Airtac SAIF Series Standard Cylinder with Valve SAIF80X160-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X160-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 160mm stroke and a built-in 4M310-08 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 SAIF80X160-08B
The AirTAC SAIF80X160-08B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W, it delivers 2513N of push force at 0.5 MPa. The integrated valve provides a 25.0 mm2 effective area (Cv 1.40) and switches up to 4 cycles per second. Because the cylinder body rates to 1.0 MPa but the internal piloted valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa.
This self-contained design eliminates the need for a remote valve bank, saving panel space and tubing across decentralized machine stations. The manifold connects to the cylinder using O10 x O6.5 PU tubing, while the valve itself uses a 1/4" port distinct from the cylinder's 3/8" port. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence requires it.

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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 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 SAIF80X160-08B Is Used
Decentralized Automation
Ideal for large machines with scattered stations, using a single DC24V signal to actuate the 80mm bore locally without running long pneumatic lines back to a central manifold.
High-Force Clamping
Provides 2513N of push force at 0.5 MPa for securing heavy workpieces, with the integrated 4M310 valve ensuring rapid 4Hz cycling directly on the cylinder.
Compact Wiring Retrofits
Perfect for upgrades where adding pneumatic tubing is costly, allowing a direct electrical terminal connection to drive the cylinder right at the point of use.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X160-08B the Right Choice?
Choose this 80mm bore when you need substantial thrust (2513N push at 0.5 MPa) but want to avoid the plumbing of a separate valve. If your application requires less force, stepping down to a 63mm bore yields 1559N push at 0.5 MPa; stepping up to 100mm provides 3927N. The DC24V terminal connection offers safe, low-voltage control with IP65 protection and a 0.05s activation time.
For replacements, match the 80mm bore, 160mm stroke, 3/8" cylinder port, 1/4" valve port, DC24V voltage, PT thread type, and terminal entry. Note that the built-in 5/2 valve routes air and is not a locking device; if you need true load holding without live pressure, consider the SAIL lock series. The standard carbon steel rod handles general industrial loads, and the variable air cushions safely decelerate the piston near stroke ends.
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 SAIF80X160-08B FAQ
At 0.5 MPa, this 80mm bore cylinder generates 2513N of push force and 2268N of pull force. The built-in 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and supports a maximum frequency of 4 cycles per second.
It uses a 5/2 solenoid valve powered by a DC24V terminal coil (3.0 W, IP65). By default, the factory setting retracts the rod when energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This eliminates the need for a separate remote valve.
