Airtac SAIF Series Standard Cylinder with Valve SAIF63X300S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X300S-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 SAIF63X300S-08B
The AirTAC SAIF63X300S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve delivers a 25.0 mm2 effective area (Cv 1.40) and routes air directly through a manifold block using PU tubing (O10 x O6.5), eliminating the need for remote pneumatic plumbing. Equipped with a DC24V terminal coil drawing 3.0 W, it activates in 0.05 s with an IP65 rating. While the cylinder body rates to 1.0 MPa, the integrated valve limits the practical working pressure to 0.15-0.8 MPa.
This 63 mm bore unit generates 1559 N of push force at 0.5 MPa, reaching 2805 N at 0.9 MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence demands it. The included -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection across the 300 mm stroke.

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 SAIF63X300S-08B Is Used
Decentralized Automation Stations
Ideal for large machines with distributed stations, using the built-in 4M310-08 valve to actuate the 63 mm bore locally without running long pneumatic lines back to a central manifold.
Space-Constrained Machinery
Perfect for compact assemblies where mounting a separate 5/2 valve is impractical, leveraging the integrated manifold and DC24V terminal coil to minimize the overall footprint.
Retrofit and Upgrades
Simplifies upgrades on existing lines by providing a self-switching ISO 15552 profile cylinder that requires only an electrical signal to drive the 300 mm stroke.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X300S-08B the Right Choice?
Choose this self-contained SAIF63X300S-08B when decentralizing control across large machinery, as it replaces a separate cylinder and remote valve assembly to save panel space and wiring. If your application requires less force, stepping down to a 50 mm bore yields 982 N of push at 0.5 MPa; for heavier loads, an 80 mm bore provides 2513 N. Because the stroke is 300 mm, ensure adequate side-load support and use a guide rail to prevent rod binding.
This assembly uses a 4M310-08 valve with a 1/4" valve port and a 3/8" cylinder port. Remember that the 5/2 valve routes air but does not lock the load mechanically—unlike a SAIL lock or BSAI clamp-lock cylinder. For replacements, verify the 63 mm bore, 300 mm stroke, PT port threads, DC24V terminal coil, and the -S magnet option.
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 SAIF63X300S-08B FAQ
The 63 mm bore generates 1559 N of push force at 0.5 MPa and 2805 N at 0.9 MPa. The built-in 4M310-08 5/2 valve has a 25.0 mm2 orifice with a Cv of 1.40, supporting a max frequency of 4 cycles per second.
No, the built-in 5/2 solenoid valve routes air to drive the cylinder but does not function as a mechanical lock. The factory setting retracts the rod when the DC24V coil is energised, but it cannot hold a load without live pressure. For load-holding, consider a SAIL lock cylinder.
