Airtac SAIF Series Standard Cylinder with Valve SAIF32X300-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X300-08A is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 300mm 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 SAIF32X300-08A
The AirTAC SAIF32X300-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Equipped with a Cv 0.89 flow capacity and an AC220V terminal coil drawing 3.5 VA, it delivers a push force of 402N at 0.5 MPa. Because the cylinder body rates to 1.0 MPa but the built-in valve operates from 0.15 to 0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa.
This self-contained design switches itself from a single coil signal, eliminating the need for a remote valve and drastically reducing panel space and plumbing. The manifold connects to the cylinder via an O8xO5 PU tube, while the valve port is 1/4 and the cylinder port is 1/8. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your sequence requires it.

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 (Ø32mm)

| 0.5 MPa | 402 N | 346 N |
| 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 SAIF32X300-08A Is Used
Decentralized Assembly Stations
Eliminates the need for long air lines back to a central manifold, driving local clamping directly from the integrated 4M210 valve.
Space-Tight Diverters
Fits compact machinery profiles where mounting a separate valve island is physically impossible, using a single AC220V signal to actuate gates.
Machine Retrofitting
Ideal for upgrading older lines where adding new valve plumbing is prohibitively expensive, leveraging the built-in 5/2 valve for direct control.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X300-08A the Right Choice?
Choose this 32mm bore when your application demands a 402N push force at 0.5 MPa; stepping down is not an option in the SAIF range, but stepping up to the 40mm bore yields 628N if higher thrust is needed. A self-valved SAIF excels over a separate cylinder and remote valve in decentralized stations where running tubing across a large machine is costly. To replace this unit, match the 32mm bore, 300mm stroke, 1/4 valve port, AC220V voltage, terminal entry, PT thread, and no magnet. Because the stroke is 300mm, ensure adequate guiding to prevent excessive side-load wear on the rod seals.
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 SAIF32X300-08A FAQ
At an operating pressure of 0.5 MPa, this 32mm bore cylinder provides a push force of 402N and a pull force of 345N. The maximum push force is 724N at 0.9 MPa.
The integrated 4M210-08 is a 5/2 valve that holds its last position via internal pilot pressure, not a spring. By default, it retracts the rod when the AC220V coil is energised, but it can be reconfigured to extend-when-energised. It does not hold the load without live air pressure.
