Airtac SAIF Series Standard Cylinder with Valve SAIF63X80-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X80-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 80mm 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 SAIF63X80-08B
The AirTAC SAIF63X80-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry consuming 3.0 W, an IP65 rating, and a PT1/4 valve port. The valve provides a 25.0 mm2 effective area (Cv 1.40) and switches up to 4 cycles per second. Because the manifold links the valve to the 3/8 cylinder port via O10 x O6.5 PU tubing, it operates autonomously from a single coil signal.
While the cylinder body rates to 1.0 MPa, the practical operating range for this assembled unit is 0.15-0.8 MPa due to the internal pilot valve limits. Delivering 1559 N push and 1402 N pull force at 0.5 MPa, it is ready 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 if your sequence requires it.

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 SAIF63X80-08B Is Used
Decentralized Stations
Eliminates long tubing runs from a central panel by switching locally via the DC24V terminal coil, ideal for distributed automation cells.
Mid-Force Clamping
Provides 1559 N of push force at 0.5 MPa for holding parts securely during machining without requiring external valves.
Retrofit Upgrades
Drops into existing ISO 15552 mounts to replace a separate cylinder and valve setup, clearing valuable space on tight machinery.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X80-08B the Right Choice?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) lacks thrust but an 80 mm bore (2513 N) is physically too large. The self-valved SAIF architecture eliminates the need for a remote valve bank, saving panel space and cutting plumbing labor across large machines. This model uses a DC24V terminal coil with PT tapered threading; specify the -S suffix if you need CMSE or DMSE sensors for position feedback.
For stroke lengths of 80 mm, side-load is minimal, but always verify guide alignment. Remember that the 5/2 valve routes air and is not a locking mechanism—the air cushion only decelerates near stroke end. If your application requires true load holding without live pressure, consider the SAIL lock variant 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 SAIF63X80-08B FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. The built-in 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40).
No, the built-in 4M310 valve switches the cylinder directly from the DC24V coil signal. By default, the rod retracts when energised, but the valve can be repositioned to extend-when-energised.
