Airtac SAIF Series Standard Cylinder with Valve SAIF50X600S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X600S-08B 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 SAIF50X600S-08B
The AirTAC SAIF50X600S-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W, it delivers a 982N push force at 0.5 MPa. The integrated manifold routes air via an O8xO5 PU tube, meaning you only need one electrical signal to actuate the cylinder. This decentralized design eliminates remote plumbing and saves panel space. The base cylinder rates to 1.0 MPa, but the practical operating range for this valved assembly is 0.15-0.8 MPa.
Equipped with a magnet for position sensing, this unit works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 valve holds its position by internal pilot pressure, not a spring. It is not a lock; for load-holding duties, consider the SAIL or BSAI series instead.

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 SAIF50X600S-08B Is Used
Decentralized Automation Stations
Ideal for large machines with distributed stations, eliminating long pneumatic tubing runs by switching the cylinder directly at the point of use.
Material Handling Diverter
Provides reliable 982N push force for diverting products on a 600mm stroke, with the built-in valve simplifying control wiring.
Space-Constrained Machinery
Saves valuable panel space by removing the need for a remote valve island, using only a DC24V signal to drive the actuator.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X600S-08B the Right Choice?
Choose this 50mm bore if your application requires around 982N push force at 0.5 MPa. If you need less force, stepping down to a 40mm bore yields 628N push; if you need more, a 63mm bore provides 1559N. The SAIF50X600S-08B is ideal for decentralized stations where running separate valve tubing is costly or space-prohibitive. The DC24V terminal coil offers IP65 protection and a 0.05s response time. The valve port is 1/4 inch (code 08) with PT tapered threads, while the cylinder port is also PT1/4. Because the 600mm stroke is substantial, ensure adequate guiding to prevent excessive side loads on the rod. When ordering a replacement, confirm the 50mm bore, 600mm stroke, 4M210-08 valve, DC24V voltage, terminal entry, PT threads, and the -S magnet.
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 SAIF50X600S-08B FAQ
The 50mm bore generates a 982N push force and 825N pull force at 0.5 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice with a Cv of 0.89.
The DC24V coil energizes the 5/2 valve, which routes air internally via PU tubing. By default, the rod retracts when energized, but you can reposition the valve to extend instead. The valve holds its position via pilot pressure, not a spring, so it does not lock the load; use SAIL or BSAI for load holding.
