Airtac SAIF Series Standard Cylinder with Valve SAIF63X175S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X175S-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 175mm 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 SAIF63X175S-08B
The AirTAC SAIF63X175S-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40. Driven by a DC24V terminal coil consuming 3.0 W, it integrates pneumatic and control functions into one assembly. While the cylinder body rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, making this the practical working range for the unit. The 63mm bore generates 1559N of push force at 0.5 MPa.
Equipped with a magnet for position sensing, this unit works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. The manifold connects to the cylinder via O10 x O6.5 PU tubing, and the valve port (1/4 inch) is distinct from the 3/8 inch cylinder port. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend upon energisation. This decentralized design eliminates remote plumbing, saving panel space.

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 SAIF63X175S-08B Is Used
Decentralized Automation
Eliminates the need for long air lines from a central control cabinet by switching directly at the machine station.
Mid-Force Positioning
Provides 1559N of push force at 0.5 MPa for clamping or lifting medium-weight workpieces in tight assembly cells.
Sensor-Ready Sorting
The integrated -S magnet allows CMSE and DMSE switches to confirm stroke endpoints for reliable conveyor diversion.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X175S-08B the Right Choice?
Choose this self-valved SAIF63 unit when decentralized machine stations require high force without the tubing runs of a remote valve bank. If your application needs less force, stepping down to a 50mm bore yields 982N push at 0.5 MPa. For heavier loads, an 80mm bore provides 2513N. Since the 5/2 valve routes air and holds position via pilot pressure, it is not a mechanical lock; for true load-holding under pressure loss, select a SAIL lock cylinder instead.
This specific configuration uses a 175mm stroke, which is below the 1500mm standard maximum, so no non-standard surcharge applies. The DC24V terminal connection offers low-power switching (3.0 W) with an IP65 rating and a 0.05s response time. When replacing, match the 63mm bore, 175mm stroke, 1/4 inch valve port, DC24V voltage, terminal entry, PT threads, and the -S magnet requirement.
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 SAIF63X175S-08B FAQ
The 63mm bore provides 1559N of push force and 1402N of pull force at 0.5 MPa. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
No, the 5/2 solenoid valve routes air and holds its last position via internal pilot pressure, but it is not a mechanical lock. If true load-holding is required under pressure loss, a SAIL lock cylinder should be used instead.
