Airtac SAIF Series Standard Cylinder with Valve SAIF80X175-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X175-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 175mm 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 SAIF80X175-08B
The AirTAC SAIF80X175-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a maximum frequency of 4 cycles per second. Driven by a DC24V terminal entry coil consuming 3.0 W, it activates in 0.05 seconds. The cylinder body features a 3/8 inch PT port, while the integrated valve utilizes a 1/4 inch port, connecting internally via a PU tube. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembly, even though the bare cylinder rates to 1.0 MPa. At 0.5 MPa, this 80mm bore generates 2513N of push force and 2268N of pull force.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design eliminates the need for remote plumbing, saving panel space and making it ideal for decentralized stations across large machines. The standard carbon steel rod and variable air cushions at both ends ensure robust, decelerated operation. Note that the 5/2 valve routes air and does not lock the load; for position holding, consider the SAIL series.

| 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 SAIF80X175-08B Is Used
Decentralized Automation
Ideal for large machine layouts where running individual valve lines is costly, allowing each station to control itself via a single DC24V signal.
High-Force Clamping
Provides 2513N of push force at 0.5 MPa for securing heavy workpieces during machining, without needing an external valve bank.
Compact Assembly Lines
Saves valuable panel and footprint space by integrating the 5/2 valve directly onto the cylinder body, streamlining the pneumatic architecture.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X175-08B the Right Choice?
Select this 80mm bore when your application requires substantial thrust, such as the 2513N push force at 0.5 MPa. If you need less force, stepping down to the 63mm bore yields 1559N at 0.5 MPa, while moving up to the 100mm bore provides 3927N at 0.5 MPa. The integrated 4M310-08 valve with its 1.40 Cv flow capacity easily handles the air volume required for this bore size. Choose this self-valved SAIF configuration over a separate cylinder and remote valve when you want to minimize wiring and tubing in space-constrained machines. When ordering a replacement, verify the 175mm stroke, 3/8 inch cylinder port, 1/4 inch valve port, DC24V voltage, terminal entry, PT thread, and the absence of a magnet (-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 SAIF80X175-08B FAQ
The 80mm bore generates 2513N push and 2268N pull force at 0.5 MPa. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) and a max frequency of 4 cycles per second.
The factory setting retracts the rod when the coil is energised. This can be reconfigured to extend-when-energised by repositioning the valve. The 5/2 valve holds its position via pilot pressure, not a spring, so no separate remote valve is needed.
