Airtac SAIF Series Standard Cylinder with Valve SAIF50X500-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X500-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 500mm 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 SAIF50X500-06B
The AirTAC SAIF50X500-06B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, offering a Cv of 0.78. Driven by a DC24V terminal coil consuming 3.0W with an IP65 rating, it generates 982N of push force at 0.5MPa. The assembled unit operates within a 0.15-0.8MPa range, as the integrated valve limits the cylinder's 1.0MPa maximum. It uses an O8xO5 PU tube between the manifold and cylinder.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. Because it switches itself from one coil signal, no remote valve is needed, saving panel space and reducing plumbing for decentralized machine stations.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF50X500-06B Is Used
Decentralized Stations
Ideal for large machines with decentralized stations, cutting panel space by driving the 500mm stroke directly from the DC24V coil signal.
Space-Tight Machinery
Fits compact assemblies where running remote valve tubing is costly, using the built-in 4M210-06 valve to self-switch the actuator.
Retrofit Automation
Simplifies retrofits by bundling a 982N thrust cylinder and 5/2 valve, minimizing pneumatic plumbing and electrical wiring overhead.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X500-06B the Right Choice?
Choose this 50mm bore when a 40mm cylinder (628N push at 0.5MPa) lacks thrust, but a 63mm bore (1559N) is excessive. The self-valved SAIF50X500-06B outperforms a separate cylinder plus remote valve in space-tight machines by eliminating long tubing runs and external wiring. It uses a PT1/8 valve port and PT1/4 cylinder port. For replacement, verify the 500mm stroke, 06 valve port, DC24V voltage, terminal entry, PT thread, and no magnet (-S).
With a 500mm stroke, use a guide to prevent rod side-load damage and ensure smooth travel. The 5/2 valve routes air but does not lock the load; for position holding, consider an AirTAC SAIL lock cylinder instead.
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 SAIF50X500-06B FAQ
The 50mm bore provides 982N push and 825N pull force at 0.5MPa. The built-in 4M210-06 valve has a 14.0mm2 orifice with a Cv of 0.78.
The 5/2 valve routes air but does not lock the load without live pressure. This model uses a DC24V terminal coil. By default, the rod retracts when energised, but you can reconfigure it to extend by repositioning the valve.
