Airtac SAIF Series Standard Cylinder with Valve SAIF100X80S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X80S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 80mm 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 SAIF100X80S-08B
The AirTAC SAIF100X80S-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. Driven by a DC24V terminal coil that consumes 3.0 W, it activates in 0.05 s or less with IP65 protection. The cylinder body features a 1/2 inch PT port, while the integrated valve utilizes a 1/4 inch port connected via a PU tube measuring O10 x O6.5.
Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. Generating 3927 N of push force at 0.5 MPa, it eliminates the need for remote plumbing. The factory setting retracts the piston rod when the coil is energised, which you can reconfigure to extend-when-energised by repositioning the valve.

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 (Ø100mm)

| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAIF100X80S-08B Is Used
Decentralized Machine Stations
Ideal for large automated lines where running separate valve tubing is costly, letting each 100mm bore cylinder control itself via a local DC24V signal.
High-Force Clamping
Provides 3927 N of push force at 0.5 MPa for heavy-duty clamping tasks in compact spaces where external valves would clutter the workspace.
Space-Constrained Automation
Suits retrofit projects or tight machine envelopes by combining a high-thrust ISO 15552 actuator and a 4M310-08 valve into one integrated package.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X80S-08B the Right Choice?
Choose this self-valved unit when your application requires high thrust (up to 3927 N at 0.5 MPa) and decentralized control across a large machine. If you need less force, stepping down to a bore 80 cylinder yields 2513 N of push force at 0.5 MPa. The SAIF100X80S-08B saves significant panel space and wiring by switching directly from one DC24V coil signal, making it superior to a separate cylinder and remote valve setup. It includes an -S magnet for position sensing with AirTAC CMSE (reed) or DMSE (electronic) switches. Remember that the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL series. To replace this unit, match the 100mm bore, 80mm stroke, 1/4 inch valve port, DC24V voltage, PT thread, terminal entry, and -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 SAIF100X80S-08B FAQ
The 100mm bore generates 3927 N of push force and 3681 N of pull force at 0.5 MPa. The built-in 4M310-08 5/2 valve provides an effective flow area of 25.0 mm2 (Cv 1.40).
Yes. The factory default retracts the rod when the DC24V coil is energised, but you can reposition the 5/2 valve on its manifold block to extend-when-energised. It holds position by pilot pressure, not a spring.
