIF40X160-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X160-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 160mm stroke and a built-in 4M210-06 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 SAIF40X160-06A
The AirTAC SAIF40X160-06A is a double-acting profile cylinder with an integrated 4M210-06 5/2 solenoid valve, delivering a 628N push force at 0.5 MPa. Driven by an AC220V terminal coil consuming 3.5 VA, it eliminates the need for a remote valve bank. The built-in valve features a 1/8" port with a Cv of 0.78, using an O8 x O5 PU tube to connect the manifold block to the cylinder body.
Because the 4M210 valve operates at 0.15-0.8 MPa, the practical working pressure of this assembled unit is 0.15-0.8 MPa, even though the ISO 15552 interchangeable aluminum barrel rates up to 1.0 MPa. By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This self-switching design saves panel space and tubing, making it ideal for decentralized machine stations.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF40X160-06A Is Used
Decentralized Assembly Stations
Eliminates remote valve plumbing by self-switching via the integrated 4M210 valve, freeing up control panel space in large factories.
Space-Constrained Machinery
The compact profile cylinder and built-in manifold block reduce overall envelope dimensions where running external tubing is difficult.
Wiring Retrofits
Simplifies electrical upgrades by using a single AC220V terminal coil connection to drive the entire double-acting actuator locally.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X160-06A the Right Choice?
Choose this 40mm bore if a 32mm bore (402N push at 0.5 MPa) is too weak, but a 50mm bore (982N push at 0.5 MPa) is oversized. The SAIF40X160-06A is optimal when you want to avoid plumbing a separate cylinder and remote valve, as one AC220V terminal connection drives the entire assembly. The 160mm stroke falls well within the 1200mm standard limit, but since it exceeds 300mm, ensure you provide adequate guide support to prevent excessive side-loading on the rod.
Remember that the built-in 5/2 valve routes air and holds its position via internal pilot pressure, but it is not a lock; if you need true load-holding, consider the SAIL series. The cylinder port is PT1/8, while the valve port code is 06. To replace this unit, match the 40mm bore, 160mm stroke, 4M210-06 valve, AC220V voltage, terminal entry, PT thread, and standard carbon steel rod without a magnet.
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 SAIF40X160-06A FAQ
The 40mm bore generates 628N push and 528N pull at 0.5 MPa. The integrated 4M210-06 valve has a 14.0 mm2 orifice with a Cv of 0.78, cycling up to 5 times per second.
No, it has a built-in 5/2 valve. By default, energising the AC220V coil retracts the rod, but you can reposition the valve to extend-when-energised. It holds position via internal pilot pressure, not a spring.
