Airtac SAIF Series Standard Cylinder with Valve SAIF50X450S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X450S-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 SAIF50X450S-06A
The AirTAC SAIF50X450S-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This specific SKU pairs a 50mm bore with a 1/8" valve port, delivering a Cv of 0.78 and a 982N push force at 0.5 MPa. It includes a magnet for CMSE reed and DMSE electronic sensors. Because the valve is mounted directly via a manifold block and O8xO5 PU tubing, it eliminates the need for a separate remote valve, saving panel space and simplifying decentralized installation across large machines.
This model runs on an AC220V terminal connection coil drawing 3.5 VA, with an IP65 rating and a 0.05s activation time. While the cylinder body rates to 1.0 MPa, the practical working pressure is 0.15-0.8 MPa due to the valve's internal pilot limits. By factory default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. Note that the 1/4" cylinder port differs from the 1/8" valve port.

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 SAIF50X450S-06A Is Used
Decentralized Automation Cells
Eliminates remote valve banks by switching locally via the built-in 4M210-06 valve, drastically reducing tubing runs across sprawling factory layouts.
Mid-Thrust Assembly Stations
Provides 982N of push force at 0.5 MPa for clamping and pressing components, using the integrated magnet for DMSE electronic position sensing.
Space-Constrained Retrofits
Ideal for machinery upgrades where panel space is tight, using the AC220V terminal connection to drive the cylinder directly without external manifolds.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X450S-06A the Right Choice?
Choose this self-valved SAIF50X450S-06A when you need to consolidate wiring and plumbing in decentralized stations, stepping up from a 40mm bore (628N push at 0.5 MPa) to gain higher thrust, or down from a 63mm bore (1559N) if 982N is sufficient. The integrated 4M210-06 valve switches itself from one coil signal, which is ideal for space-tight machines where running remote valve tubing is costly. If your application requires true load holding without live pressure, note that this 5/2 valve routes air but does not lock; consider an SAIL clamp cylinder instead.
When replacing this unit, match the 50mm bore, 450mm stroke, 1/8" valve port, AC220V terminal coil, PT thread, and -S magnet. Because the 450mm stroke exceeds 300mm, ensure you use appropriate guide rails to prevent excessive side-loading on the rod. Operating speed ranges from 30-800 mm/s.
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 SAIF50X450S-06A FAQ
At 0.5 MPa, this 50mm bore cylinder delivers a 982N push force and an 825N pull force. The integrated 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) with a maximum frequency of 5 cycles per second.
Yes, by factory default the rod retracts when the AC220V coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The 5/2 valve holds its position via internal pilot pressure, not a spring, so it requires continuous air pressure within the 0.15-0.8 MPa range.
