Airtac SAIF Series Standard Cylinder with Valve SAIF63X400S-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X400S-10A is a genuine double-acting ISO 15552 cylinder with a Ø63mm 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 SAIF63X400S-10A
The AirTAC SAIF63X400S-10A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This specific SKU specifies a 3/8" valve port, an AC220V terminal-entry coil, and a PT tapered thread. The built-in valve boasts a 30.0 mm2 orifice (Cv 1.68) and cycles up to 4 times per second. Because the valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa. At 0.5 MPa it generates 1559N of push force and 1402N of pull force.
By switching itself from a single coil signal, this unit eliminates remote plumbing and saves panel space, making it perfect for decentralized machine stations. 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 (O10 x O6.5), and the valve port differs from the cylinder port. The -S magnet option supports CMSE reed and DMSE electronic sensors for position feedback.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 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 SAIF63X400S-10A Is Used
Decentralized Assembly Lines
Eliminates the need for long air tubes back to a main valve bank, allowing independent control at each station.
Space-Constrained Machinery
The integrated manifold block saves valuable panel and footprint space in compact automated equipment.
Retrofit and Upgrades
Simplifies machine modifications by adding a self-switching actuator without re-plumbing an entire pneumatic rack.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X400S-10A the Right Choice?
Choose this 63mm bore if you need higher force than the 50mm version (982N push at 0.5 MPa) but want to avoid the larger envelope of the 80mm bore (2513N push). A self-valved SAIF beats a separate cylinder and remote valve when wiring and air tubing to a central panel is costly or impractical. The integrated 4M310 valve holds its position via internal pilot pressure, not a spring, but note it does not lock the load without live pressure; for true holding, consider a SAIL lock cylinder.
When replacing, match the 63mm bore, 400mm stroke, 3/8" valve port, AC220V voltage, terminal entry, PT thread, and -S magnet. Because the 400mm stroke exceeds 300mm, ensure adequate guide support to prevent excessive side loading on the rod. The carbon steel rod handles standard dynamic loads within the 30-800 mm/s speed range.
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 SAIF63X400S-10A FAQ
At 0.5 MPa, the 63mm bore provides 1559N push and 1402N pull force. The built-in 4M310-10 valve has a 30.0 mm2 effective area (Cv 1.68) for high flow capacity.
The built-in 5/2 valve allows the cylinder to control itself from one AC220V coil signal, removing the need for a separate remote valve. The factory setting retracts the rod when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
