Airtac SAIF Series Standard Cylinder with Valve SAIF40X75-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X75-08A 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 SAIF40X75-08A
The AirTAC SAIF40X75-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This built-in valve delivers a 16.0 mm2 effective area (Cv 0.89) and switches via an AC220V terminal connection coil consuming 3.5 VA. Because the valve mounts directly via a manifold block and O8 x O5 PU tubing, it eliminates remote plumbing. The assembly operates within a 0.15-0.8 MPa range, as the valve piloting dictates the practical limit over the cylinder's 1.0 MPa rating.
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. At 0.5 MPa, this 40mm bore generates 628N of push force and 528N of pull force. The unit includes a carbon steel piston rod and PT tapered ports, reaching speeds of 30-800 mm/s without requiring lubrication.

| 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 SAIF40X75-08A Is Used
Decentralized Machine Stations
Ideal for large automated lines where routing individual valve tubes back to a central manifold is costly, allowing local control via a single AC220V signal.
Compact Assembly Automation
Delivers 628N push force in a space-tight footprint, using the built-in 4M210-08 valve to minimize external plumbing on dense production machinery.
Retrofit & Upgrade Kits
Simplifies machine upgrades by replacing a standard cylinder and separate valve setup with a self-switching unit, reducing overall pneumatic complexity.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X75-08A the Right Choice?
Choose this self-valved SAIF40X75-08A when you need decentralized control across a large machine, as it saves panel space and wiring compared to running a separate cylinder and remote valve. If your application requires less force, stepping down to a 32mm bore yields 402N push at 0.5 MPa; for heavier loads, stepping up to a 50mm bore provides 982N push at 0.5 MPa. Remember that the 5/2 valve routes air and cannot hold a load without live pressure—select a SAIL lock cylinder if static position holding is required. For stroke lengths of 300mm or more, ensure external guides are used to manage side loads and prevent rod binding.
When ordering a replacement, verify the 40mm bore, 75mm stroke, 1/4" valve port (code 08), AC220V voltage, terminal electrical entry, PT thread type, and standard carbon steel rod. This unit lacks a magnet; specify the -S option if you need to mount CMSE reed or DMSE electronic sensors for position feedback.
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 SAIF40X75-08A FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa, scaling up to 1130N push at 0.9 MPa. The built-in 4M210-08 valve provides a 16.0 mm2 effective area (Cv 0.89) with a maximum frequency of 5 cycles per second.
The integrated 5/2 solenoid valve allows the cylinder to switch itself from one coil signal, saving panel space and tubing for decentralized installations. Factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised.
