Airtac SAIF Series Standard Cylinder with Valve SAIF32X175-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X175-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm 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 SAIF32X175-08A
The AirTAC SAIF32X175-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This integrated assembly delivers a Cv of 0.89 and operates at a practical 0.15-0.8 MPa working range, as the valve limits the cylinder's 1.0 MPa capacity. Driven by an AC220V terminal-type coil consuming 3.5 VA, it achieves a 0.05s response time. The 32mm bore generates 402N 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 decentralized design eliminates remote valves and excess plumbing. The manifold connects to the cylinder via an O8xO5 PU tube, and the valve's 1/4 inch port differs from the cylinder's 1/8 inch port.

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.

| 0.7 MPa | 563 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 SAIF32X175-08A Is Used
Decentralized Stations
Ideal for large machines where running individual valve tubing is costly, allowing each 32mm bore actuator to switch itself locally via a single AC220V signal.
Compact Clamping
Provides 402N of push force at 0.5 MPa in tight spaces, using the built-in 4M210 valve to eliminate external panel hardware.
Retrofits
Perfect for upgrading existing ISO 15552 interchangeable setups where adding a remote valve manifold is physically constrained.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X175-08A the Right Choice?
Choose this self-valved SAIF unit when decentralized machine stations require compact actuation without separate valve banks. If your application demands greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. The 175mm stroke on this 32mm bore is within standard limits, but always ensure proper guide support to mitigate side loads on longer strokes.
This assembly uses an AC220V terminal connection with PT threaded ports. Remember that the built-in 5/2 valve routes air but does not lock the load; if you need true position holding under pressure loss, consider the SAIL lock cylinder series. When ordering replacements, verify the 32mm bore, 175mm stroke, 1/4 inch valve port, AC220V voltage, terminal entry, and absence of a 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 SAIF32X175-08A FAQ
The 32mm bore generates 402N of push force at 0.5 MPa. The integrated 4M210-08 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
The built-in 5/2 valve allows the cylinder to control itself from one coil signal, saving panel space. Factory set to retract when energised, it can be reconfigured to extend-when-energised by repositioning the valve.
