Airtac SAIF Series Standard Cylinder with Valve SAIF50X700S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X700S-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 700mm 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 SAIF50X700S-08A
The AirTAC SAIF50X700S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This integrated valve delivers a 16.0 mm2 effective area (Cv 0.89) and operates at 5 cycles per second. Equipped with an AC220V terminal coil drawing 3.5 VA, it activates in 0.05 seconds. While the cylinder body rates to 1.0 MPa, the practical operating range for this valved unit is 0.15-0.8 MPa. The 50 mm bore generates 982 N 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-when-energised by repositioning the valve. This self-switching design eliminates the need for a remote valve, saving panel space and tubing. The manifold connects to the cylinder via an O8 x O5 PU tube, and the valve port (1/4") differs from the cylinder port (1/4"). The -S magnet works with CMSE reed and DMSE electronic sensors for precise position feedback.

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 SAIF50X700S-08A Is Used
Decentralized Assembly Lines
Perfect for large machines with multiple stations, eliminating long tubing runs by controlling the cylinder directly from its integrated AC220V coil.
Space-Constrained Machinery
The built-in 4M210-08 valve saves valuable panel and footprint space, delivering 982 N of push force in a compact ISO 15552 profile.
Retrofit Automation
Ideal for upgrading older equipment where adding a remote valve bank is impractical, using the existing 700 mm stroke and terminal wiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X700S-08A the Right Choice?
Choose this 50 mm bore when your application requires around 982 N of push force at 0.5 MPa. If you need less force, step down to the 40 mm bore (628 N push); if you need more, step up to the 63 mm bore (1559 N push). The SAIF50X700S-08A is ideal for decentralized stations where running separate valve tubing is costly or space-prohibitive. It includes a 700 mm stroke, a 4M210-08 valve with PT1/4 ports, an AC220V terminal coil, and a magnet for CMSE/DMSE sensors. Because the stroke is 700 mm, ensure you provide adequate guide support to prevent excessive side loading on the rod. Note that the 5/2 valve routes air but does not hold the load without live pressure; for true load-holding, consider the SAIL lock cylinder.
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 SAIF50X700S-08A FAQ
The 50 mm bore generates 982 N of push force and 825 N of pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89) and supports a max frequency of 5 cycles per second.
No, the SAIF50X700S-08A switches itself from a single AC220V coil signal. By factory default, the rod retracts when energised, but you can reposition the valve to extend-when-energised. This eliminates remote valves and reduces plumbing.
