Airtac SAIF Series Standard Cylinder with Valve SAIF80X350-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X350-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 350mm 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 SAIF80X350-08A
The AirTAC SAIF80X350-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. Equipped with a 1/4" valve port and PT3/8" cylinder port, the integrated valve delivers a Cv of 1.40 and operates at a maximum frequency of 4 cycles per second. Driven by an AC220V terminal entry coil drawing 3.5 VA, it activates in 0.05 seconds. While the base cylinder rates to 1.0 MPa, the practical operating range for this valved unit is 0.15-0.8 MPa. The manifold connects to the cylinder via O10xO6.5 PU tubing, and the standard carbon steel rod provides 2513N of push force at 0.5 MPa.
By default, the factory setting retracts the piston rod when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. This self-switching design eliminates the need for a separate remote valve, reducing tubing and panel space for decentralized installations across large machines. It features variable air cushions at both ends to decelerate the load near stroke limits, though it relies on live pressure and does not hold position mechanically.

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 SAIF80X350-08A Is Used
Decentralized Automation
Ideal for large machine layouts where individual cylinder control eliminates long pneumatic runs from a central valve bank.
High-Force Clamping
Provides 2513N of push force at 0.5 MPa for securing heavy workpieces during machining or assembly operations.
Retrofit Upgrades
Simplifies machine upgrades by integrating the valve directly on the cylinder, avoiding the need to modify existing panel enclosures.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X350-08A the Right Choice?
Choose this 80mm bore when an application requires higher thrust than the 63mm bore (which provides 1559N push at 0.5 MPa) but does not need the full 3927N output of the 100mm variant. The integrated 4M310 valve makes the SAIF80X350-08A ideal for decentralized stations where running separate valve tubing is costly or space-prohibitive. The AC220V terminal connection suits standard industrial power, and the PT3/8" cylinder port matches the bore's flow requirements. For load-holding applications, note that the 5/2 valve routes air and is not a lock; consider the SAIL series for pneumatic locking needs. Because the 350mm stroke exceeds 300mm, ensure adequate guiding to prevent excessive side-load on the rod. Replacement requires matching the 80mm bore, 350mm stroke, 08 valve port, AC220V voltage, terminal entry, PT thread, and no 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 SAIF80X350-08A FAQ
The 80mm bore generates 2513N of push force and 2268N of pull force at 0.5 MPa. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) and supports a max frequency of 4 cycles per second.
No, the built-in 5/2 solenoid valve routes air to hold position only with live pressure; it is not a mechanical lock. The factory setting retracts the rod when the AC220V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
