Airtac SAIF Series Standard Cylinder with Valve SAIF80X75-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X75-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 75mm 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 SAIF80X75-08A
The AirTAC SAIF80X75-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve provides an effective flow area of 25.0 mm2 (Cv 1.40) and mounts directly via a manifold block using O10 x O6.5 PU tubing. Driven by an AC220V terminal connection coil drawing 3.5 VA, it activates in 0.05 s or less with an IP65 rating. While the bare cylinder rates to 1.0 MPa, the integrated valve limits the practical operating pressure to 0.15-0.8 MPa.
Delivering 2513N of push force at 0.5 MPa and up to 4523N at 0.9 MPa, this unit eliminates the need for a separate remote valve. The factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised by simply repositioning the valve. It is a self-switching solution ideal for decentralized stations across large machines.

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)

| 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 SAIF80X75-08A Is Used
Decentralized Assembly Lines
Ideal for large-scale automated machinery where running individual valve tubing back to a central panel is costly and complex.
High-Force Clamping
Provides robust 4523N push force at 0.9 MPa for holding heavy workpieces securely during machining or welding operations.
Space-Constrained Retrofitting
The integrated valve manifold saves valuable real estate on tight machine frames, delivering self-switched actuation without external plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X75-08A the Right Choice?
Choose this 80mm bore model when your application requires substantial thrust that a 63mm bore (1559N push at 0.5 MPa) cannot provide, but a 100mm unit is excessive. The 75mm stroke is well within the 1500mm maximum standard, making it highly responsive for shorter cycles. The integrated 4M310-08 valve handles up to 4 cycles per second, matching the 30-800 mm/s speed range of the cylinder.
This SAIF assembly is selected over a plain SAI cylinder with remote plumbing when you need to minimize panel space and tubing runs. The AC220V terminal coil offers straightforward wiring, and the valve port is 1/4" (code 08) while the cylinder port is 3/8". Note that the 5/2 valve routes air but does not hold the load without live pressure; for true mechanical locking, consider the SAIL series. When ordering a replacement, verify the 80mm bore, 75mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT threads, 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 SAIF80X75-08A FAQ
The 80mm bore generates 2513N push force at 0.5 MPa and 4523N at 0.9 MPa. The built-in 4M310-08 valve provides an effective flow area of 25.0 mm2 (Cv 1.40).
No separate remote valve is needed; one AC220V coil signal drives the cylinder. The factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised.
