Airtac SAIF Series Standard Cylinder with Valve SAIF63X1000-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X1000-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 1000mm 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 SAIF63X1000-08B
The AirTAC SAIF63X1000-08B is a double-acting ISO 15552 profile cylinder paired with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and an effective orifice of 25.0 mm2. Driven by a DC24V terminal coil drawing 3.0 W, it activates in 0.05 s or less with IP65 protection. The assembly operates at 0.15-0.8 MPa because the internal pilot valve governs the working pressure, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it provides 1559 N of push force and 1402 N of pull force.
This decentralized unit switches itself from a single coil signal, eliminating remote plumbing and saving panel space. The manifold links the valve to the cylinder via a PU tube (O10 x O6.5). Factory-set to retract the rod when energized, the valve can be repositioned to extend on signal. The carbon steel piston rod has an M16x1.5 thread, and the cylinder port is PT1/4.

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 SAIF63X1000-08B Is Used
Decentralized Automation
Perfect for large factory stations where running remote valve tubing is costly, as the built-in 4M310-08 valve handles switching directly on the cylinder.
Material Handling
Provides 1559 N of push force at 0.5 MPa for pushing or gating heavy loads on long conveyor lines without needing external pneumatic panels.
Compact Machining
Saves valuable machine envelope by combining the ISO 15552 actuator and 5/2 valve into one assembly, ideal for tight retrofit spaces.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X1000-08B 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 at 0.5 MPa) is oversized. The integrated 4M310-08 valve removes the need for a separate remote valve, making it ideal for large machines with decentralized stations. The DC24V terminal coil offers safe low-voltage control. For load-holding rather than routing air, use the SAIL lock series instead of relying on the 5/2 valve or air cushions. To replace this unit, match the 63 mm bore, 1000 mm stroke, PT1/4 cylinder port, 1/4 inch valve port, DC24V voltage, terminal entry, and PT thread. At 1000 mm stroke, use a guide to prevent rod side-loading and ensure smooth operation.
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 SAIF63X1000-08B 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 has an effective area of 25.0 mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
The 5/2 valve routes air but does not hold the load without live pressure; for true locking use the SAIL series. Factory-set to retract when the DC24V coil energizes, the valve can be repositioned to extend on signal, removing the need for a separate remote valve.
