Airtac SAIF Series Standard Cylinder with Valve SAIF50X50-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X50-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 50mm 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 SAIF50X50-06B
The AirTAC SAIF50X50-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This built-in valve delivers a Cv of 0.78 and operates at a maximum frequency of 5 cycles per second. Equipped with a DC24V terminal coil drawing 3.0 W, it activates in 0.05 seconds or less. The assembly runs at 0.15-0.8 MPa, as the integrated valve limits the 1.0 MPa cylinder pressure rating. Delivering 982 N of push force at 0.5 MPa, it uses a carbon steel rod and PT tapered threads.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The manifold connects to the cylinder via PU tubing (O8 x O5), and the valve port (1/8) differs from the cylinder port (1/4). This decentralized design eliminates remote plumbing, saving panel space and reducing tubing costs across large machines.

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 SAIF50X50-06B Is Used
Decentralized Machine Stations
Ideal for large machines with multiple actuation points, eliminating long air lines from a central valve bank by controlling the cylinder directly at the point of operation.
Compact Assembly Lines
Saves valuable panel and floor space by integrating the 4M210 valve directly onto the cylinder profile, perfect for tight retrofits and dense layouts.
Wiring Simplification
Reduces control complexity by driving the cylinder from a single DC24V terminal coil signal, minimizing wiring harnesses and potential failure points.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X50-06B the Right Choice?
Select this 50 mm bore when your application requires around 982 N push force at 0.5 MPa. If you need less force, stepping down to a 40 mm bore yields 628 N; for heavier loads, a 63 mm bore provides 1559 N. The SAIF50X50-06B is ideal for decentralized stations where running separate valve tubing is costly or space-prohibitive. It switches itself from one DC24V coil signal, removing the need for a remote valve bank.
Remember that the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock series. When ordering a replacement, match the 50 mm bore, 50 mm stroke, 06 valve port, DC24V voltage, terminal entry, PT thread, and lack of a magnet. Because the stroke is under 300 mm, side-load concerns are minimal, but always verify guide alignment.
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 SAIF50X50-06B FAQ
The cylinder provides 982 N of push force and 825 N of pull force at 0.5 MPa. The built-in 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 lock the load without live pressure. By factory default, the rod retracts when the DC24V coil is energised, but you can reposition the valve to extend-when-energised. No separate remote valve is needed.
