Airtac SAIF Series Standard Cylinder with Valve SAIF63X300-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X300-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 300mm 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 SAIF63X300-08A
The AirTAC SAIF63X300-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve provides a Cv of 1.40 and eliminates the need for remote plumbing, routing air directly via a PU tube (O10 x O6.5) to the 3/8 inch cylinder ports. Equipped with an AC220V terminal entry coil drawing 3.5 VA, it activates in under 0.05 seconds. Although the cylinder body rates to 1.0 MPa, the integrated valve limits the practical working pressure to 0.15-0.8 MPa.
Delivering 1559 N of push force at 0.5 MPa, this self-switching unit is designed for decentralized machine stations. From the factory, the piston rod retracts when the coil is energized, but you can reposition the valve to extend on signal. The 5/2 valve holds its position via internal pilot pressure, not a spring. Note that neither the valve nor the end cushions act as a load lock; for holding tasks, consider the SAIL series.

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 SAIF63X300-08A Is Used
Decentralized Automation Cells
Ideal for large machines with distributed stations, using the built-in 4M310 valve to cut down on centralized valve banks and complex tubing runs.
Material Diverting
Provides 1559 N of push force at 0.5 MPa to actuate diverter arms on conveyors, responding in under 0.05 seconds for reliable sorting.
Space-Constrained Retrofits
Fits easily into tight machine envelopes where adding a separate remote valve and manifold would be physically impossible.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X300-08A 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 SAIF63X300-08A is ideal for decentralized installations where running separate valve tubing wastes panel space and complicates wiring. The AC220V terminal coil offers straightforward DIN wiring. Because the 300 mm stroke exceeds standard minimums, ensure your mounting resists side loads by using FA or LB foot mounts and external guides if heavy loads are attached.
When ordering a replacement, verify the 63 mm bore, 300 mm stroke, PT 3/8 inch cylinder port, 4M310-08 valve with 1/4 inch port, AC220V voltage, terminal entry, and standard carbon steel rod. Because -S is not specified, this unit lacks a piston magnet for CMSE or DMSE sensors.
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 SAIF63X300-08A FAQ
At 0.5 MPa it provides 1559 N push and 1402 N pull force. While the cylinder body rates to 1.0 MPa, the built-in 4M310-08 valve operates at 0.15-0.8 MPa, making the practical working range 0.15-0.8 MPa.
The factory setting retracts the rod when the coil is energized. By repositioning the 5/2 valve on the manifold block, you can reconfigure it to extend when energized. The valve holds its position via internal pilot pressure, not a spring.
