Airtac SAIF Series Standard Cylinder with Valve SAIF63X450-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X450-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 450mm 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 SAIF63X450-08A
The AirTAC SAIF63X450-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU pairs a 63mm bore with a 450mm stroke, utilizing a 1/4" valve port and an AC220V terminal electrical entry. The built-in valve provides an effective area of 25.0 mm2 (Cv 1.40) and switches at a maximum frequency of 4 cycles per second. Because the valve manifold routes air internally via PU tubing (O10 x O6.5), it eliminates the need for a separate remote valve, saving panel space and simplifying decentralized machine installations.
While the bare cylinder body rates to 1.0 MPa, the practical operating pressure for this assembled valved unit is 0.15-0.8 MPa, matching the valve limits. In its factory setting, the piston rod retracts when the coil is energized, but you can reconfigure it to extend-when-energized simply by repositioning the valve. At 0.5 MPa it generates 1559N of push force and 1402N of pull force. The coil consumes 3.5 VA, features IP65 protection, and activates in 0.05 seconds or less.

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)

| 0.5 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 SAIF63X450-08A Is Used
Decentralized Automation Stations
Ideal for large machines with multiple actuation points, as the built-in 4M310 valve eliminates long tubing runs back to a central manifold.
Long-Stroke Material Handling
Provides 1559N push force at 0.5 MPa over a 450mm stroke for pushing or lifting mid-weight products on a conveyor line.
Space-Constrained Retrofits
Drops into existing ISO 15552 footprints where adding external pneumatic valves and wiring is physically impossible or too costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X450-08A the Right Choice?
Choose this 63mm bore when a 50mm bore falls short on thrust (982N push at 0.5 MPa) but an 80mm unit provides excessive force (2513N push). The 450mm stroke is well within the 1500mm standard maximum for this bore, but at this length you should ensure adequate side-load guidance to prevent premature seal wear. This self-valved configuration excels over a standard SAI cylinder plus remote valve when you need to minimize plumbing across decentralized stations. To replace this unit, match the 63mm bore, 450mm stroke, PT1/4 valve port, AC220V terminal coil, and PT thread type. Note that the 5/2 valve routes air and is not a locking mechanism; for load-holding requirements, consider the SAIL series.
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 SAIF63X450-08A FAQ
At 0.5 MPa operating pressure, this 63mm bore cylinder delivers 1559N of push force and 1402N of pull force. The integrated 4M310-08 5/2 valve has a flow capacity of 25.0 mm2 (Cv 1.40).
The 4M310 valve is internal piloted and holds its last position pneumatically, not by a spring. By factory default, the coil energizes to retract the rod, but you can reposition the valve to extend-when-energized. It operates on AC220V with a terminal entry.
