Airtac SAIF Series Standard Cylinder with Valve SAIF63X100-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X100-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 100mm 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 SAIF63X100-08B
The AirTAC SAIF63X100-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific build uses a DC24V terminal coil drawing 3.0 W, firing in 0.05 s with an IP65 rating. The built-in valve provides a Cv of 1.40 and routes air through O10 x O6.5 PU tubing, which differs from the cylinder's 3/8 port. Because the valve operates at 0.15-0.8 MPa, the practical working range for the assembled unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa. At 0.5 MPa it delivers 1559 N of push force.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This self-switching design means one coil signal drives the cylinder directly, eliminating remote valves and extra tubing for decentralized machine stations.

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 SAIF63X100-08B Is Used
Decentralized Stations
Eliminates the need to run long valve tubing back to a central panel, driving the 63 mm bore directly from a local DC24V signal.
Mid-Force Clamping
Provides 1559 N of push force at 0.5 MPa for securing mid-sized workpieces without requiring a separate remote valve assembly.
Space-Tight Machine Retrofits
Ideal for upgrading existing ISO 15552 lines where adding external valve manifolds is physically constrained.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X100-08B the Right Choice?
Choose this 63 mm bore when 50 mm (982 N push at 0.5 MPa) is too weak, but the 80 mm (2513 N push at 0.5 MPa) is physically oversized. The integrated 4M310 valve handles up to 4 cycles per second. Select this DC24V terminal entry version for standard low-voltage control panels where a quick disconnect is preferred. Remember that the 5/2 valve routes air but does not hold the load without live pressure; for position holding, consider the SAIL lock variant. When replacing, match the 63 mm bore, 100 mm stroke, 08 valve port, DC24V voltage, PT thread, and terminal entry. As this stroke is 100 mm, no external guide 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 SAIF63X100-08B FAQ
The 63 mm bore generates 1559 N push and 1402 N pull force at 0.5 MPa. The built-in 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40).
Yes. The factory setting retracts the rod when the coil is energised, but you can reposition the built-in valve to extend-when-energised. The valve holds its position by pilot pressure, not a spring.
