Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 150mm 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 SAIF32X150S-08B
The AirTAC SAIF32X150S-08B 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 on a DC24V terminal coil drawing 3.0 W. Because the cylinder itself is rated up to 1.0 MPa but the built-in valve operates from 0.15-0.8 MPa, the practical working range for this complete unit is 0.15-0.8 MPa. The 32mm bore generates 402N of push force at 0.5 MPa.
By default, the factory setting retracts the piston rod when the coil is energised, but it can be reconfigured to extend-when-energised simply by repositioning the valve. The manifold block connects to the cylinder using PU tubing (O8 x O5), meaning the 1/4" valve port differs from the cylinder's 1/8" port. Fitted with a magnet, it supports CMSE reed and DMSE electronic sensors for position feedback, while the carbon steel rod handles standard loads.

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 SAIF32X150S-08B Is Used
Decentralized Stations
Eliminates the need for a remote valve bank, allowing independent cylinder control across large-scale machinery using a single DC24V signal.
Compact Assembly Lines
Saves valuable panel and tubing space by mounting the 5/2 valve directly to the ISO 15552 profile barrel, perfect for tight automation cells.
Retrofit & Upgrades
Ideal for upgrading older pneumatic setups where running new air lines back to a central manifold is too costly or complex.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08B the Right Choice?
Choose this self-valved SAIF unit when you need to eliminate remote valve plumbing and save panel space in decentralized machine stations. If your application requires greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. For heavier loads or larger tubing, the 63mm bore offers 1559N. This DC24V terminal configuration is ideal for low-voltage control systems, and the PT thread ensures a reliable tapered seal.
Since the stroke is 150mm, ensure proper guide support to prevent excessive side-loading on the rod. Remember that the built-in 5/2 valve routes air but does not lock the load; for position-holding requirements, consider the SAIL lock cylinder or BSAI clamp-lock series. When ordering a replacement, confirm the 32mm bore, 150mm stroke, 1/4" valve port, DC24V voltage, terminal entry, PT thread, and the -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 SAIF32X150S-08B FAQ
The 32mm bore generates 402N of push force and 345N of pull force at 0.5 MPa. While the cylinder body rates to 1.0 MPa, the practical operating range for the assembled SAIF unit is 0.15-0.8 MPa due to the built-in 4M210 valve limits.
Yes. The factory default setting retracts the rod when the DC24V coil is energised, but you can reconfigure it to extend-when-energised by repositioning the 5/2 valve on the manifold block. This self-switching design means no separate remote valve is required.
