Airtac SAIF Series Standard Cylinder with Valve SAIF50X160-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X160-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 160mm 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 SAIF50X160-08A
The AirTAC SAIF50X160-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This built-in valve provides a Cv of 0.89 and routes air directly through a manifold block via O8xO5 PU tubing, eliminating the need for separate remote valves. Driven by an AC220V terminal connection coil consuming 3.5 VA with an IP65 rating, it delivers 982N of push force at 0.5 MPa and reaches a maximum frequency of 5 cycles per second.
Because the 4M210 valve operates between 0.15-0.8 MPa, the practical working pressure for this assembled SAIF unit is 0.15-0.8 MPa, even though the bare cylinder body rates to 1.0 MPa. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-contained design requires only a single electrical signal to drive the motion, making it highly effective 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)

|---|---|---|
| 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 SAIF50X160-08A Is Used
Decentralized Assembly Stations
Eliminates remote valve banks by controlling the cylinder directly from a single AC220V signal, reducing panel space and plumbing complexity across large factory layouts.
Space-Constrained Machinery
The integrated 4M210-08 valve and manifold block save valuable envelope space, making it perfect for compact packaging and testing equipment where external tubing is impractical.
Machine Retrofitting
Ideal for upgrading existing lines where adding long runs of valve tubing is costly; the terminal entry and PT1/4 ports allow for quick electrical and pneumatic hookups.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X160-08A the Right Choice?
Choose this 50mm bore when your application requires around 982N push force at 0.5 MPa; if you need less force, step down to a 40mm bore (628N push), or step up to a 63mm bore (1559N push) for heavier loads. The SAIF50X160-08A with its AC220V terminal coil and PT1/4 cylinder port is ideal for space-tight machines where running separate valve tubing is costly. The 160mm stroke is well within standard limits, but always ensure adequate guide support to handle side loads. To replace this unit, match the 50mm bore, 160mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT thread, and no magnet (-S).
Remember that the integrated 5/2 valve routes air but does not lock the load; if your process requires position holding without live pressure, consider the AirTAC SAIL lock cylinder or BSAI clamp-lock series instead. The air cushions only decelerate the piston near the stroke ends.
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 SAIF50X160-08A FAQ
The 50mm bore cylinder provides 982N of push force and 825N of pull force at 0.5 MPa. The built-in 4M210-08 5/2 solenoid valve has an effective area of 16.0 mm2 (Cv 0.89) and supports a maximum no-load frequency of 5 cycles per second.
The built-in valve allows the cylinder to control itself from one coil signal, saving panel space and tubing for decentralized installations. By factory default, the rod retracts when the AC220V coil is energised, but you can reposition the valve to extend-when-energised if needed.
