Airtac SAIF Series Standard Cylinder with Valve SAIF50X1000-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X1000-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 1000mm 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 SAIF50X1000-08A
The AirTAC SAIF50X1000-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89. Driven by an AC220V terminal coil consuming 3.5 VA, it eliminates the need for a separate remote valve. The cylinder body rates to 1.0 MPa, but because the integrated valve operates at 0.15-0.8 MPa, the practical working range for the assembled SAIF unit is 0.15-0.8 MPa.
This 50mm bore unit generates 1767N of push force at 0.9 MPa and uses an O8xO5 PU tube to bridge the manifold block. By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 valve holds its position via internal pilot pressure, not a spring, though it cannot hold a load without live air pressure.

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 SAIF50X1000-08A Is Used
Decentralized Stations
Ideal for large machines with distributed stations, allowing a single coil signal to actuate the cylinder without running long valve tubing back to a central panel.
Space-Tight Machinery
The integrated manifold block saves valuable footprint in compact assemblies where mounting a separate valve and cylinder is physically impractical.
Long-Stroke Handling
Suited for 1000mm stroke material handling tasks, provided external guide supports are used to manage side-loads on the extended rod.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X1000-08A the Right Choice?
Choose this self-valved SAIF configuration when installing decentralized stations across a large machine, as it saves panel space and plumbing compared to running separate valve tubing. If your application requires less force, the 40mm neighbor provides 1130N push at 0.9 MPa; for higher loads, step up to the 63mm bore offering 2805N. This specific SKU specifies a 1000mm stroke, which exceeds the 50mm bore's 1200mm standard maximum, making it a non-standard stroke. For any stroke of 300mm or greater, you must account for side-load and use appropriate guide rails to prevent rod binding. To replace this unit, match the 50mm bore, 1000mm stroke, 1/4" valve port, AC220V terminal coil, 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 SAIF50X1000-08A FAQ
The 50mm bore generates 1767N of push force at 0.9 MPa. The built-in 4M210-08 valve provides an effective flow area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
It uses a 5/2 solenoid valve that holds position via internal pilot pressure. By default, the rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised. This unit uses an AC220V terminal entry coil, though AC110V, AC24V, DC24V, and DC12V are also available.
