Airtac SAIF Series Standard Cylinder with Valve SAIF100X350S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X350S-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 350mm 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 SAIF100X350S-08A
The AirTAC SAIF100X350S-08A is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, fitted with a built-in 4M310-08 5/2 solenoid valve delivering a Cv of 1.40. Driven by an AC220V terminal coil drawing 3.5 VA, it integrates switching directly on the manifold. The cylinder port is PT1/2, while the valve features a 1/4 port connected via O10 x O6.5 PU tubing. A magnet (-S) is included for CMSE reed and DMSE electronic sensors.
Because the cylinder body rates to 1.0 MPa but the 4M310 valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. It delivers 3927N of push force at 0.5 MPa and reaches a maximum of 801 kgf at 1.0 MPa. Factory set to retract when energised, the valve can be repositioned to extend on signal, eliminating remote plumbing for decentralized stations.

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 SAIF100X350S-08A Is Used
Decentralized Automation
Ideal for large machines with distributed stations, using the built-in 4M310 valve to eliminate long tubing runs from a central panel.
High-Force Clamping
Provides 3927N of push force at 0.5 MPa directly at the work point, perfect for heavy-duty clamping without external valve lag.
Retrofit & Upgrade
Simplifies machine upgrades where adding a new valve island is costly, dropping a self-switching cylinder directly into an ISO 15552 footprint.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X350S-08A the Right Choice?
Choose this self-valved SAIF100X350S-08A for high-force decentralized tasks requiring 3927N push at 0.5 MPa. If an application needs less force, stepping down to the 80mm bore yields 2513N push at 0.5 MPa. The integrated 4M310 valve and AC220V terminal coil remove the need for a separate panel valve, cutting tubing and wiring. For stroke lengths of 350mm, ensure external guide rails are used to manage side loads and prevent rod binding.
When specifying replacements, match the 100mm bore, 350mm stroke, 1/4 valve port, AC220V voltage, terminal entry, PT thread, and -S magnet. Remember that the 5/2 valve routes air but does not lock the load mechanically; for true position holding under pressure loss, select an AirTAC SAIL pneumatic 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 SAIF100X350S-08A FAQ
The 100mm bore generates 3927N push and 3681N pull force at 0.5 MPa, reaching 801 kgf max at 1.0 MPa. The built-in 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 separate remote valve is needed; one AC220V coil signal drives the cylinder. By factory default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The practical operating pressure is 0.15-0.8 MPa.
