Airtac SAIF Series Standard Cylinder with Valve SAIF40X50-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X50-06B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 50mm 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 SAIF40X50-06B
The AirTAC SAIF40X50-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry consuming 3.0 W, a PT1/8 cylinder port, and a 1/8 inch valve port. The built-in valve provides an effective area of 14.0 mm2 (Cv 0.78) and supports a maximum frequency of 5 cycles per second. Because the valve manifold mounts directly to the cylinder body using an O8 x O5 PU tube, it eliminates the need for remote plumbing and saves panel space.
While the cylinder body itself is rated for 1.0 MPa, the practical operating pressure for this valved assembly is 0.15-0.8 MPa, operating at speeds of 30-800 mm/s. The 40 mm bore generates 628 N of push force and 528 N of pull force at 0.5 MPa. From the factory, the default setting retracts the piston rod when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. The assembly uses a carbon steel piston rod and standard variable air cushions at both ends.

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 SAIF40X50-06B Is Used
Decentralized Stations
Perfect for large machines with multiple actuation points, as the built-in 4M210 valve allows local control via a single DC24V signal without a massive central manifold.
Compact Clamping
Provides 628 N of clamping push force at 0.5 MPa in tight spaces where external valves and tubing would interfere with the machinery envelope.
Retrofit Upgrades
Ideal for upgrading existing ISO 15552 dimensional installations where running new pneumatic tubing to a remote valve is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X50-06B the Right Choice?
Choose this 40 mm bore SAIF model when you need 628 N push force at 0.5 MPa and want to eliminate separate valve plumbing. If your application requires less force, stepping down to a 32 mm bore yields 402 N push force; if you need more power, a 50 mm bore provides 982 N. This self-valved cylinder is ideal for decentralized stations across large machines, as a single DC24V coil signal drives the motion without routing long tubing runs to a central manifold. The 4M210-06 valve operates at 5/2 positions held by internal pilot pressure, not a spring. It does not hold the load without live air pressure, so for locking requirements consider the SAIL series.
When ordering a replacement, verify the 50 mm stroke, 1/8 inch valve port, DC24V voltage, terminal electrical entry, and PT thread type. This base model does not include a magnet for sensors; adding an -S suffix enables compatibility with AirTAC CMSE reed and DMSE electronic solid-state switches.
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 SAIF40X50-06B FAQ
At 0.5 MPa, the 40 mm bore generates 628 N of push force and 528 N of pull force. The integrated 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and supports up to 5 cycles per second.
No, the SAIF40X50-06B switches itself using the built-in valve, requiring only a DC24V electrical signal. By default, the rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
