Airtac SAIF Series Standard Cylinder with Valve SAIF63X150S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X150S-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 150mm 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 SAIF63X150S-08B
The AirTAC SAIF63X150S-08B is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40. It features a 63mm bore generating 1559N push force at 0.5MPa. Driven by a DC24V terminal entry coil consuming 3.0W, the unit includes a -S magnet for CMSE reed or DMSE electronic sensors. The carbon steel rod and PT tapered threads ensure robust pneumatic connections.
Because the cylinder rates to 1.0MPa but the integrated valve operates at 0.15-0.8MPa, the practical working range for this assembled unit is 0.15-0.8MPa. The manifold links the valve to the cylinder via PU tubing, meaning the 1/4" valve port differs from the 3/8" cylinder port. By default, the factory setting retracts the rod when the coil is energised, though you can reconfigure it to extend-when-energised by repositioning the valve.

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 SAIF63X150S-08B Is Used
Decentralized Machine Stations
Eliminates the need to run long valve tubing back to a central panel. Each station controls itself with a single DC24V signal.
Space-Constrained Automation
The integrated manifold block saves valuable envelope space compared to a separate cylinder and remote valve setup.
Retrofit & Upgrades
Ideal for upgrading existing ISO 15552 lines where adding external pneumatic plumbing is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X150S-08B the Right Choice?
Choose this self-valved SAIF unit when you need decentralized control across a large machine, eliminating remote valve plumbing and saving panel space. If your application requires less force, the 50mm bore neighbour offers 982N push at 0.5MPa; for higher force, the 80mm bore provides 2513N. Remember that the 5/2 valve routes air but does not hold the load without live pressure—use a SAIL lock cylinder for position holding needs.
To replace this model, match the 63mm bore, 150mm stroke, 4M310-08 valve with 1/4" valve port, DC24V voltage, terminal entry, PT thread, and the -S magnet. Operating speed is 30-800mm/s. Since the 150mm stroke is under 300mm, standard guide rules are relaxed, but always verify side-load limits for your specific mounting.
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 SAIF63X150S-08B FAQ
The 63mm bore generates 1559N push force at 0.5MPa and 2805N at 0.9MPa. The built-in 4M310-08 valve provides an effective area of 25.0mm2 (Cv 1.40) with a max frequency of 4 cycles per second.
No, it switches itself from one DC24V coil signal. By factory default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. Note that the 5/2 valve does not lock the load without live air pressure.
