Airtac SAIF Series Standard Cylinder with Valve SAIF63X300-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X300-08B 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 SAIF63X300-08B
The AirTAC SAIF63X300-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective area. It integrates a DC24V terminal coil drawing 3.0 W, protected to IP65 with a 0.05 s activation time. The assembly operates at 0.15-0.8 MPa because the internal pilot valve governs the working range, even though the bare cylinder rates to 1.0 MPa. At 0.5 MPa it generates 1559 N of push force and 1402 N of pull force.
The manifold connects the valve to the cylinder using O10 x O6.5 PU tubing, keeping the setup compact. The factory default retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. This self-contained design eliminates remote valve plumbing, saving panel space and simplifying decentralized installation across large machines.

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 SAIF63X300-08B Is Used
Decentralized Assembly Stations
Distributes actuation across large automated lines without running long valve tubing back to a central panel.
Space-Constrained Machinery
Saves valuable footprint by mounting the 4M310 valve directly on the profile cylinder via a manifold block.
Retrofit Automation
Simplifies machine upgrades by replacing standard cylinders with self-switching units that require only a DC24V signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X300-08B the Right Choice?
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) lacks thrust or a 80 mm bore (2513 N push) is oversized. The 300 mm stroke is well within the 1500 mm standard maximum, but at this length you must account for side loads and use a guide to prevent rod binding. The 4M310-08 valve provides ample flow for the 30-800 mm/s speed range. The DC24V terminal connection suits low-voltage control systems.
A self-valved SAIF excels over a separate cylinder and remote valve by cutting tubing runs and wiring. To replace this unit, match the 63 mm bore, 300 mm stroke, 1/4" valve port, DC24V terminal coil, PT thread, and standard carbon steel rod. Note that the 5/2 valve routes air but does not lock the load; for position holding, consider an AirTAC SAIL lock cylinder.
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 SAIF63X300-08B 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 provides a 25.0 mm2 effective area (Cv 1.40) and operates at up to 4 cycles per second.
No, it switches itself from one DC24V coil signal. By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised.
