Airtac SAIF Series Standard Cylinder with Valve SAIF50X300-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X300-06A 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 SAIF50X300-06A
The AirTAC SAIF50X300-06A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This built-in valve provides an effective flow area of 14.0 mm2 (Cv 0.78) and operates at a maximum frequency of 5 cycles per second. Driven by an AC220V terminal connection coil consuming 3.5 VA, it activates in 0.05 seconds or less. The cylinder itself features a 1/8 PT port, while the valve utilizes a 1/8 port connected via an O8 x O5 PU tube manifold block.
Although the cylinder body rates to 1.0 MPa, the practical operating range for this assembled SAIF unit is 0.15-0.8 MPa due to the internal pilot valve limits. At 0.5 MPa, it delivers 982 N of push force and 825 N of pull force. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. It switches itself from a single coil signal, eliminating remote valves and reducing panel space for decentralized machine stations.

| 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 SAIF50X300-06A Is Used
Decentralized Machine Stations
Ideal for large machines where running individual valve lines is costly, this self-valved cylinder operates independently from a single AC220V signal.
Space-Tight Assembly Automation
Eliminates the need for a separate remote valve and manifold block, saving critical panel and footprint space in compact automated equipment.
Retrofit & Upgrades
Perfect for upgrading existing ISO 15552 profile cylinder setups by integrating the 5/2 valve directly onto the unit, simplifying future maintenance.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X300-06A the Right Choice?
Select this 50mm bore when your application requires around 982 N of push force at 0.5 MPa. If you need less force, stepping down to a 40mm bore provides 628 N push force, while stepping up to a 63mm bore yields 1559 N. The self-valved SAIF50X300-06A excels over a separate cylinder and remote valve in space-tight machines or retrofits where running tubing is costly. With a 300mm stroke, you must account for potential side loads and use a proper guide to prevent rod binding.
This configuration uses an AC220V terminal entry and a PT threaded 1/8 valve port. Note that the 5/2 valve routes air but does not hold the load without live pressure; it is not a lock. For position holding, consider the SAIL lock or BSAI clamp-lock series. When ordering a replacement, match the 50mm bore, 300mm stroke, 06 valve port, AC220V voltage, terminal entry, PT thread, and no magnet (-S).
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 SAIF50X300-06A FAQ
The 50mm bore 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.
Yes, the SAIF50X300-06A has a built-in 5/2 solenoid valve, so it switches itself from one AC220V coil signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
