Airtac SAIF Series Standard Cylinder with Valve SAIF63X1000S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X1000S-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 SAIF63X1000S-08B
The AirTAC SAIF63X1000S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective orifice. Driven by a DC24V terminal coil drawing 3.0 W, it achieves IP65 protection and a 0.05 s activation time. Because the integrated valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled unit, 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.
This self-switching design eliminates the need for a separate remote valve, reducing tubing and panel space for decentralized machine stations. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and the valve port (1/4") differs from the cylinder port (3/8"). Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised. The -S magnet option supports position sensing with AirTAC CMSE reed or DMSE electronic switches.

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 SAIF63X1000S-08B Is Used
Decentralized Automation
Ideal for large machines with multiple stations, eliminating long tubing runs by controlling the cylinder directly from a single DC24V signal.
Material Handling
Provides 1559 N push force at 0.5 MPa for diverting or lifting heavy pallets, with a 1000 mm stroke for extended reach.
Space-Constrained Retrofit
The integrated valve manifold saves panel space, making it perfect for upgrading existing lines where external valve islands cannot fit.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X1000S-08B the Right Choice?
Choose this 63 mm bore when a 50 mm bore (providing 982 N push at 0.5 MPa) is insufficient, but an 80 mm bore (2513 N push) would be excessive. The SAIF63X1000S-08B is optimal for decentralized stations where running separate valve tubing is costly, as one DC24V terminal signal directly controls the cylinder. The PT-threaded valve port is 1/4", while the cylinder port is 3/8".
For replacement, verify the 1000 mm stroke, 4M310-08 valve, DC24V voltage, terminal entry, PT threads, and -S magnet. Because the stroke is 1000 mm, use a guide rail to prevent rod side-loading and premature seal wear. Note that the built-in 5/2 valve routes air but does not lock the load; for position holding under pressure loss, 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 SAIF63X1000S-08B FAQ
The 63 mm bore generates 1559 N push and 1402 N pull at 0.5 MPa. The built-in 4M310-08 valve has a 25.0 mm2 effective area (Cv 1.40) and a max frequency of 4 cycles/sec.
The DC24V coil draws 3.0 W and the 5/2 valve holds position via internal pilot, not a spring. By default, the rod retracts when energised but can be reconfigured to extend. The valve routes air but does not lock the load without live pressure.
