Airtac SAIF Series Standard Cylinder with Valve SAIF50X900S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X900S-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 900mm 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 SAIF50X900S-06A
The AirTAC SAIF50X900S-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This specific configuration uses a PT1/8 valve port (Cv 0.78, 14.0 mm2 orifice) and a PT1/4 cylinder port, linked internally via O8xO5 PU tubing. Driven by an AC220V terminal entry coil drawing 3.5 VA, it activates in 0.05 s or less. The 50 mm bore generates 982 N of push force at 0.5 MPa, scaling up to 1374 N at 0.7 MPa. A factory-installed magnet (-S) enables position detection with AirTAC CMSE reed or DMSE electronic sensors.
Because the cylinder body rates to 1.0 MPa but the built-in valve operates safely between 0.15 and 0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The valve is factory-set to retract the rod when the coil is energised, though you can reposition it to extend-when-energised. By switching itself from a single coil signal, it eliminates the need for a separate remote valve, saving panel space and making it ideal 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)

| 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 SAIF50X900S-06A Is Used
Decentralized Stations
Eliminates long tubing runs to a central panel by switching locally via the AC220V terminal coil, simplifying wiring on large 900 mm stroke assemblies.
Long-Stroke Diverters
Provides 982 N push force at 0.5 MPa for diverting products, with the built-in 4M210 valve ensuring rapid 0.05 s response without remote plumbing lag.
Space-Tight Machinery
Saves valuable panel space by mounting the 5/2 valve directly on the ISO 15552 profile body, ideal for compact automated cells.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X900S-06A the Right Choice?
Choose this self-valved SAIF configuration when plumbing a remote valve to a 900 mm stroke cylinder would require long, restrictive tubing runs. The integrated 4M210 valve supports a maximum frequency of 5 cycles per second. If your application requires higher thrust, stepping up to the 63 mm bore yields 1559 N at 0.5 MPa; if less force is needed, the 40 mm bore provides 628 N. For this 900 mm stroke, adding an external guide is critical to prevent excessive side-loading on the rod and seal wear. The carbon steel rod standard on this unit handles general industrial loads well.
When ordering a replacement, confirm the 50 mm bore, 900 mm stroke, PT1/8 valve port, AC220V voltage, and terminal electrical entry. The -S suffix indicates the piston magnet is present for CMSE / DMSE sensors. Remember that the 5/2 valve routes air but does not lock the load mechanically; if you need true load-holding, consider the SAIL lock variant 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 SAIF50X900S-06A FAQ
The 50 mm bore generates 982 N of push force and 825 N of pull force at 0.5 MPa. The integrated 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and supports up to 5 cycles per second.
The 5/2 valve routes air but does not mechanically lock the load; for holding you need a SAIL lock cylinder. Factory-set to retract when energised, the valve can be repositioned on the manifold to extend-when-energised, and it requires no separate remote valve to operate.
