Airtac SAIF Series Standard Cylinder with Valve SAIF50X450-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X450-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 450mm stroke and a built-in 4M210-06 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 SAIF50X450-06A
The AirTAC SAIF50X450-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This built-in valve provides an effective flow area of 14.0 mm2 (Cv 0.78) and operates at 5 cycles per second. Equipped with a standard AC220V terminal connection coil, it consumes 3.5 VA and features IP65 protection with a rapid 0.05 s activation time. The assembly operates within a practical 0.15-0.8 MPa pressure range, delivering 982 N of push force at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. The manifold connects to the cylinder via PU tubing (O8 x O5), meaning the 1/8 valve port differs from the cylinder's 1/4 port. This self-switching design eliminates the need for remote plumbing, saving panel space and making it perfect for decentralized stations across large machines.

| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAIF50X450-06A Is Used
Decentralized Automation
Eliminates the need for long air lines back to a central manifold, allowing independent station control across large factory layouts.
Compact Machinery
Saves valuable panel and footprint space by integrating the 5/2 valve directly onto the ISO 15552 profile cylinder body.
Retrofit Projects
Ideal for upgrading existing machines where routing new valve tubing is costly or physically constrained.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X450-06A the Right Choice?
Choose this 50 mm bore when you need 982 N push force at 0.5 MPa; step down to a 40 mm bore for 628 N, or up to a 63 mm bore for 1559 N if your load demands it. The self-valved SAIF50X450-06A outperforms a separate cylinder and remote valve setup by drastically reducing wiring and tubing, which is highly advantageous for decentralized machine layouts. Because the stroke is 450 mm, ensure you provide adequate guide support to prevent excessive side loading on the rod.
This specific configuration uses an AC220V terminal entry coil with PT threaded ports. Note that while the cylinder body rates to 1.0 MPa, the integrated 4M210 valve limits the practical working pressure to 0.15-0.8 MPa. The 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL or BSAI series instead. When ordering a replacement, match the 50 mm bore, 450 mm stroke, 1/8 valve port, AC220V voltage, terminal entry, PT thread, and no magnet.
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 SAIF50X450-06A FAQ
The 50 mm bore generates 982 N of push force and 825 N of pull force at 0.5 MPa. The integrated 4M210-06 valve has a 14.0 mm2 orifice with a Cv of 0.78.
No, it has a built-in 4M210 5/2 valve. By default, the rod retracts when the AC220V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
