Airtac SAIF Series Standard Cylinder with Valve SAIF80X125S-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X125S-10B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 125mm 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 SAIF80X125S-10B
The AirTAC SAIF80X125S-10B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-10 5/2 solenoid valve. This integrated manifold uses O10 x O6.5 PU tubing to connect the valve block to the cylinder body, which features a PT3/8 cylinder port and a larger PT3/8 valve port. Driven by a DC24V terminal entry coil drawing 3.0 W, it responds in 0.05 s and carries an IP65 rating. The 4M310-10 valve provides a 30.0 mm2 effective area (Cv 1.68) and switches up to 4 cycles per second.
While the bare cylinder body rates to 1.0 MPa, the operating pressure of the assembled SAIF unit is 0.15-0.8 MPa because the internal pilot valve limits the working range. In its factory setting, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The 80 mm bore generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. This -S variant includes a magnet for position sensing with AirTAC CMSE reed or DMSE electronic switches.

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 SAIF80X125S-10B Is Used
Decentralized Automation
Ideal for large assembly lines where running individual valve tubing back to a central panel is costly, as the integrated 4M310 valve switches the cylinder locally from a single DC24V signal.
Heavy Clamping Stations
Provides 2513 N of push force at 0.5 MPa for securing heavy workpieces during machining, utilizing the built-in valve to maximize floor space efficiency.
Material Handling Lifts
Suitable for compact sorting and lifting gates where the ISO 15552 mounting interface and self-contained pneumatic control simplify installation and maintenance.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X125S-10B the Right Choice?
Choose this 80 mm bore when you need heavy thrust beyond the 1559 N push force of a 63 mm bore at 0.5 MPa, but do not require the massive 3927 N output of a 100 mm cylinder. The self-valved architecture eliminates the need for a remote valve bank, drastically reducing panel space and plumbing for decentralized machine stations. Because the 5/2 valve only routes air and the end cushions merely decelerate the piston, this unit cannot hold a load without live pressure; consider an AirTAC SAIL lock cylinder if mechanical holding is required.
To replace this unit, match the 80 mm bore, 125 mm stroke, PT3/8 valve port, DC24V terminal coil, PT tapered threads, and the -S magnet option. The standard carbon steel rod handles general industrial loads, and the 125 mm stroke is well within the 1500 mm maximum standard stroke limit, meaning no side-load guide concerns apply at this length.
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 SAIF80X125S-10B FAQ
At 0.5 MPa, the 80 mm bore generates 2513 N of push force and 2268 N of pull force. The integrated 4M310-10 5/2 valve has an effective area of 30.0 mm2 (Cv 1.68) and supports a maximum frequency of 4 cycles per second.
No separate remote valve is needed. By factory default, the DC24V coil energizes to retract the rod, but this can be reconfigured to extend-when-energised by repositioning the valve. The 5/2 valve holds its position via internal pilot pressure, not a mechanical spring.
