Airtac SAIF Series Standard Cylinder with Valve SAIF50X80S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X80S-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 80mm 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 SAIF50X80S-06B
The AirTAC SAIF50X80S-06B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. This integrated assembly delivers a Cv of 0.78 and operates on a DC24V terminal coil drawing 3.0 W. Because the cylinder body rates to 1.0 MPa but the internal pilot valve limits to 0.15-0.8 MPa, the practical working pressure for the assembled unit is 0.15-0.8 MPa. It provides 982 N of push force at 0.5 MPa.
By switching itself from a single coil signal, it eliminates remote plumbing and saves panel space for decentralized machine stations. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. The manifold uses an O8 x O5 PU tube, and the valve port (1/8) differs from the cylinder port (1/4). A magnet is included for CMSE reed and DMSE electronic sensors.

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 SAIF50X80S-06B Is Used
Decentralized Stations
Ideal for large machines with decentralized stations, eliminating long pneumatic lines by mounting the valve directly on the cylinder.
Space-Tight Machines
Perfect for compact assemblies where panel space is limited, integrating the 4M210-06 valve and cylinder into one unit.
Retrofit Automation
Suits retrofits where running new valve tubing is costly, driving 982 N of push force from a single DC24V signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X80S-06B the Right Choice?
Choose this 50 mm bore when you need 982 N push force at 0.5 MPa; step down to a 40 mm bore for 628 N, or up to a 63 mm bore for 1559 N. A self-valved SAIF is ideal for space-tight machines where running separate valve tubing is costly. This model uses a DC24V terminal connection with PT threads. For exact replacements, match the 50 mm bore, 80 mm stroke, 1/8 valve port, DC24V voltage, terminal entry, and the -S magnet. Stroke is 80 mm, so no external side-load guide is required.
Remember that the built-in 5/2 valve routes air but does not lock the load. The variable air cushion only decelerates near stroke end. For true position holding under pressure loss, select a SAIL pneumatic 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 SAIF50X80S-06B FAQ
At 0.5 MPa, the 50 mm bore provides 982 N of push force and 825 N of pull force. The integrated 4M210-06 valve has a Cv of 0.78 and an orifice of 14.0 mm2.
No, the 4M210-06 5/2 valve mounts directly via a manifold block. It operates on DC24V at 3.0 W. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised.
