Airtac SAIF Series Standard Cylinder with Valve SAIF40X150-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X150-08B is a genuine double-acting ISO 15552 cylinder with a Ø40mm 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 SAIF40X150-08B
The AirTAC SAIF40X150-08B is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve. It features a carbon steel rod and a PT1/4 tapered cylinder port. The integrated valve offers a 16.0 mm2 effective area (Cv 0.89) and connects to the cylinder via an O8 x O5 PU tube. Driven by a DC24V terminal coil consuming 3.0 W, it activates in 0.05 s with IP65 protection.
While the bare cylinder rates to 1.0 MPa, the internal pilot valve limits the practical operating range to 0.15-0.8 MPa. It delivers 628N of push force at 0.5 MPa. Factory-set to retract when energized, the valve can be repositioned to extend on signal. This decentralized design eliminates remote plumbing, saving 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAIF40X150-08B Is Used
Decentralized Assembly Lines
Eliminates remote valve banks by switching directly from the DC24V terminal coil, saving panel space across large machines.
Compact Handling Units
Delivers 628N push force at 0.5 MPa in tight spaces where running separate valve tubing is costly or impractical.
Machine Retrofitting
Simplifies upgrades by bundling the cylinder and 5/2 valve, reducing pneumatic plumbing and electrical wiring overhead.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X150-08B the Right Choice?
Choose this 40mm bore when you need 628N push force at 0.5 MPa; stepping down to a 32mm bore yields 402N, while a 50mm bore provides 982N. The self-valved SAIF40X150-08B beats a separate cylinder plus remote valve by cutting tubing and wiring, ideal for decentralized stations. It uses a 1/4" valve port and DC24V terminal connection. Remember, the 5/2 valve routes air but does not hold the load without live pressure; use SAIL for locking. For this 150mm stroke, ensure proper guide support to prevent side-load wear.
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 SAIF40X150-08B FAQ
At 0.5 MPa, it provides 628N push and 528N pull force. The built-in 4M210-08 valve has a 16.0 mm2 orifice with a Cv of 0.89.
The DC24V 5/2 valve switches the cylinder directly from one signal. Factory-set to retract when energized, it can be repositioned to extend. It routes air but is not a lock; it cannot hold the load without live pressure.
