Airtac SAIF Series Standard Cylinder with Valve SAIF50X500S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X500S-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 SAIF50X500S-06B
The AirTAC SAIF50X500S-06A is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, yielding a Cv of 0.78. Driven by a DC24V terminal coil drawing 3.0W, it eliminates the need for a separate remote valve. Because the cylinder body rates to 1.0 MPa but the integrated valve operates safely at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. It delivers 982N of push force at 0.5 MPa.
Factory configured to retract the piston rod when the coil is energized, it can be reconfigured to extend-when-energized simply by repositioning the valve. The manifold connects to the cylinder via O8xO5 PU tubing, meaning the 1/8" valve port and the 1/4" cylinder port are distinct. Equipped with a magnet for CMSE and DMSE sensors, it enables decentralized machine stations without extensive plumbing.

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 SAIF50X500S-06B Is Used
Decentralized Stations
Ideal for large machines with decentralized stations, driving the 500mm stroke directly from one coil signal without a remote valve bank.
Space-Tight Machinery
Fits compact machinery where running separate valve tubing consumes valuable envelope space, offering integrated 5/2 valve control.
Retrofit Installations
Perfect for retrofits where adding pneumatic tubing is costly, requiring only a DC24V electrical connection to actuate the load.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X500S-06B the Right Choice?
Choose this 50mm bore if you need 982N push force at 0.5 MPa; stepping down to a 40mm bore yields 628N, while stepping up to a 63mm bore provides 1559N. A self-valved SAIF beats a separate cylinder plus remote valve when panel space is tight and running tubing is costly, as one DC24V coil signal switches the unit directly.
For the 500mm stroke, add external guide rails to prevent side-load damage and premature seal wear. The 5/2 valve routes air but does not lock the load—use AirTAC SAIL for positive holding. To replace this unit, match the 50mm bore, 500mm stroke, 1/8" valve port, DC24V terminal entry, PT thread, and -S 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 SAIF50X500S-06B FAQ
The 50mm bore generates 982N push force and 825N pull force at 0.5 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) with a max frequency of 5 cycles/sec.
It uses a DC24V terminal coil (3.0W, IP65, 0.05s response). By factory default, the rod retracts when the coil is energized, but you can reposition the valve to extend-when-energized. No separate valve is needed.
