Airtac SAIF Series Standard Cylinder with Valve SAIF63X175-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X175-08A 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 SAIF63X175-08A
The AirTAC SAIF63X175-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. This specific SKU specifies an AC220V terminal coil connection and PT tapered threads. Driven by a single electrical signal, it eliminates the need for a remote valve bank, saving panel space and simplifying plumbing for decentralized machine stations. The integrated valve delivers a 25.0 mm2 effective orifice (Cv 1.40) and supports a maximum frequency of 4 cycles per second.
While the bare cylinder body is rated for 1.0 MPa, the practical operating pressure for this valved assembly is 0.15-0.8 MPa. At 0.5 MPa it generates 1559 N of push thrust and 1402 N of pull thrust. The manifold connects to the cylinder via O10 x O6.5 PU tubing, and the 3/8 inch cylinder port differs from the 1/4 inch valve port. Factory-set to retract when energized, the valve can be repositioned to extend on signal if your sequence requires it.

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 SAIF63X175-08A Is Used
Decentralized Stations
Eliminates long air lines by mounting the 4M310 valve directly on the cylinder, perfect for large assembly lines with multiple independent actuators.
Compact Machinery
Saves valuable panel space by integrating the AC220V coil and valve manifold directly onto the ISO 15552 profile cylinder body.
Retrofit Installations
Ideal for upgrading existing pneumatic setups where running new tubing from a central valve island is too expensive or complex.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X175-08A the Right Choice?
Choose this 63 mm bore when a 50 mm bore (offering 982 N push at 0.5 MPa) is insufficient, but an 80 mm bore (2513 N push) would be excessive. The integrated 4M310 valve makes the SAIF63X175-08A ideal for space-tight machines where routing tubing to a distant manifold is costly or impractical. Because the 5/2 valve only routes air, it cannot hold a load without live pressure; for positive locking, consider the SAIL series instead. The 175 mm stroke is well within standard limits, though proper guide support is always recommended for smooth operation.
When ordering a replacement, verify the 63 mm bore, 175 mm stroke, 1/4 inch valve port, AC220V voltage, terminal electrical entry, and PT thread type. This unit uses a standard carbon steel rod and does not include a magnet for sensors; add the -S suffix if CMSE or DMSE position detection is required.
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 SAIF63X175-08A FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) with a maximum operating frequency of 4 cycles per second.
No, the SAIF63X175-08A features a built-in 5/2 solenoid valve that drives the cylinder from a single AC220V terminal connection. By default, the rod retracts when the coil is energized, but the valve can be repositioned to extend-when-energized.
