Airtac SAIF Series Standard Cylinder with Valve SAIF50X600-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X600-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 600mm stroke and a built-in 4M210-08 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 SAIF50X600-08A
The AirTAC SAIF50X600-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific SKU is configured with a 1/4" PT valve port, an AC220V coil drawing 3.5 VA, and a terminal electrical entry. The built-in valve provides an effective flow area of 16.0 mm2 (Cv 0.89) and cycles up to 5 times per second. Because the cylinder itself is rated for 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working pressure range for this assembled unit is 0.15-0.8 MPa.
Generating 982 N of push force at 0.5 MPa, this 50 mm bore unit eliminates the need for separate remote valves and extensive tubing. The valve manifold connects to the cylinder via O8 x O5 PU tubing, meaning the 1/4" valve port and the 1/4" cylinder port serve distinct routing paths. Factory-set to retract the rod when the coil is energised, the valve can be repositioned on the manifold to extend-when-energised if your machine logic requires it. This decentralized architecture drives the cylinder from a single coil signal, saving significant panel space.

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 SAIF50X600-08A Is Used
Decentralized Machine Stations
Ideal for large machinery where routing air lines back to a central valve bank is costly. The integrated AC220V valve handles switching locally.
Extended Stroke Diverters
The 600 mm stroke provides long travel for pushing products between conveyor lanes without needing a separate cylinder and valve assembly.
Compact Assembly Cells
Saves valuable panel and floor space by mounting the 4M210-08 valve directly to the cylinder, simplifying wiring and pneumatic plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X600-08A the Right Choice?
Choose this self-valved SAIF50X600-08A when a decentralized station needs 982 N of push force at 0.5 MPa without the plumbing of a remote valve bank. If your application requires less force, the 40 mm bore neighbour offers 628 N push at 0.5 MPa; stepping up to the 63 mm bore yields 1559 N. The 600 mm stroke on this profile cylinder demands careful attention to side loads—ensure adequate external guiding to prevent rod binding and premature seal wear over the long travel distance.
This assembly is specified by its complete bundle: a 50 mm bore, 600 mm stroke, 1/4" valve port, AC220V voltage, terminal entry, and PT thread. The integrated 5/2 valve routes air internally, but it does not lock or hold the load without live air pressure. For position-holding requirements, consider the SAIL pneumatic lock series instead. This unit ships without a magnet (-S not specified), so position sensing is not supported out of the box.
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 SAIF50X600-08A FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. The maximum push force is 1767 N at 0.7 MPa.
Yes. The factory default setting retracts the piston rod when the AC220V coil is energised. By repositioning the 4M210-08 valve on the manifold block, you can reconfigure it to extend when energised. No separate remote valve is needed.
