Airtac SAIF Series Standard Cylinder with Valve SAIF40X160S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X160S-08B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 160mm 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 SAIF40X160S-08B
The AirTAC SAIF40X160S-08B is a double-acting ISO 15552 profile cylinder that integrates a 4M210-08 5/2 solenoid valve directly onto its body, yielding a Cv of 0.89. Driven by a DC24V terminal coil drawing 3.0 W, it eliminates the need for remote plumbing. The assembly operates within a 0.15-0.8 MPa range, as the built-in valve limits the 1.0 MPa cylinder capacity, delivering 628N of push force at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, though this can be reconfigured to extend-when-energised by repositioning the valve. The manifold connects to the cylinder via an O8xO5 PU tube, and the unit includes a magnet for position sensing with CMSE reed or DMSE electronic switches. This self-contained design requires only a single electrical signal to operate, making it highly suited for decentralized stations where panel space is tight.

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)

|---|---|---|
| 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 SAIF40X160S-08B Is Used
Decentralized Stations
Ideal for large machines with multiple stations, eliminating long tubing runs by switching locally from a single DC24V signal.
Compact Assembly Machines
Fits into tight machine footprints where a separate valve manifold would occupy too much panel or framework space.
Retrofit Automation
Perfect for upgrading existing lines where routing new pneumatic tubing back to a central control cabinet is costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X160S-08B the Right Choice?
Choose this 40mm bore when an application requires around 628N push force at 0.5 MPa; stepping down to a 32mm bore drops the push force to 402N, while a 50mm bore increases it to 982N. A self-valved SAIF unit is ideal over a separate cylinder and remote valve when you need to minimize tubing and wiring across decentralized machine layouts.
For replacements, match the 40mm bore, 160mm stroke, 1/4" valve port, DC24V voltage, terminal entry, PT thread, and the -S magnet. Since the stroke is 160mm, ensure adequate guiding to prevent excessive side loads on the rod. Note that while the 5/2 valve routes air, it does not hold the load without live pressure; for true load-holding, 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 SAIF40X160S-08B FAQ
The 40mm bore generates 628N of push force at 0.5 MPa. The built-in 4M210-08 valve provides an effective flow area of 16.0 mm2 (Cv 0.89) and can cycle up to 5 times per second.
It uses a 5/2 solenoid valve that holds position via internal pilot pressure. The factory setting retracts the rod when the DC24V coil is energised, but it can be reconfigured to extend-when-energised. This eliminates the need for a separate remote valve.
