Airtac SAIF Series Standard Cylinder with Valve SAIF100X150S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X150S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 150mm 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 SAIF100X150S-08B
The AirTAC SAIF100X150S-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 and a robust 3927N push force at 0.5 MPa, it handles heavy loads with ease. The unit operates on DC24V power via a terminal electrical entry, consuming just 3.0 W with an IP65 rating and a rapid 0.05s activation time. A pre-installed magnet (-S) supports CMSE reed and DMSE solid-state sensors for precise end-of-stroke detection.
Because the integrated 4M310 valve manages airflow directly, this self-switching assembly eliminates the need for remote valve plumbing, saving substantial panel space in decentralized machine layouts. The manifold connects to the cylinder using O10 x O6.5 PU tubing, while the valve features a 1/4" port and the main cylinder body uses a 1/2" port. Although the cylinder body rates to 1.0 MPa, the practical operating range for this valved unit is 0.15-0.8 MPa. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your cycle logic requires it.

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 SAIF100X150S-08B Is Used
Decentralized Automation
Eliminates remote valve banks by driving heavy 100mm bore motion directly from a single DC24V signal at the station.
High-Force Assembly
Delivers up to 3927N of push force for heavy-duty pressing and clamping tasks without needing external plumbing.
Retrofits & Upgrades
Ideal for machine upgrades where adding centralized air manifolds is costly, utilizing built-in 5/2 valve control instead.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X150S-08B the Right Choice?
Choose this 100mm bore SAIF when you need maximum thrust (up to 3927N push at 0.5 MPa) in a space-constrained, decentralized layout where running separate valve tubing is impractical. If your application requires less force, stepping down to the 80mm bore yields 2513N push at 0.5 MPa while saving physical envelope. Conversely, if you need even higher flow than the 4M310-08 provides, verify whether a larger port configuration suits your cycle times. Remember that the 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, select a SAIL lock or BSAI clamp-lock cylinder instead. For replacements, verify the 150mm stroke, 1/2" cylinder port, 4M310-08 valve, DC24V terminal coil, PT threads, 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 SAIF100X150S-08B FAQ
The 100mm bore cylinder provides 3927N push and 3681N pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) with a max frequency of 4 cycles/sec.
No, the 5/2 valve routes air but does not lock the rod mechanically; for load-holding use a SAIL cylinder. The DC24V terminal coil draws 3.0W, and by factory default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
