Airtac SAIF Series Standard Cylinder with Valve SAIF100X400-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X400-10B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 400mm stroke and a built-in 4M310-10 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 SAIF100X400-10B
The AirTAC SAIF100X400-10B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry consuming 3.0 W, a PT3/8 cylinder port, and a 3/8 valve port. The built-in valve provides an effective area of 30.0 mm2 (Cv 1.68) and handles up to 4 cycles per second. Because the valve manifold operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the bare cylinder rates to 1.0 MPa. The manifold bridging the valve and cylinder uses a PU tube measuring O10 x O6.5.
At 0.5 MPa this 100 mm bore generates 3927 N of push force and 3681 N of pull force, peaking at 801 kgf under 1.0 MPa. The unit switches itself from one coil signal, eliminating remote plumbing and saving panel space for decentralized machine stations. From the factory, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence requires it. The standard carbon steel rod and variable air cushions at both ends handle the 400 mm travel reliably.

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)

| 0.7 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 SAIF100X400-10B Is Used
Decentralized Automation
Eliminates the need for a remote valve bank, allowing independent heavy-duty actuation at distant machine zones using only a DC24V signal.
Heavy Clamping Stations
Provides 3927 N of push force at 0.5 MPa directly at the workpiece, simplifying tooling layouts by integrating the 4M310 valve.
Retrofit Upgrades
Ideal for upgrading existing ISO 15552 installations where routing new pneumatic tubing to a central panel is impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X400-10B the Right Choice?
Choose this 100 mm bore when you need heavy thrust in a compact, self-switching format; stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N. The 400 mm stroke is well within the 1500 mm maximum standard travel for this bore, but at this length you should use a guide to prevent excessive side-loading on the rod seals. The integrated 4M310 valve removes the need for a separate remote valve, making it highly effective for decentralized stations where running air tubing is costly. The DC24V terminal coil draws 3.0 W with IP65 protection and a 0.05 s response time.
Remember that the 5/2 valve routes air but does not lock the load; if you need true position holding without live pressure, consider an AirTAC SAIL lock cylinder or BSAI clamp-lock instead. For exact replacement, match the 100 mm bore, 400 mm stroke, 3/8 valve port, PT3/8 cylinder port, DC24V voltage, terminal entry, PT thread, and no magnet (-S omitted). Without the -S suffix, this unit cannot host CMSE reed or DMSE electronic sensors.
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 SAIF100X400-10B FAQ
At 0.5 MPa, this 100 mm bore cylinder outputs 3927 N of push force and 3681 N of pull force. The integrated 4M310-10 valve has a 3/8 port with a 30.0 mm2 effective area (Cv 1.68).
No, the 5/2 valve routes air but does not function as a brake or lock. The factory setting retracts the rod when the DC24V coil is energised, but it can be reconfigured to extend-when-energised. For load holding, use a SAIL cylinder.
