Airtac SAIF Series Standard Cylinder with Valve SAIF63X225-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X225-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 225mm 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 SAIF63X225-08A
The AirTAC SAIF63X225-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. This integrated manifold block design eliminates the need for a remote valve, reducing plumbing and panel space for decentralized machine stations. Driven by an AC220V terminal entry coil drawing 3.5 VA, it responds in 0.05 s. The 4M310-08 valve provides a 25.0 mm2 flow (Cv 1.40) and operates at 4 cycles per second.
While the bare cylinder rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. The 63 mm bore generates 1559 N of push force at 0.5 MPa. The manifold connects to the cylinder via O10 x O6.5 PU tubing, distinguishing the 1/4" valve port from the cylinder's 3/8" port. Factory-set to retract the rod when energised, the valve can be repositioned to extend on signal.

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 SAIF63X225-08A Is Used
Decentralized Automation Cells
Ideal for large machines with multiple stations, eliminating long tubing runs by switching the cylinder directly at the point of use with a single AC220V signal.
Mid-Force Assembly Stations
Provides 1559 N of push force at 0.5 MPa for clamping or pressing components, where a 50 mm bore would lack the necessary thrust.
Retrofit and Upgrades
Perfect for upgrading existing ISO 15552 setups where adding a separate remote valve bank is cost-prohibitive or lacks panel space.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X225-08A the Right Choice?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is insufficient, but an 80 mm bore (2513 N) is excessive. The 225 mm stroke is well within the 1500 mm standard limit, though for any stroke at or above 300 mm, adding external guide rails is recommended to prevent rod side-loading and premature seal wear. The integrated 4M310-08 valve removes the need to run long air lines back to a centralized manifold, making it ideal for space-tight machines.
This assembly uses an AC220V terminal coil with PT tapered threads and no sensor magnet. The 5/2 valve routes air but does not lock the load; if static holding is required, consider an AirTAC SAIL lock cylinder. To replace this unit, match the 63 mm bore, 225 mm stroke, 1/4" valve port, AC220V terminal coil, and PT thread type.
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 SAIF63X225-08A FAQ
At 0.5 MPa, the 63 mm bore generates 1559 N of push force and 1402 N of pull force. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40).
The factory default setting retracts the piston rod when the AC220V coil is energised. By repositioning the 5/2 valve on the manifold block, it can be reconfigured to extend when energised.
