Airtac SAIF Series Standard Cylinder with Valve SAIF50X300S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X300S-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 300mm 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 SAIF50X300S-06A
The AirTAC SAIF50X300S-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by an AC220V terminal entry coil drawing 3.5 VA, it delivers a 982N push force at 0.5 MPa. The built-in valve has a 14.0 mm2 orifice (Cv 0.78) and cycles up to 5 times per second. Because the valve manifold mounts directly using O8 x O5 PU tubing, it eliminates remote plumbing and saves panel space for decentralized machine stations.
The base cylinder body rates to 1.0 MPa, but the practical operating range for this valved assembly is 0.15-0.8 MPa. Factory configured to retract the rod when the coil is energised, the valve can be repositioned to extend on signal instead. This 300mm stroke unit includes a magnet for CMSE reed and DMSE electronic sensors, operating at speeds of 30-800 mm/s without requiring lubrication.

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)

| 0.7 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 SAIF50X300S-06A Is Used
Decentralized Stations
Ideal for large assembly lines where installing a local AC220V coil signal avoids running long pneumatic tubing back to a main control panel.
Mid-Stroke Positioning
The 300mm stroke and 982N force suit automated gating and mid-length part pushing tasks that require integrated self-switching.
Retrofit Upgrades
Drops into existing ISO 15552 footprints to add a built-in 4M210 valve, reducing overall plumbing complexity in space-tight machinery.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X300S-06A the Right Choice?
Choose this self-valved SAIF unit when decentralizing automation across a large machine, as routing a single AC220V electrical signal is far simpler than running pneumatic tubing back to a central manifold. If your application requires less force, stepping down to a 40mm bore yields 628N push at 0.5 MPa; stepping up to a 63mm bore provides 1559N. Note that the 1/4 inch cylinder port and 1/8 inch valve port are distinct, and the carbon steel rod uses a PT tapered thread.
For this 300mm stroke, ensure adequate side-load protection by using a guide rail to prevent rod binding. The 5/2 valve routes air but does not lock the load mechanically—use an AirTAC SAIL lock cylinder if static holding is required. To replace this unit, match the 50mm bore, 300mm stroke, -S magnet, 06 valve port, AC220V terminal coil, PT thread, and ISO 15552 mounting interface.
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 SAIF50X300S-06A FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982N of push force and 825N of pull force. The integrated 4M210-06 5/2 valve has an effective flow area of 14.0 mm2 (Cv 0.78).
By factory default, the rod retracts when the coil is energised. Because it uses a 5/2 pilot valve rather than a spring, you can reposition the valve on the manifold to make it extend when energised instead.
