Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08E 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 SAIF32X300S-08E
The AirTAC SAIF32X300S-08E is a double-acting ISO 15552 profile cylinder paired with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89 and a 16.0 mm2 effective orifice. Driven by an AC24V terminal entry coil consuming 3.5 VA, it activates in 0.05 s with an IP65 rating. The cylinder features a PT1/4 port, a 12 mm carbon steel rod, and includes a magnet for CMSE reed and DMSE electronic sensors.
Because the valve manifold routes air via an O8 x O5 PU tube, the 1/4" valve port differs from the cylinder port. While the cylinder body rates to 1.0 MPa, the internal pilot valve operates at 0.15-0.8 MPa, setting the practical working range for the assembly. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. This self-valved design eliminates remote plumbing, saving panel space for decentralized machine stations.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF32X300S-08E Is Used
Decentralized Stations
Ideal for large machines with decentralized stations, dropping the need for long valve tubing runs back to a central panel.
Space-Tight Handling
Fits compact assembly machinery where fitting a separate cylinder and valve is physically impossible.
Retrofit Automation
Perfect for upgrading existing lines where running new air lines is costly, using the AC24V terminal coil for direct control.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08E the Right Choice?
Choose this 32 mm bore when you need 402 N of push force at 0.5 MPa; step up to the 40 mm bore if your application requires 628 N. The 300 mm stroke on this profile cylinder requires attention to side loads, so use a guide rod to prevent binding. The integrated 4M210 valve hits a max frequency of 5 cycles/sec, matching well with the 30-800 mm/s speed range.
A self-valved SAIF beats a separate cylinder and remote valve when wiring and tubing costs are high, as one AC24V terminal coil signal drives the whole unit. Remember that the 5/2 valve routes air but does not lock the load without live pressure; for position holding, select a SAIL lock cylinder. To replace this unit, match the 32 mm bore, 300 mm stroke, 1/4" valve port, AC24V voltage, terminal entry, PT thread, 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 SAIF32X300S-08E FAQ
The 32 mm bore generates 402 N push and 345 N pull force at 0.5 MPa. The built-in 4M210-08 valve provides a 16.0 mm2 orifice with a Cv of 0.89.
The 5/2 valve holds its position via internal pilot pressure, not a spring. By default, it retracts the rod when the AC24V coil is energised, but you can reconfigure it to extend. It does not lock the load without live pressure; use a SAIL cylinder for holding.
