Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08E 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-08E
The AirTAC SAIF32X150S-08E is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve with a 16.0 mm2 orifice (Cv 0.89). Equipped with an AC24V terminal coil drawing 3.5 VA, it achieves a rapid 0.05 s activation time. The integrated manifold uses an O8 x O5 PU tube to bridge the valve and cylinder, eliminating the need for remote plumbing. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled unit, even though the bare cylinder rates to 1.0 MPa.
At 0.5 MPa this 32 mm bore generates 402 N of push force and 345 N of pull force. 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. The -S magnet supports CMSE reed and DMSE electronic sensors for precise end-of-stroke detection, while the carbon steel rod and PT tapered threads ensure durable, leak-free connections.

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-08E Is Used
Decentralized Stations
Perfect for large machines with distributed stations, allowing a single AC24V signal to actuate the cylinder without running long valve tubing back to a central panel.
Compact Clamping
The 32 mm bore delivers 402 N of push force at 0.5 MPa, making it suitable for light-duty clamping and positioning tasks where envelope space is tight.
Retrofit Upgrades
Ideal for upgrading existing ISO 15552 interchangeable setups where adding a separate valve manifold is costly or physically impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X150S-08E the Right Choice?
Choose this self-valved SAIF unit when your machine layout demands decentralized control, saving panel space and eliminating long tubing runs to a remote valve bank. If your application requires higher thrust, stepping up to the 40 mm bore yields 628 N push force at 0.5 MPa. For this 150 mm stroke, ensure adequate guiding to prevent excessive side loads on the rod, as the air cushion only decelerates the piston near the stroke ends and cannot hold a suspended load.
When specifying a replacement, verify the 32 mm bore, 150 mm stroke, 4M210-08 valve with 1/4" valve port, AC24V voltage, terminal electrical entry, PT thread type, and the -S magnet option. Remember that the 5/2 valve routes air but does not lock the load mechanically; for true position holding under pressure loss, consider the SAIL lock series instead.
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-08E FAQ
At 0.5 MPa, the 32 mm bore provides 402 N push and 345 N pull force. The integrated 4M210-08 5/2 valve has a 16.0 mm2 orifice with a Cv of 0.89, supporting a maximum frequency of 5 cycles per second.
Yes. By default, the factory setting retracts the rod when the AC24V coil is energised. However, you can reconfigure it to extend-when-energised by repositioning the valve on the manifold block, providing flexibility without needing a separate remote valve.
