Airtac SAIF Series Standard Cylinder with Valve SAIF100X50S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X50S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 50mm 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 SAIF100X50S-08B
The AirTAC SAIF100X50S-08B is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a PT1/4 valve port, DC24V terminal electrical entry, and a -S magnet for precise position tracking using AirTAC CMSE reed or DMSE electronic sensors. The built-in valve provides a 25.0 mm2 effective area (Cv 1.40) and switches at up to 4 cycles per second.
Because the 5/2 valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa, despite the bare cylinder rating of 1.0 MPa. In its factory setting, the piston rod retracts when the coil is energized, but you can reposition the valve to extend-when-energized. This self-contained design eliminates remote plumbing, using an O10 x O6.5 PU tube manifold to drive the 100mm bore, which generates 3927N of push force at 0.5 MPa.

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 SAIF100X50S-08B Is Used
Decentralized Automation
Perfect for large machines with scattered stations, eliminating long air tubing runs by switching locally via the integrated 4M310-08 valve.
Heavy Clamping
Provides 3927N of push force at 0.5 MPa for securing heavy workpieces, using the DC24V coil to trigger high-force movements on demand.
Retrofit Upgrades
Ideal for upgrading existing ISO 15552 setups where panel space is full, adding self-switching logic without requiring a separate remote valve island.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X50S-08B the Right Choice?
Choose this 100mm bore model when your application requires substantial thrust, such as 3927N push or 3681N pull at 0.5 MPa. If your force requirements are lower, stepping down to the 80mm bore yields 2513N push force while saving envelope space. The SAIF100X50S-08B is optimal for decentralized stations where running separate valve tubing and wiring back to a main panel is costly or impractical. It switches itself from one DC24V coil signal, drawing 3.0W with IP65 protection and a 0.05s response time.
When specifying a replacement, confirm the 50mm stroke, 1/2 cylinder port, PT1/4 valve port, DC24V terminal coil, and the -S magnet. Note that the built-in valve routes air and the variable air cushions only decelerate near stroke end; neither holds the load mechanically without live pressure. For positive load holding, consider an AirTAC SAIL lock cylinder instead.
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 SAIF100X50S-08B FAQ
At 0.5 MPa, this 100mm bore cylinder generates 3927N of push force and 3681N of pull force. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) to handle the required air volume.
No, the SAIF100X50S-08B has a built-in 4M310 valve driven by a DC24V terminal coil. By factory default, energizing the coil retracts the rod, but the valve can be repositioned to extend-when-energized.
