Airtac SAIF Series Standard Cylinder with Valve SAIF63X50-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X50-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 50mm 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 SAIF63X50-08A
The AirTAC SAIF63X50-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific configuration uses an AC220V coil with a terminal electrical entry consuming 3.5 VA, protected to IP65 with a 0.05s response time. The built-in valve offers a 25.0mm2 effective area (Cv 1.40) and routes air through a PU tube (O10 x O6.5) to the 3/8 cylinder port. Because the valve operates at 0.15-0.8 MPa, the practical working pressure for the assembled SAIF unit is 0.15-0.8 MPa, even though the cylinder body itself rates to 1.0 MPa. At 0.5 MPa it generates 1559N of push force.
By default, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design means one 220V signal drives the actuator directly, eliminating the need for a separate remote valve and significantly reducing plumbing and panel space across decentralized installations.

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 SAIF63X50-08A Is Used
Decentralized Stations
Perfect for large machines with multiple nodes, allowing local control from a single AC220V signal without running long valve tubing back to a central panel.
Space-Tight Machinery
The integrated 4M310 valve manifold eliminates the need for a separate valve block, saving critical envelope space in compact automation equipment.
Retrofit Automation
Ideal for upgrading existing lines where adding pneumatic plumbing is costly, providing a self-contained 1559N actuator driven directly by a 220V terminal connection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X50-08A the Right Choice?
Choose this 63mm bore if your application requires the 1559N push force at 0.5 MPa; stepping down to a 50mm bore drops the push force to 982N, while an 80mm bore increases it to 2513N. A self-valved SAIF63X50-08A is highly advantageous over a separate cylinder and remote valve when space is tight and running dedicated valve tubing across a large machine is costly. It provides clean, localized control from a single AC220V terminal connection. When specifying replacements, confirm the 50mm stroke, 3/8 cylinder port, PT thread type, 1/4 valve port (code 08), AC220V voltage, terminal entry, and standard carbon steel rod. Note that the 5/2 valve routes air but does not lock the load; for position holding under zero pressure, consider the SAIL lock series 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 SAIF63X50-08A FAQ
The cylinder generates 1559N of push force and 1402N of pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve provides an effective area of 25.0mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
It uses a 5/2 solenoid valve that holds position via internal pilot pressure, not a spring. The factory default retracts the rod when energised, but it can be reconfigured to extend-when-energised. This specific SKU uses an AC220V terminal coil, though AC110V, AC24V, DC24V, and DC12V options are available.
