Airtac SAIF Series Standard Cylinder with Valve SAIF50X175S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X175S-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 175mm 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 SAIF50X175S-08A
The AirTAC SAIF50X175S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, it delivers a 982N push force at 0.5 MPa. The cylinder body rates to 1.0 MPa, but the built-in valve limits the practical SAIF operating range to 0.15-0.8 MPa. The manifold connects to the barrel using O8xO5 PU tubing, keeping the assembly compact.
By switching itself from a single electrical signal, this unit eliminates remote valves and excess plumbing, making it ideal for decentralized stations across large machines. The factory default retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. The -S magnet supports CMSE reed and DMSE electronic sensors for 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 SAIF50X175S-08A Is Used
Decentralized Automation
Eliminates the need for a remote valve island, allowing independent control of multiple stations across a large machine layout.
Space-Constrained Machinery
The integrated manifold block saves valuable panel and footprint space where running external tubing is impractical.
Retrofit Position Feedback
The built-in -S magnet enables drop-in CMSE or DMSE sensor installation for precise stroke end detection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X175S-08A the Right Choice?
Choose this 50mm bore when you need 982N of push thrust at 0.5 MPa; step down to a 40mm bore for 628N, or up to a 63mm bore for 1559N. A self-valved SAIF beats a separate cylinder and remote valve when panel space is tight and running tubing is costly. The AC220V terminal connection offers IP65 protection and a 0.05s response time. Remember the 5/2 valve routes air but does not lock the load; for position holding, consider an SAIL lock cylinder. To replace this unit, match the 50mm bore, 175mm stroke, PT1/4 cylinder port, 1/4" valve port, AC220V terminal coil, and -S 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 SAIF50X175S-08A FAQ
At 0.5 MPa, the 50mm bore provides 982N of push force and 825N of pull force. The integrated 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89) and a maximum frequency of 5 cycles per second.
No, the integrated 5/2 solenoid valve switches the cylinder directly from the AC220V coil signal. By factory default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
