Airtac SAIF Series Standard Cylinder with Valve SAIF50X175S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X175S-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 175mm 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 SAIF50X175S-06A
The AirTAC SAIF50X175S-06A is a double-acting ISO 15552 profile cylinder with an integrated 4M210-06 5/2 solenoid valve. This built-in valve delivers a Cv of 0.78 and routes air directly via PU tubing, eliminating the need for a separate remote valve. The unit is supplied with a PT1/8 cylinder port, a PT1/8 valve port, and a carbon steel piston rod. Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic solid-state sensors for precise position feedback. Driven by an AC220V terminal connection coil consuming 3.5 VA, it achieves IP65 protection and a 0.05s activation time.
While the cylinder body itself rates to 1.0 MPa, the integrated 5/2 valve operates from 0.15 to 0.8 MPa, making the practical working range for the assembled SAIF unit 0.15-0.8 MPa. At 0.5 MPa, this 50mm bore generates 982N of push force and 825N of pull force. By default, the factory setting retracts the piston rod when the coil is energised; this can be reconfigured to extend-when-energised simply by repositioning the valve. This decentralized design requires only one coil signal to drive the cylinder, saving significant panel space and plumbing.

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 SAIF50X175S-06A Is Used
Decentralized Automation Cells
Install multiple self-valved cylinders across a large machine without the tubing complexity of a central panel, driving each station independently via an AC220V signal.
Space-Constrained Machinery
Save valuable panel and footprint space by mounting the 4M210-06 valve directly on the cylinder profile, ideal for tight equipment layouts.
Retrofit & Upgrades
Upgrade older machines by replacing a standard cylinder and remote valve setup with this all-in-one unit, cutting down on pneumatic tubing and wiring labor.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X175S-06A the Right Choice?
Choose this self-valved SAIF50X175S-06A when your machine layout benefits from decentralized control rather than running long air lines back to a central manifold. Stepping down to a 40mm bore drops the 0.5 MPa push force to 628N, while stepping up to a 63mm bore increases it to 1559N. This model uses an AC220V terminal entry coil; if your control system requires DC power, select the B (DC24V) voltage code instead. For exact replacements, match the 50mm bore, 175mm stroke, 06 (1/8") valve port, AC220V voltage, terminal entry, PT thread, and the -S magnet. The 5/2 valve routes air but does not lock the load; if your application requires true mechanical load-holding, consider the AirTAC SAIL pneumatic lock cylinder instead.
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-06A FAQ
At 0.5 MPa, this 50mm bore cylinder generates 982N of push force and 825N of pull force. The built-in 4M210-06 5/2 solenoid valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
Yes. By factory default, the piston rod retracts when the AC220V coil is energised. By physically repositioning the valve on the manifold block, you can reconfigure the action to extend-when-energised. Because the 5/2 valve holds its position via internal pilot pressure, no separate remote valve is needed.
