Airtac SAIF Series Standard Cylinder with Valve SAIF63X175-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X175-08B 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 SAIF63X175-08B
The AirTAC SAIF63X175-08B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. This integrated manifold block design eliminates the need for a remote valve, significantly reducing plumbing and panel space for decentralized machine stations. Driven by a DC24V terminal entry coil drawing 3.0 W, it responds in 0.05 s or less. The 4M310 valve provides a 25.0 mm2 effective area (Cv 1.40) and operates at a maximum frequency of 4 cycles per second.
While the base cylinder body rates to 1.0 MPa, the practical operating pressure for this assembled SAIF unit is 0.15-0.8 MPa due to the internal pilot valve limits. At 0.5 MPa, this 63 mm bore generates 1559 N of push thrust and 1402 N of pull thrust. The factory default setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and note the valve port (1/4) differs from the cylinder port (3/8).

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 SAIF63X175-08B Is Used
Decentralized Stations
Perfect for large machines with multiple stations, allowing local control from a single DC24V signal without running air lines back to a main panel.
Mid-Force Actuation
Delivers 1559 N of push force at 0.5 MPa, suitable for clamping, lifting, and pressing tasks in automated assembly lines.
Space-Tight Retrofits
The integrated 4M310-08 valve manifold saves valuable space, making it ideal for upgrading older machines where external valve banks will not fit.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X175-08B the Right Choice?
Choose this self-valved SAIF63X175-08B when you need to simplify wiring and eliminate long air tubing runs to a central manifold. It is ideal if you are stepping up from a 50 mm bore (which yields 982 N push at 0.5 MPa) to handle heavier loads, but do not require the full 2513 N push force of an 80 mm unit. The 175 mm stroke falls well within the 1500 mm standard maximum, meaning no non-standard configuration is required. Because this unit lacks a magnet (-S), it cannot host CMSE or DMSE sensors for position detection.
Remember that the built-in 5/2 valve routes air but does not lock the load; if you need true load-holding against pressure drops, consider the SAIL lock variant instead. When replacing this unit, verify the 63 mm bore, 175 mm stroke, 1/4 valve port, DC24V terminal coil, PT threaded ports, and standard carbon steel rod.
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 SAIF63X175-08B 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 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
No, the integrated 4M310 valve switches the cylinder directly from one DC24V coil signal. By factory default, the rod retracts when energised, but you can reposition the valve to extend-when-energised. It routes air but does not hold the load without live pressure.
