Airtac SAIF Series Standard Cylinder with Valve SAIF40X75S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X75S-08B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 75mm stroke and a built-in 4M210-08 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 SAIF40X75S-08B
The AirTAC SAIF40X75S-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve, offering a Cv of 0.89 and a 16.0 mm2 effective area. Driven by a DC24V terminal entry coil consuming 3.0 W, it integrates the manifold and PU tubing (O8xO5) directly onboard. The cylinder port is PT1/4, while the valve port is 1/4 inch. Equipped with a magnet, it supports CMSE reed and DMSE electronic sensors for precise position detection.
Because the cylinder body rates to 1.0 MPa but the integrated 4M valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. By switching itself from one coil signal, it eliminates remote plumbing and saves panel space, making it ideal for decentralized stations across large machines.

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 SAIF40X75S-08B Is Used
Decentralized Machine Stations
Eliminates the need for a remote valve island on large assembly lines, driving the 40mm bore directly from a single DC24V signal.
Space-Tight Robotics
The integrated manifold and short PU tubing save critical envelope space where running external plumbing is physically impossible.
Retrofit Automation
Ideal for upgrading older machines where routing new valve tubing back to a central panel is too costly or complex.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X75S-08B the Right Choice?
Choose this 40mm bore if you need 628N push force (528N pull) at 0.5 MPa; stepping down to a 32mm bore drops the push force to 402N, while a 50mm bore raises it to 982N. A self-valved SAIF beats a separate cylinder and remote valve when you want to minimize wiring and tubing in space-tight machines. This DC24V terminal entry configuration with PT threads offers a 0.05s response time and IP65 protection. For exact replacements, match the 40mm bore, 75mm stroke, 4M210-08 valve port, DC24V voltage, terminal entry, PT thread, and -S magnet.
Note that the built-in 5/2 valve routes air but does not lock the load mechanically; if you need true load-holding without live pressure, consider the SAIL lock variant. The standard carbon steel rod handles standard side loads, and the variable air cushions at both ends safely decelerate the piston near stroke ends within the 30-800 mm/s speed range.
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 SAIF40X75S-08B FAQ
At 0.5 MPa, this 40mm bore cylinder provides 628N push and 528N pull force. The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
No, the 4M210 5/2 valve is built directly onto the cylinder. By default, the rod retracts when the DC24V coil is energised, but the valve can be repositioned to extend-when-energised. It operates on 0.15-0.8 MPa and requires no external pilot lines.
