Airtac SAIF Series Standard Cylinder with Valve SAIF63X400S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X400S-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 400mm 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 SAIF63X400S-08B
The AirTAC SAIF63X400S-08B is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve provides a Cv of 1.40 and operates at a maximum frequency of 4 cycles per second. Bundled with a DC24V terminal connection coil drawing 3.0 W, it includes a -S magnet for precise position sensing using CMSE reed or DMSE electronic solid-state switches. The manifold connects to the cylinder via O10 x O6.5 PU tubing, meaning the valve port (1/4) differs from the cylinder port (3/8).
While the bare cylinder rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. Generating 1559 N of push force at 0.5 MPa, it is configured by default to retract the rod when the coil is energised, which can be reconfigured to extend-when-energised by repositioning the valve. This self-switching design eliminates remote plumbing, saving panel space 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 (Ø63mm)

| 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-08B Is Used
Decentralized Automation Cells
Ideal for large machines with decentralized stations, eliminating long air tubing runs by driving the 63mm bore directly from a local DC24V signal.
Extended Stroke Assembly
The 400mm stroke suits parts handling and pressing tasks requiring 1559 N push force at 0.5 MPa, guided by external rails to manage side loads.
Compact Panel Retrofitting
Perfect for retrofits where panel space is tight, using the built-in 4M310 valve and O10 x O6.5 PU tubing to minimize pneumatic plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X400S-08B the Right Choice?
Choose this 63mm bore when a 50mm bore (offering 982 N push at 0.5 MPa) lacks sufficient thrust, but a 80mm bore (2513 N push at 0.5 MPa) is physically too large. The SAIF63X400S-08B is ideal for decentralized installations where routing air tubing to a remote valve is costly, as it switches itself from one DC24V coil signal. The 400mm stroke requires attention to side loads; ensure external guide rails are used to prevent rod binding.
When specifying replacements, verify the 63mm bore, 400mm stroke, 4M310-08 valve with 1/4 port, DC24V voltage, PT tapered thread, terminal entry, and -S magnet. Remember the 5/2 valve routes air and is not a mechanical lock; if unpowered load holding is required, consider 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 SAIF63X400S-08B FAQ
The 63mm bore generates 1559 N push and 1402 N pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40).
No, the 5/2 valve routes air but is not a lock; it cannot hold loads without live pressure. No separate remote valve is needed because the 4M310 valve is built-in, defaulting to retract-when-energised but reconfigurable to extend.
