Airtac SAIF Series Standard Cylinder with Valve SAIF63X200-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X200-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 200mm 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 SAIF63X200-08B
The AirTAC SAIF63X200-08B is a double-acting ISO 15552 profile cylinder paired with a built-in 4M310-08 5/2 solenoid valve. Driven by a DC24V terminal-entry coil drawing 3.0 W, it delivers a Cv of 1.40 and generates 1559N of push force at 0.5 MPa. The integrated manifold uses a PU tube (O10 x O6.5) to bridge the valve and cylinder, meaning you only need one electrical signal to actuate the unit. Because the 5/2 valve operates from 0.15-0.8 MPa, this defines the practical working pressure for the assembled SAIF, even though the bare cylinder rates to 1.0 MPa.
Factory configured to retract the piston rod when the coil is energised, the valve can be physically repositioned to extend-when-energised if your sequence demands it. This self-contained design eliminates remote valve plumbing, saving panel space and making it ideal for decentralized stations across large machinery. Note that while the valve routes air, it does not hold the load without live pressure; for true locking needs, consider the SAIL series.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF63X200-08B Is Used
Decentralized Assembly Lines
Eliminates the need for a central valve bank, letting each station control its own clamp via a single DC24V signal.
Space-Constrained Machinery
The integrated manifold block saves valuable panel and footprint space in tight automated cells.
Retrofit Automation
Ideal for upgrading older machines where routing new pneumatic tubing back to a remote valve is costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X200-08B the Right Choice?
Choose this 63mm bore when a 50mm cylinder is insufficient—yielding 982N push at 0.5 MPa—or step down to a 50mm bore if 1559N is overkill for your payload. The SAIF63X200-08B excels over a separate cylinder and remote valve setup when you need to minimize tubing runs and wiring complexity in decentralized machine layouts. It operates at 30-800 mm/s.
At 200mm stroke, the unit is well within standard limits, but always ensure adequate guide support to handle side loads. Replacement requires matching the 63mm bore, 200mm stroke, 4M310-08 valve (1/4" valve port), DC24V voltage, PT thread, and terminal entry. Without a magnet (-S), it cannot host CMSE or DMSE 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 SAIF63X200-08B FAQ
The 63mm bore generates 1559N push and 1402N pull force at 0.5 MPa. The built-in 4M310-08 valve provides an effective area of 25.0 mm2 (Cv 1.40).
No, it features a built-in 5/2 valve. By default, the rod retracts when the DC24V coil is energised, but the valve can be repositioned to extend-when-energised. It operates on 0.15-0.8 MPa.
