Airtac SAIF Series Standard Cylinder with Valve SAIF40X225-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X225-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 225mm 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 SAIF40X225-06B
The AirTAC SAIF40X225-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This built-in valve provides a Cv of 0.78 (14.0 mm2 orifice) and mounts directly via a manifold block using O8 x O5 PU tubing, eliminating the need for remote plumbing. Equipped with a DC24V terminal entry coil, it consumes 3.0 W, features IP65 protection, and activates in 0.05 s or less. The cylinder bore is 40 mm, generating 628 N of push force at 0.5 MPa, while the carbon steel rod and PT1/8 cylinder ports ensure robust pneumatic connections.
Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates specifically within 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa. By default, the factory setting retracts the piston rod when the coil is energised; however, you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design requires only one coil signal to drive the motion, making it highly effective for decentralized installation across large machines where panel space and tubing runs are limited.

| 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 SAIF40X225-06B Is Used
Decentralized Assembly Stations
Ideal for large automated machinery where running individual valve lines back to a central panel is costly, this self-valved cylinder operates independently from a single DC24V signal.
Space-Constrained Clamping
The integrated 4M210-06 valve manifold saves valuable panel and tubing space, delivering 528 N of pull force at 0.5 MPa for compact clamping fixtures.
Retrofit Automation
Perfect for upgrading existing lines where adding external pneumatic plumbing is difficult, this unit provides a complete actuation package with a 1/8" valve port and PT1/8 cylinder connection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X225-06B the Right Choice?
Choose this 40 mm bore when an application requires around 628 N of push force at 0.5 MPa; if you need less force, step down to the 32 mm bore (402 N push at 0.5 MPa), or move up to the 50 mm bore (982 N push at 0.5 MPa) for higher loads. The integrated 4M210-06 valve with a 1/8" port offers a 5 cycle/sec max frequency, making it ideal for space-tight machines where running separate valve tubing is costly or impractical. With a 225 mm stroke, ensure you provide adequate guidance to prevent excessive side-loading on the carbon steel rod.
This SAIF unit switches itself from one DC24V terminal signal, entirely removing the need for a separate remote valve. Remember that the 5/2 valve routes air but does not lock the load mechanically; if your application requires true position holding without live pressure, consider the AirTAC SAIL lock or BSAI clamp-lock series instead. When replacing, match the 40 mm bore, 225 mm stroke, 06 (1/8") valve port, DC24V voltage, terminal entry, PT thread, and standard non-magnet configuration.
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 SAIF40X225-06B FAQ
At an operating pressure of 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. The practical working pressure for the assembled unit is 0.15-0.8 MPa, limited by the built-in 4M210-06 valve.
Yes. By default, the factory setting retracts the rod when the DC24V coil is energised. You can reconfigure it to extend-when-energised by repositioning the 5/2 valve on the manifold block, eliminating the need for a separate remote valve.
