Airtac SAIF Series Standard Cylinder with Valve SAIF63X800S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X800S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 800mm 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 SAIF63X800S-08A
The AirTAC SAIF63X800S-08S is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve, offering a Cv of 1.40 and a 25.0 mm2 effective area. Driven by an AC220V terminal entry coil consuming 3.5 VA, it integrates the manifold block using O10 x O6.5 PU tubing. The cylinder features a carbon steel rod and a -S magnet for precise position sensing with CMSE reed and DMSE electronic switches.
Because the 4M310 valve operates at 0.15-0.8 MPa, the practical working range for this assembled SAIF 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 and 1402 N of pull force. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This decentralized design requires just one coil signal to switch itself, eliminating remote valves and reducing panel space.

| 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 SAIF63X800S-08A Is Used
Decentralized Automation Stations
Ideal for large factory layouts where running valve tubing back to a central panel is costly, this self-switching cylinder operates independently from a single AC220V signal.
Extended Stroke Handling
The 800 mm stroke suits material transfer and part ejection tasks, while the -S magnet enables precise end-of-stroke confirmation via DMSE sensors.
Space-Constrained Machinery
By mounting the 4M310 valve directly on the profile body via a manifold block, it saves valuable panel space and simplifies machine wiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X800S-08A the Right Choice?
Choose this self-valved SAIF63X800S-08A when you need to eliminate separate remote valves and minimize tubing across decentralized machine stations. If your application requires less push force, stepping down to a 50 mm bore yields 982 N at 0.5 MPa; if you need more thrust, an 80 mm bore provides 2513 N at the same pressure. The integrated 4M310 valve achieves a maximum frequency of 4 cycles per second. For replacement, match the 63 mm bore, 800 mm stroke, 1/4" valve port, AC220V terminal coil, PT thread, and -S magnet.
With an 800 mm stroke, this cylinder is susceptible to side loads; ensure you use an external guide or load support to prevent rod binding and premature seal wear. Note that the built-in 5/2 valve routes air but does not lock the load mechanically—air cushions only decelerate near stroke ends. For true load-holding requirements, consider the AirTAC SAIL pneumatic lock series 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 SAIF63X800S-08A FAQ
The 63 mm bore cylinder provides 1559 N of push force and 1402 N of 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) and supports a maximum frequency of 4 cycles per second.
No, the 5/2 valve routes air to drive the double-acting cylinder but does not mechanically lock the load. By default, the rod retracts when the AC220V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve. For load-holding, use a SAIL lock cylinder.
