Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08F
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08F 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-08F
The AirTAC SAIF32X300S-08F 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 an effective area of 16.0 mm2. Driven by a DC12V terminal entry coil drawing 3.0 W, it achieves IP65 protection and responds in 0.05 s or less. Although the cylinder body rates to 1.0 MPa, the integrated valve limits the practical working pressure to 0.15-0.8 MPa. The 32 mm bore generates 402 N of push force at 0.5 MPa, making it suited for lighter duty cycles.
This assembly uses a PT1/8 cylinder port and an O8 x O5 PU tube to bridge the manifold block, meaning the valve port differs from the cylinder port. By default, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. Fitted with a magnet, it supports CMSE reed and DMSE electronic sensors for precise position feedback across the 300 mm stroke.

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-08F Is Used
Decentralized Assembly Stations
Eliminates the need for remote valve islands on large machines by switching the 32 mm bore locally from a single DC12V signal.
Compact Positioning Actuators
Fits into tight machine envelopes where plumbing a separate 5/2 valve and tubing would consume excessive panel space.
Retrofit Pneumatic Modules
Ideal for upgrading existing lines where running new air lines is costly, using the built-in manifold and O8 x O5 PU tubing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X300S-08F the Right Choice?
Choose this self-contained SAIF unit when decentralized installation eliminates the cost of running separate valve tubing across a large machine. The 32 mm bore yields 402 N push at 0.5 MPa; if your application requires greater force, stepping up to the 40 mm bore provides 628 N at the same pressure. Conversely, if you need higher flow, note that this 4M210-08 valve provides 16.0 mm2 effective area, whereas the 4M210-06 variant offers 14.0 mm2. Because the 5/2 valve only routes air and the air cushion merely decelerates near stroke end, neither acts as a lock; for load-holding requirements, consider the SAIL lock or BSAI clamp-lock series instead. At 300 mm stroke, ensure adequate guiding to prevent excessive side loads on the rod. To replace this unit, match the 32 mm bore, 300 mm stroke, 1/4 inch valve port, DC12V 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-08F FAQ
The 32 mm bore generates 402 N of push force at 0.5 MPa and 724 N at 0.9 MPa. The integrated 4M210-08 5/2 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
No, the 5/2 valve routes air and holds its position via internal pilot, but it is not a mechanical lock; the air cushion only decelerates near stroke end. This DC12V terminal entry coil draws 3.0 W. By factory default, energising the coil retracts the rod, but you can reposition the valve to extend-when-energised.
