Airtac SAIF Series Standard Cylinder with Valve SAIF63X80-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X80-08A 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 SAIF63X80-08A
The AirTAC SAIF63X80-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. The built-in valve provides an effective flow rate of 25.0 mm2 (Cv 1.40) and mounts directly via a manifold block using O10xO6.5 PU tubing. Driven by an AC220V terminal entry coil consuming 3.5 VA, it switches itself from a single electrical signal. While the bare cylinder rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa.
This 63mm bore generates 1559N of push force and 1402N of pull force at 0.5 MPa. By default, the factory setting retracts the piston rod when the coil is energised, though you can reconfigure it to extend-when-energised by repositioning the valve. It eliminates the need for a separate remote valve, reducing panel space and tubing complexity for decentralized machine stations.

| 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 SAIF63X80-08A Is Used
Decentralized Machine Stations
Ideal for large assembly lines where running individual valve tubing back to a central manifold is costly and complex.
Mid-Force Actuation
Provides 1559N push force at 0.5 MPa, suitable for medium-duty clamping, pressing, and lifting tasks.
Space-Constrained Retrofits
The built-in valve manifold saves valuable panel and footprint space in tight machinery upgrades.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X80-08A the Right Choice?
Choose this 63mm bore when a 50mm bore (offering 982N push at 0.5 MPa) is insufficient, but an 80mm bore (2513N push) is physically too large. The integrated 4M310 valve offers a high Cv of 1.40, matching the air demand of this bore. The AC220V terminal coil provides robust industrial voltage compatibility with a 0.05s response time and IP65 protection. Ensure your replacement matches the 80mm stroke, 3/8" cylinder port, 1/4" valve port, PT thread, and no-magnet configuration.
Select a self-valved SAIF unit over a separate cylinder and remote valve when decentralizing a large machine, as it drastically cuts plumbing and wiring costs. Note that the 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, consider the SAIL lock series. The cylinder achieves speeds of 30-800 mm/s, and the variable air cushions decelerate the rod near stroke ends without acting as a brake.
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 SAIF63X80-08A FAQ
At 0.5 MPa, this 63mm bore cylinder generates 1559N of push force and 1402N of pull force. The integrated 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40) to handle the required air volume.
It uses an AC220V terminal entry coil (3.5 VA, IP65) to drive the integrated 5/2 valve. By factory default, energising the coil retracts the rod, but this can be reconfigured to extend-when-energised by repositioning the valve. It switches itself directly, eliminating the need for a separate remote valve.
