Airtac SAIF Series Standard Cylinder with Valve SAIF50X350-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X350-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 350mm 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 SAIF50X350-06A
The AirTAC SAIF50X350-06A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. This integrated valve delivers a 14.0 mm2 effective area (Cv 0.78) and operates at a maximum frequency of 5 cycles per second. Driven by an AC220V terminal-connected coil drawing 3.5 VA, it activates in 0.05 seconds. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled unit, even though the cylinder body rates to 1.0 MPa. The 50mm bore generates 982N of push force at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend upon energising by repositioning the valve. The manifold links the valve to the cylinder using O8 x O5 PU tubing, meaning the 1/8" valve port and 1/4" cylinder port are distinct. This self-switching design eliminates remote plumbing, saving panel space for decentralized stations 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)
| 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 SAIF50X350-06A Is Used
Decentralized Stations
Ideal for large machines where running valve tubing is costly, using one AC220V signal to drive the 982N cylinder directly.
Space-Tight Machines
The built-in 4M210 valve eliminates the panel space needed for a remote valve, streamlining the 350mm stroke assembly.
Wiring Retrofits
Perfect for upgrades where adding a centralized valve bank is impractical, leveraging the 0.05s terminal coil response.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X350-06A the Right Choice?
Choose this 50mm bore when you need around 982N push force at 0.5 MPa; step down to a 40mm bore for 628N if space is tight, or up to a 63mm bore for 1559N in heavier tasks. A self-valved SAIF beats a separate cylinder plus remote valve when you want to minimize tubing and wiring across decentralized machine stations. For this 350mm stroke, add an external guide to prevent side-load damage. Remember, the 5/2 valve routes air but does not lock the load; use an AirTAC SAIL lock cylinder for position holding. Replacement requires matching the 50mm bore, 350mm stroke, 1/8" valve port, AC220V terminal coil, PT threads, and no 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 SAIF50X350-06A FAQ
The 50mm bore generates 982N push force at 0.5 MPa. The built-in 4M210-06 valve has a 14.0 mm2 orifice (Cv 0.78) and handles up to 5 cycles per second.
No separate valve is needed. The factory setting retracts the rod when the AC220V coil energises, but you can reconfigure it to extend-when-energised by repositioning the valve.
