Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08B 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-08B
The AirTAC SAIF32X300S-08B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This valve provides a 16.0 mm2 effective area (Cv 0.89) and operates at up to 5 cycles per second. The assembly is driven by a DC24V terminal entry coil consuming 3.0 W, protected to IP65 with a 0.05 s response time. Because the cylinder rates to 1.0 MPa but the integrated valve operates at 0.15-0.8 MPa, the practical working pressure for this SAIF unit is 0.15-0.8 MPa. The 32 mm bore generates 402 N of push force at 0.5 MPa.
This model includes a magnet for CMSE reed and DMSE electronic sensors. The manifold connects the valve to the cylinder using an O8 x O5 PU tube, and the valve port (1/4") is intentionally larger than the 1/8" cylinder port to maximize flow. By default, the factory valve configuration retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. This decentralized design eliminates remote plumbing and saves panel space.

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 SAIF32X300S-08B Is Used
Decentralized Machine Stations
Ideal for large assembly lines where routing individual valve lines back to a central manifold is inefficient. The integrated 4M210 valve lets this 32mm cylinder switch itself locally.
Compact Clamping Fixtures
Delivers 402N of push force at 0.5MPa in a tight envelope. The built-in valve and DC24V terminal coil minimize the pneumatic and electrical footprint on dense tooling plates.
Component Ejection Systems
The 300mm stroke provides extended reach for part ejection. Operating at up to 5 cycles/sec, the unit handles rapid, repetitive motions without needing a separate remote valve.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08B the Right Choice?
Choose this self-valved SAIF unit when your machine layout makes running separate valve tubing costly or impractical. The 32 mm bore yields 402 N push at 0.5 MPa; if your application requires more force, stepping up to the 40 mm bore provides 628 N push at the same pressure. This specific SKU is built for DC24V power with a standard terminal electrical entry and PT tapered threads. The 300 mm stroke is well within the 1000 mm maximum standard stroke for this bore.
For any stroke of 300 mm or longer, you must account for mechanical side loads. Ensure appropriate guiding to prevent rod bending and premature seal wear. Note that the built-in 5/2 valve routes air but does not lock the load; if your process requires true mechanical position holding without live pressure, consider the AirTAC SAIL lock or BSAI clamp-lock cylinder series instead. To replace this unit, match the 32 mm bore, 300 mm stroke, 1/4" valve port, DC24V voltage, terminal entry, PT threads, and the -S magnet option.
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-08B FAQ
The 32mm bore generates 402N of push force and 345N of pull force at 0.5MPa. The built-in 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89), providing ample flow for the cylinder's 30-800 mm/s speed range.
No, the SAIF32X300S-08B switches itself from a single DC24V coil signal. By default, the factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised. This eliminates separate valves, reduces tubing, and saves panel space.
