Airtac SAIF Series Standard Cylinder with Valve SAIF63X500S-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X500S-10B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 500mm stroke and a built-in 4M310-10 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 SAIF63X500S-10B
The AirTAC SAIF63X500S-10B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-10 5/2 solenoid valve, delivering a Cv of 1.68 and a 30 mm2 effective orifice. Driven by a DC24V terminal coil drawing 3.0 W with an IP65 rating and a maximum 0.05 s response time, it generates 1559 N of push thrust at 0.5 MPa. Although the bare cylinder is rated for 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, establishing the practical working range for this assembled unit at 0.15-0.8 MPa.
By integrating the valve directly onto the manifold block via O10 x O6.5 PU tubing, this unit eliminates the need for a separate remote valve, reducing panel space and plumbing for decentralized installations. The factory setting energizes the coil to retract the piston rod, but this can be reconfigured to extend-when-energised simply by repositioning the valve. This -S variant includes a magnet for position sensing and utilizes a carbon steel piston rod with PT tapered threads.

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)

| 0.7 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 SAIF63X500S-10B Is Used
Decentralized Automation Stations
Ideal for large machines with multiple stations, eliminating long tubing runs by switching locally via the built-in 4M310 valve and a single DC24V electrical signal.
Long-Stroke Material Handling
Provides 1559 N push force at 0.5 MPa over a 500 mm stroke for pushing or lifting tasks, requiring external guide rails to manage side loads.
Space-Constrained Retrofits
Drops into existing ISO 15552 footprints where panel space is scarce, combining the cylinder and valve into one compact assembly with PT tapered ports.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X500S-10B the Right Choice?
Choose this 63 mm bore when an application requires more force than a 50 mm cylinder (which provides 982 N push at 0.5 MPa) but does not need the full 2513 N push of an 80 mm unit. The self-valved SAIF architecture is ideal for space-tight machines or retrofits where running long air tubing back to a centralized valve bank is costly, as it switches itself from a single coil signal. For this 500 mm stroke, ensure adequate side-load guidance to prevent rod binding, as the air cushion only decelerates near the stroke end and does not lock the load.
When ordering a replacement, verify the 63 mm bore, 500 mm stroke, 4M310 valve with a port code 10 (3/8" valve port), DC24V voltage, terminal electrical entry, PT thread type, and the -S magnet for CMSE or DMSE sensors. Note that the 3/8" cylinder port differs from the valve port. For applications requiring true load holding without live pressure, consider the SAIL lock variant instead.
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 SAIF63X500S-10B FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. The integrated 4M310-10 5/2 valve provides a 30 mm2 effective orifice with a Cv of 1.68.
No separate pilot is needed; the 4M310 valve is internally piloted. The factory default retracts the rod when the DC24V coil is energized, but you can reposition the valve on the manifold to make it extend-when-energised.
