Airtac SAIF Series Standard Cylinder with Valve SAIF63X50S-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X50S-10A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 50mm stroke and a built-in 4M310-10 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 SAIF63X50S-10A
The AirTAC SAIF63X50S-10A is a double-acting ISO 15552 profile cylinder with a built-in 4M310-10 5/2 solenoid valve, delivering a 30.0 mm2 effective area (Cv 1.68). Driven by an AC220V terminal entry coil drawing 3.5 VA, it integrates switching directly on the actuator. The cylinder body features a PT3/8 port, while the integrated valve utilizes a PT3/8 port via a manifold block connected by O10 x O6.5 PU tubing. Because the 5/2 valve operates at 0.15-0.8 MPa, this defines the practical working range for the assembled unit, despite the bare cylinder rating of 1.0 MPa.
This model produces 1559 N of push force and 1402 N of pull force at 0.5 MPa. It includes a magnet (-S) for position sensing with AirTAC CMSE reed and DMSE electronic switches. By default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve. It switches itself from one coil signal, eliminating remote plumbing and making it ideal for decentralized stations across large machines.

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 SAIF63X50S-10A Is Used
Decentralized Automation Stations
Eliminates the need for long valve tubing runs across large machines by integrating the 4M310 valve directly on the cylinder for localized control.
Mid-Force Positioning
Provides 1559 N of push force at 0.5 MPa for clamping or lifting tasks where a 50 mm bore would be insufficient.
Retrofit Space-Tight Machines
Ideal for upgrading older equipment where mounting a separate remote valve bank is physically impossible or too costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X50S-10A the Right Choice?
Choose this 63 mm bore when you need higher thrust than the 50 mm class (which provides 982 N push at 0.5 MPa), but want to avoid the larger envelope of an 80 mm unit (2513 N push at 0.5 MPa). The self-valved SAIF design beats a separate cylinder and remote valve setup by drastically reducing panel space and tubing runs. The AC220V terminal coil offers IP65 protection and a 0.05 s response time. For exact replacements, verify the 50 mm stroke, PT3/8 valve port, AC220V voltage, terminal entry, PT thread, and -S magnet.
Note that the built-in 5/2 valve routes air to move the cylinder but does not lock or hold the load without live pressure. For secure load-holding applications, consider an AirTAC SAIL lock cylinder or BSAI clamp-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 SAIF63X50S-10A 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 4M310-10 5/2 valve has an effective area of 30.0 mm2 (Cv 1.68) and a maximum frequency of 4 cycles per second.
It uses an internal piloted 5/2 solenoid valve that holds its last position by pilot pressure, not a spring. This specific model uses an AC220V terminal entry coil (3.5 VA, IP65). The factory setting retracts the rod when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
