Airtac SAIF Series Standard Cylinder with Valve SAIF80X400S-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X400S-10A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 400mm stroke and a built-in 4M310-10 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 SAIF80X400S-10A
The AirTAC SAIF80X400S-10A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This built-in valve delivers a 30.0 mm2 effective area (Cv 1.68) and operates at 4 cycles per second. Driven by an AC220V terminal entry coil consuming 3.5 VA, it activates in 0.05 s or less. The unit includes a magnet for CMSE reed and DMSE electronic sensors. Because the valve manifold mounts directly using PU tubing (O10 x O6.5), it eliminates remote plumbing.
While the bare cylinder body rates to 1.0 MPa, the practical operating range for this assembled SAIF unit is 0.15-0.8 MPa. It generates a robust 3518 N push force at 0.7 MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 pilot valve holds its position via air pressure, not a spring, meaning it routes air but does not lock the load.

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)

| 0.7 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 SAIF80X400S-10A Is Used
Decentralized Automation
Ideal for large factory layouts where running individual valve tubing back to a central manifold is costly. The integrated 4M310-10 valve lets this 80 mm bore actuator switch itself locally via a single AC220V signal.
High-Force Clamping
Delivers 3518 N of push force at 0.7 MPa for securing heavy workpieces during machining. The 400 mm stroke provides extended reach for varied part sizes without needing external pneumatics.
Space-Tight Retrofits
Perfect for machinery upgrades where panel space is limited. The terminal entry coil and built-in manifold eliminate the need to mount a separate 5/2 valve near the cylinder.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X400S-10A the Right Choice?
Choose this 80 mm bore when you need high thrust (3518 N push at 0.7 MPa) that a 63 mm bore cannot provide (2182 N). Stepping up to a 100 mm bore yields 5497 N but demands more space. This self-valved SAIF excels in decentralized installations across large machines, replacing a separate cylinder and remote valve to save panel space and wiring. The AC220V terminal coil and PT3/8 valve port simplify electrical and pneumatic connections. For load-holding requirements, note that the 5/2 valve and air cushions only decelerate near stroke end; you must use a SAIL lock or BSAI clamp-lock cylinder for true braking. With a 400 mm stroke, ensure adequate guide support to prevent side-loading and rod damage. Replacement requires matching the 80 mm bore, 400 mm stroke, PT3/8 valve port, AC220V voltage, terminal entry, PT threads, and the -S 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 SAIF80X400S-10A FAQ
At 0.7 MPa operating pressure, this 80 mm bore cylinder generates 3518 N of push force and 2268 N of pull force. The integrated 4M310-10 5/2 valve provides an effective flow area of 30.0 mm2 (Cv 1.68) with a maximum frequency of 4 cycles per second.
No. The 5/2 valve is internally piloted and holds its last position via air pressure, not a mechanical spring. By factory default, the coil energises to retract the rod, but you can reconfigure it to extend-when-energised by repositioning the valve. It operates on AC220V with a 3.5 VA power draw.
