Airtac SAIF Series Standard Cylinder with Valve SAIF50X800S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X800S-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 800mm 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 SAIF50X800S-06B
The AirTAC SAIF50X800S-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal entry coil drawing 3.0 W, a PT1/8 valve port, and a standard PT1/4 cylinder port. The built-in valve provides a Cv of 0.78 (14.0 mm2 effective area) and switches at up to 5 cycles per second. Because the manifold bridges the valve and cylinder using an O8 x O5 PU tube, you save panel space and eliminate remote plumbing. The -S suffix indicates a piston magnet for position sensing with CMSE reed or DMSE electronic switches.
Although the cylinder body rates to 1.0 MPa, the practical operating pressure for the assembled SAIF unit is 0.15-0.8 MPa due to the valve limits. In its factory setting, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence requires it. Operating speed spans 30-800 mm/s. At 0.5 MPa this 50 mm bore generates 982 N of push force and 825 N of pull force, making it robust enough for heavy lifting without needing a separate directional control valve.

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)

| 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 SAIF50X800S-06B Is Used
Decentralized Conveyor Diverters
Eliminates the need to run long air tubes back to a central manifold. The integrated DC24V valve switches the 800 mm stroke directly at the station.
Space-Constrained Machinery
Saves valuable panel space by mounting the 4M210-06 valve directly on the cylinder profile, ideal for compact assembly cells.
Retrofit Automation Upgrades
Drops into existing ISO 15552 mounting footprints. The -S magnet allows easy addition of CMSE or DMSE sensors for stroke confirmation.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X800S-06B the Right Choice?
Choose this 50 mm bore when you need the 982 N push force at 0.5 MPa; stepping down to a 40 mm bore drops push force to 628 N, while stepping up to a 63 mm bore yields 1559 N. The 800 mm stroke falls within the 1200 mm standard maximum for this bore. For any stroke at or above 300 mm, you must account for side loads—use a guide rail or pivot mount to prevent rod binding and premature seal wear. This self-valved SAIF configuration is superior to a separate cylinder and remote valve when wiring and air tubing runs are costly, as it requires only a single DC24V electrical signal to operate. Remember that the 5/2 valve routes air but does not lock the load; if you need true load holding on a vertical 800 mm lift, consider an AirTAC SAIL lock cylinder instead.
When ordering a replacement, verify the exact configuration: 50 mm bore, 800 mm stroke, valve port code 06 (PT1/8), DC24V voltage, terminal electrical entry, PT thread standard, and the -S magnet option. The carbon steel piston rod provides standard durability for general pneumatic automation.
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 SAIF50X800S-06B FAQ
At 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. The integrated 4M210-06 valve has a 14.0 mm2 effective area (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
No, the built-in 5/2 solenoid valve controls the cylinder directly from a DC24V signal. By factory default, energising the coil retracts the rod, but the valve can be repositioned to extend-when-energised. Note that the valve routes air and does not hold the load without live pressure.
