Airtac SAIF Series Standard Cylinder with Valve SAIF50X75S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X75S-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 75mm 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 SAIF50X75S-06B
The AirTAC SAIF50X75S-06B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. With an effective orifice of 14.0 mm2 (Cv 0.78), this self-contained unit eliminates the need for remote plumbing. It operates on a DC24V terminal connection drawing 3.0 W, protected to IP65 with a 0.05 s response time. The integrated valve limits the practical working pressure to 0.15-0.8 MPa, while the 50mm bore generates 982 N of push force at 0.5 MPa. A magnet is included for CMSE reed and DMSE electronic sensors.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. The manifold uses an O8 x O5 PU tube to bridge the valve and cylinder. Note that the valve port is PT1/8 while the cylinder port remains 1/4 inch. This decentralized design requires only a single electrical signal to drive the actuator, saving significant panel space and tubing across large machines.

|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAIF50X75S-06B Is Used
Decentralized Automation Stations
Ideal for large machines where routing individual valve lines back to a central manifold is impractical. The built-in 4M210 valve allows the SAIF50X75S-06B to operate independently from a single DC24V signal.
Space-Constrained Clamping
Perfect for compact assembly cells where panel space is tight. The integrated valve manifold and 50mm bore deliver 982 N of push force without requiring a separate valve bank nearby.
Machine Retrofitting
Retrofit older machines by replacing a standard cylinder and remote valve setup with this self-switching unit. It simplifies wiring and reduces overall pneumatic plumbing complexity.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X75S-06B the Right Choice?
Choose this self-valved SAIF50X75S-06B when your machine layout demands decentralized control and running separate valve tubing is too costly. If you need higher thrust, stepping up to the 63mm bore yields 1559 N push force at 0.5 MPa, while dropping to a 40mm bore reduces it to 628 N. The 4M210-06 valve operates at up to 5 cycles per second. Remember that the 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, select the SAIL lock or BSAI clamp-lock cylinder. When ordering replacements, match the 50mm bore, 75mm stroke, 06 valve port, DC24V voltage, terminal entry, PT threads, and the -S magnet.
Because the stroke is under 300mm, side-loading is less critical than on longer strokes, but always ensure the load is guided to prevent rod binding. The carbon steel rod provides standard durability for general pneumatics.
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 SAIF50X75S-06B FAQ
The 50mm bore generates 982 N of push force and 825 N of pull force at 0.5 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and can cycle up to 5 times per second.
No separate valve is needed; the 4M210-06 5/2 solenoid valve is mounted directly on the cylinder. By factory default, the rod retracts when the DC24V coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
