Airtac SAIF Series Standard Cylinder with Valve SAIF40X160S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X160S-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 160mm stroke and a built-in 4M210-06 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-06B
The AirTAC SAIF40X160S-06A is a double-acting ISO 15552 profile cylinder with an integrated 4M210-06 5/2 solenoid valve, yielding a 14.0 mm2 effective area (Cv 0.78). Driven by a DC24V terminal coil drawing 3.0 W, it activates in 0.05 s or less with IP65 protection. The assembly includes a magnet for CMSE and DMSE sensors and uses a PT1/8 tapered cylinder port. Because the built-in valve operates at 0.15-0.8 MPa, the practical working range for the valved unit is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa. At 0.5 MPa it generates 628N of push force and 528N of pull force.
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. The manifold links the valve to the cylinder barrel using an O8 x O5 PU tube, meaning the valve port (1/8) differs from the cylinder port (1/4). This decentralized design eliminates remote valves and excess panel plumbing, requiring only a single coil signal to drive the motion.

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-06B Is Used
Decentralized Assembly Lines
Eliminates the need for a central valve manifold on large machines by switching locally via the integrated 4M210 valve, saving panel space and tubing.
Compact Clamping Fixtures
Provides 628N of push force at 0.5 MPa in a tight ISO 15552 profile envelope, ideal for securing workpieces during machining operations.
Retrofit Automation Projects
Simplifies machine upgrades where routing new air lines to a remote valve is difficult, requiring only a 24V electrical signal to operate.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X160S-06B the Right Choice?
Choose this 40mm bore if you need more force than the 32mm version (which provides 402N push at 0.5 MPa) but want a smaller envelope than the 50mm bore (982N push). The SAIF40X160S-06A is ideal for decentralized stations where running separate valve tubing is costly, as it switches itself from one coil signal. Select this specific DC24V terminal configuration when matching existing 24V control panels, and note the PT1/8 valve port suits compact pneumatic layouts. For replacements, verify the 160mm stroke, 06 valve port, DC24V voltage, terminal entry, PT thread, and -S magnet requirement. Because the 160mm stroke is over 300mm, ensure adequate guide support to prevent rod side-loading and premature seal wear. Remember that the 5/2 valve routes air but does not lock the load; for position holding, consider a SAIL lock cylinder 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-06B FAQ
At 0.5 MPa, this 40mm bore cylinder generates 628N of push force and 528N of pull force. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and operates at a maximum frequency of 5 cycles per second.
It uses a 5/2 solenoid valve that holds position by pilot pressure, not a spring. The factory default retracts the rod when the DC24V terminal coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve. This self-contained design means no separate remote valve is needed.
