Airtac SAIF Series Standard Cylinder with Valve SAIF63X500-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X500-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 500mm 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 SAIF63X500-08A
The AirTAC SAIF63X500-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve provides an effective flow area of 25.0 mm2 (Cv 1.40) and operates at a maximum frequency of 4 cycles per second. Configured with an AC220V coil drawing 3.5 VA, it uses a standard terminal electrical entry with IP65 protection and a quick 0.05s activation time. The cylinder itself features a 3/8 inch port, while the valve manifold connects via 1/4 inch ports and O10 x O6.5 PU tubing.
Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates from 0.15 to 0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa. At 0.5 MPa it generates 1559 N of push force and 1402 N of pull force. By default, the factory setting retracts the piston rod when the coil is energised, though you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design eliminates the need for a separate remote valve, drastically reducing plumbing and panel space across 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)

| 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 SAIF63X500-08A Is Used
Decentralized Automation Cells
Eliminates the need to run long valve tubing back to a central manifold, allowing independent cylinder control directly at remote machine stations.
Space-Constrained Assembly
The integrated 4M310 valve manifold shrinks the overall footprint compared to a standard cylinder and separate remote valve setup.
Material Handling Diverter
Provides robust 1559 N push force at 0.5 MPa to actuate routing gates and diverters on packaging lines without external panel valves.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X500-08A the Right Choice?
Select this 63mm bore model when a 50mm bore (offering 982 N push at 0.5 MPa) is insufficient for your load, but you want to avoid the larger envelope of an 80mm cylinder (2513 N push at 0.5 MPa). The integrated 4M310 valve makes the SAIF series superior to a standard SAI cylinder with remote plumbing when floor space is tight and running valve tubing is costly. Ensure you specify the exact 500mm stroke, 3/8 inch cylinder port, 1/4 inch valve port, AC220V terminal coil, PT threads, and no magnet when ordering replacements. Note that for a 500mm stroke, you should account for potential side loads and utilize appropriate guide rails to prevent rod binding.
Remember that the built-in 5/2 valve routes air but does not lock the load; if power or air drops, the cylinder will move. The variable air cushions (30mm stroke length) only decelerate the piston near the end of travel. For applications requiring true position holding under load loss, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock series instead. If you need position sensing, the standard extruded barrel lacks the -S magnet for CMSE reed or DMSE electronic 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 SAIF63X500-08A FAQ
At 0.5 MPa operating pressure, this 63mm bore cylinder generates 1559 N of push force and 1402 N of pull force. The built-in 4M310-08 5/2 valve provides an effective flow area of 25.0 mm2 (Cv 1.40) with a maximum operating frequency of 4 cycles per second.
No separate remote valve is needed; the integrated 4M310 valve switches the cylinder directly from the AC220V terminal coil signal. The factory default setting retracts the rod when energised, but you can reposition the valve to extend-when-energised.
