Airtac SAIF Series Standard Cylinder with Valve SAIF100X150S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X150S-08A 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-08A
The AirTAC SAIF100X150S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve delivers a 1.40 Cv flow rate and eliminates the need for a remote valve, drastically reducing panel space and plumbing for decentralized machine stations. Equipped with a magnet for position sensing, it supports AirTAC CMSE reed and DMSE electronic sensors. The unit is supplied with an AC220V terminal coil consuming 3.5 VA, IP65 protection, and a 0.05s response time.
While the bare cylinder body rates to 1.0 MPa, the practical operating pressure for this valved assembly is 0.15-0.8 MPa. It delivers 3927N of push force at 0.5 MPa, scaling up to 7068N at 0.9 MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The manifold connects to the cylinder via PU tubing, and note the valve port is 1/4" while the cylinder port is 1/2".

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-08A Is Used
Decentralized Assembly Stations
Ideal for large factory layouts where installing individual valve manifolds is impractical. The integrated 4M310 valve lets this 100mm cylinder operate independently from a single AC220V signal.
High-Force Clamping
Provides 7068N of push force at 0.9 MPa for heavy-duty clamping and holding operations, eliminating the need for external plumbing while maintaining ISO 15552 mounting interchangeability.
Space-Constrained Retrofits
Perfect for machine upgrades where panel space is limited. The built-in valve and terminal entry save valuable real estate while delivering a 1.40 Cv flow directly to the 100mm bore.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X150S-08A the Right Choice?
Choose this 100mm bore when your application requires high thrust, such as 7068N at 0.9 MPa. If you need less force, stepping down to a 63mm bore yields 1559N at 0.5 MPa, which may save space and air consumption. The SAIF100X150S-08A excels in decentralized installations where routing separate valve tubing back to a manifold is costly or impractical. It switches itself from one AC220V coil signal, meaning less wiring and faster deployment across large machines.
When ordering a replacement, verify the 150mm stroke, 1/2" cylinder port, 1/4" valve port, AC220V terminal coil, PT threaded connections, and the -S magnet option. The 4M310 valve is internally piloted and holds its last position pneumatically, but it does not lock the load without live pressure; for true load-holding, consider the SAIL or BSAI series. Since the stroke is 150mm, ensure adequate guiding to prevent excessive side-loading on the rod.
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-08A FAQ
The 100mm bore provides 3927N push force at 0.5 MPa and 7068N at 0.9 MPa. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and a max frequency of 4 cycles/sec.
No, the 5/2 valve routes air and holds its last position via internal pilot pressure, but it is not a mechanical lock. The factory setting retracts the rod when the AC220V coil is energised, but it can be repositioned to extend-when-energised. For true load holding, use a SAIL lock cylinder.
