Airtac SAIF Series Standard Cylinder with Valve SAIF63X200S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X200S-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 SAIF63X200S-08B
The AirTAC SAIF63X200S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific build uses a DC24V terminal coil drawing 3.0 W with an IP65 rating, actuating in 0.05 s. The built-in valve boasts a 25.0 mm2 orifice (Cv 1.40), efficiently driving the 63 mm bore which generates 1559 N of push force at 0.5 MPa. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled unit, despite the cylinder body rating of 1.0 MPa. A factory setting retracts the rod when the coil energises, which technicians can reconfigure to extend-when-energised by repositioning the valve.
This self-contained unit eliminates the need for a separate remote valve, significantly reducing panel space and plumbing complexity for decentralized machine stations. The manifold connects to the cylinder using O10 x O6.5 PU tubing, while the valve features a 1/4" PT port, distinct from the cylinder's 3/8" port. Equipped with a magnet, it supports CMSE reed and DMSE electronic sensors for precise position feedback.

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 SAIF63X200S-08B Is Used
Decentralized Assembly Lines
Eliminates remote valve banks, allowing independent cylinder control across large automated manufacturing systems.
Compact Clamping Fixtures
Provides robust 1559 N clamping force in tight spaces without requiring external pneumatic plumbing.
Retrofitted Material Handling
Simplifies machine upgrades by integrating the 5/2 valve directly on the actuator, minimizing new tubing runs.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X200S-08B the Right Choice?
Select this 63 mm bore when 50 mm falls short (offering 982 N push at 0.5 MPa) but 80 mm is excessive (delivering 2513 N). The SAIF63X200S-08B is optimal for space-constrained machines where running individual valve tubing is costly. It provides a complete switching solution from one 24V DC signal. Remember that the 5/2 valve routes air and is not a lock; the cushion only decelerates near stroke end. For load-holding requirements, consider the SAIL series. When ordering replacements, verify the 200 mm stroke, 1/4" valve port, DC24V terminal coil, PT thread, and the -S magnet requirement.
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 SAIF63X200S-08B FAQ
The 63 mm bore generates 1559 N of push force at 0.5 MPa and 2182 N at 0.7 MPa. The built-in 4M310-08 5/2 valve has an effective flow area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
No, the 5/2 solenoid valve routes air but does not lock the load; it holds position via live pilot pressure. The factory setting retracts the rod when energised, but it can be reconfigured to extend-when-energised. For true mechanical load holding, use the SAIL series.
