Airtac SAIF Series Standard Cylinder with Valve SAIF50X150-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X150-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 150mm 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 SAIF50X150-06A
The AirTAC SAIF50X150-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Equipped with a 1/8" valve port, this built-in valve provides an effective flow area of 14.0 mm2 (Cv 0.78) and supports a maximum switching frequency of 5 cycles per second. Driven by an AC220V terminal-entry coil that consumes 3.5 VA, it activates in 0.05 seconds or less under IP65 protection. Because the manifold relies on internal pilot pressure, the practical operating range for this assembled unit is 0.15-0.8 MPa, despite the bare cylinder rating of 1.0 MPa.
This 50mm bore generates 982N of push force and 825N of pull force at 0.5 MPa, making it robust enough for general automation tasks. The manifold connects to the cylinder via PU tubing (O8 x O5), meaning the 1/4" cylinder port and the 1/8" valve port serve distinct roles in the air circuit. Factory-set to retract the piston rod when the coil is energised, the valve can be repositioned to extend-when-energised if your sequence demands it. This decentralized design eliminates remote plumbing, saving panel space.

| 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 SAIF50X150-06A Is Used
Decentralized Stations
Eliminates the need for a remote valve bank, allowing independent control of multiple cylinders across a large machine using a single AC220V signal per station.
Space-Tight Machinery
The integrated 4M210-06 valve manifold saves valuable panel and footprint space in compact assembly cells while delivering 982N of push force.
Retrofit Installations
Perfect for upgrading older lines where routing new pneumatic tubing back to a central control cabinet is impractical, relying instead on direct electrical wiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X150-06A the Right Choice?
Choose this 50mm bore when your application requires around 982N of thrust at 0.5 MPa; stepping down to a 40mm bore yields 628N, while moving up to a 63mm bore provides 1559N. A self-valved SAIF50X150-06A is ideal for decentralized stations where running separate valve tubing would be costly or space-prohibitive. The integrated AC220V terminal coil simplifies wiring compared to grommet variants. Remember that the 5/2 valve routes air but does not lock the load—without live pressure, the cylinder cannot hold position. For true mechanical holding, consider the SAIL lock series. When replacing this unit, verify the 50mm bore, 150mm stroke, 1/8" valve port, AC220V voltage, terminal entry, PT threads, and absence of a 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 SAIF50X150-06A FAQ
The 50mm bore generates 982N push and 825N pull force at 0.5 MPa. The built-in 4M210-06 valve has a 1/8" port with an effective area of 14.0 mm2 (Cv 0.78) and a max frequency of 5 cycles/sec.
No, the integrated 5/2 solenoid valve switches the cylinder directly from an AC220V terminal connection. By default, the rod retracts when the coil is energised, but the valve can be repositioned to extend-when-energised.
