Airtac SAIF Series Standard Cylinder with Valve SAIF40X500-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X500-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 500mm 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 SAIF40X500-06B
The AirTAC SAIF40X500-06B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. Driven by a DC24V terminal entry coil drawing 3.0 W, it delivers a push force of 628 N at 0.5 MPa. The integrated valve provides an effective area of 14.0 mm2 (Cv 0.78) and switches up to 5 cycles per second. Because the valve is mounted directly via a manifold block using O8 x O5 PU tubing, it eliminates remote plumbing and saves panel space, making it highly effective for decentralized machine stations.
While the cylinder body itself rates to 1.0 MPa, the practical operating pressure for this valved assembly is 0.15-0.8 MPa, with a speed range of 30-800 mm/s. By default, the factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence requires it. The unit features a carbon steel piston rod, PT1/8 cylinder ports, and adjustable air cushions at both ends to decelerate the 500 mm travel smoothly.

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 SAIF40X500-06B Is Used
Decentralized Conveyor Diverters
Ideal for routing packages on long conveyor lines where running individual air lines back to a central valve bank is impractical and costly.
Compact Assembly Stations
Provides self-contained actuation in tight multi-station machine layouts, minimizing pneumatic plumbing and maximizing floor space.
Automated Component Pushing
Delivers 628 N of push force at 0.5 MPa for positioning parts, with a built-in DC24V valve ensuring rapid 0.05 s response times.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X500-06B the Right Choice?
Choose this 40 mm bore when you need 628 N of push force at 0.5 MPa and want to avoid the tubing runs of a separate remote valve. If your application requires less force, the 32 mm bore offers 402 N; if you need more clamping power, stepping up to the 50 mm bore provides 982 N. This self-switching design is ideal for space-tight machines where wiring a single DC24V terminal coil is far simpler than routing air lines back to a central manifold.
For motion control, remember the built-in 5/2 valve routes air but does not lock the load mechanically; if you need true position holding without live pressure, consider the SAIL lock variant. Because this stroke is 500 mm, ensure adequate guiding to prevent side-loading damage to the profile barrel. To replace this unit exactly, match the 40 mm bore, 500 mm stroke, 4M210-06 valve (1/8" port), DC24V voltage, terminal entry, PT threads, and standard carbon steel rod without a 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 SAIF40X500-06B FAQ
At 0.5 MPa, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. The integrated 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and supports a maximum frequency of 5 cycles per second.
No, the SAIF40X500-06B has a 4M210 5/2 valve built directly onto the cylinder via a manifold block. It operates from a single DC24V terminal coil signal. By factory default, energising the coil retracts the rod, but the valve can be repositioned to extend-when-energised.
