Airtac SAIF Series Standard Cylinder with Valve SAIF50X500-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X500-06A 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 SAIF50X500-06A
The AirTAC SAIF50X500-06A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. This integrated valve provides an effective flow area of 14.0 mm2 (Cv 0.78) and operates at a maximum frequency of 5 cycles per second. Supplied with an AC220V coil consuming 3.5 VA, it uses a terminal electrical entry with PT tapered threads. The manifold connects to the cylinder bore using an O8 x O5 PU tube, ensuring rapid self-switching without remote plumbing.
While the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. At 0.5 MPa it delivers 982 N of push force and 825 N of pull force. By default, the piston rod retracts when the coil is energised, but you can reconfigure the valve to extend-when-energised by repositioning it. This decentralized design requires only one coil signal to drive the motion, saving panel space.

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.

| 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 SAIF50X500-06A Is Used
Decentralized Assembly Stations
Eliminates the need for remote valve banks on large machines by switching directly at the cylinder, saving wiring and plumbing space.
Material Handling Diverters
Provides 982 N of push force at 0.5 MPa to actuate sorting gates, relying on the built-in 4M210 valve for rapid 5 cycle/sec operation.
Space-Constrained Retrofits
Ideal for upgrading older pneumatic lines where adding external valves is impractical, using a single AC220V terminal signal to control motion.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X500-06A the Right Choice?
Choose this 50mm bore when your application requires around 982 N of push force at 0.5 MPa; stepping down to a 40mm bore yields 628 N, while a 63mm bore provides 1559 N. The SAIF50X500-06A is ideal for decentralized stations where running separate valve tubing is costly, as the integrated 4M210 valve handles switching directly on the cylinder. It uses an AC220V terminal connection and a PT1/8 valve port.
When specifying this 500mm stroke, note that longer strokes increase susceptibility to side loads; always use a guide to prevent rod damage. The 5/2 valve routes air but does not lock the load, so for position holding you need a SAIL lock cylinder. To replace this unit, match the 50mm bore, 500mm stroke, 1/4" cylinder port, 06 (1/8") valve port, AC220V terminal coil, 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 SAIF50X500-06A FAQ
The 50mm bore provides 982 N push and 825 N pull force at 0.5 MPa. The built-in 4M210-06 valve has a 14.0 mm2 orifice (Cv 0.78) and supports up to 5 cycles per second.
No, the 5/2 valve routes air but does not lock the load. The factory setting retracts the rod when the AC220V coil is energised, but it can be repositioned to extend-when-energised. For true load holding, consider a SAIL lock cylinder.
