Airtac SAIF Series Standard Cylinder with Valve SAIF63X800-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X800-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 800mm 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 SAIF63X800-08A
The AirTAC SAIF63X800-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, providing a Cv of 1.40 and a 25.0 mm2 effective area. Driven by an AC220V terminal coil consuming 3.5 VA, it activates in 0.05 s with an IP65 rating. While the cylinder body rates to 1.0 MPa, the integrated valve limits the practical operating pressure to 0.15-0.8 MPa. At 0.5 MPa, this 63 mm bore generates 1559 N of push force and 1402 N of pull force, operating at speeds of 30-800 mm/s.
This self-contained unit switches itself from a single coil signal, eliminating remote valves and reducing tubing for decentralized machine stations. The manifold connects to the cylinder via O10 x O6.5 PU tubing, and the valve port is 1/4 inch while the cylinder port is 3/8 inch. By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. Note that this 5/2 valve routes air and does not lock the load; for position holding, consider the SAIL series.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF63X800-08A Is Used
Decentralized Assembly Lines
Distributes actuation across large factory layouts without running long valve banks, using the built-in 4M310-08 valve to switch locally.
Long-Stroke Material Handling
Provides robust 1559 N push force over an 800 mm travel, requiring external guides to manage side loads during part transfer.
Space-Constrained Machinery
Saves valuable footprint by integrating the 5/2 valve directly on the profile cylinder, eliminating bulky external manifold blocks.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X800-08A the Right Choice?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is insufficient or a 80 mm bore (2513 N push at 0.5 MPa) is oversized. A self-valved SAIF63X800-08A beats a separate cylinder plus remote valve by saving panel space, wiring, and plumbing time across decentralized stations. Ensure your control system matches the AC220V terminal electrical entry and PT tapered threads. Since this unit lacks a magnet (-S not specified), it cannot host CMSE reed or DMSE electronic sensors without modification.
With an 800 mm stroke, this cylinder requires careful guidance to prevent excessive side loads from damaging the rod seals. When ordering a replacement, verify the 63 mm bore, 800 mm stroke, 1/4 inch valve port, AC220V voltage, terminal entry, PT threads, and no magnet.
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 SAIF63X800-08A FAQ
The 63 mm bore delivers 1559 N push and 1402 N pull force at 0.5 MPa. The built-in 4M310-08 valve provides a 25.0 mm2 orifice with a Cv of 1.40 and a max frequency of 4 cycles/sec.
The AC220V terminal coil drives the 5/2 valve, which by factory default retracts the rod when energised but can be reconfigured to extend. The valve routes air but does not lock the load; use SAIL or BSAI for position holding.
