Airtac SAIF Series Standard Cylinder with Valve SAIF40X80-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X80-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 80mm 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 SAIF40X80-06A
The AirTAC SAIF40X80-06A is a double-acting ISO 15552 profile cylinder with a built-in 4M210-06 5/2 solenoid valve, delivering a 16.0 mm2 flow (Cv 0.89). Driven by an AC220V terminal entry coil drawing 3.5 VA, it eliminates the need for a remote valve island. The manifold connects to the cylinder via an O8 x O5 PU tube, while the valve itself features a PT 1/8 port. Because the 4M210 valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled unit, even though the bare cylinder rates to 1.0 MPa.
At 0.5 MPa it generates 628 N of push force and 528 N of pull force. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. This self-switching design drastically cuts plumbing and panel space, making it perfect for decentralized stations across large machines. It uses a carbon steel rod and adjustable air cushions at both ends to decelerate the load near stroke extremes.

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 SAIF40X80-06A Is Used
Decentralized Stations
Ideal for large machines with decentralized stations, switching itself from one AC220V coil signal without needing a remote valve bank.
Space-Tight Machines
Fits compact assemblies where panel space is limited, using the built-in 4M210 valve and short PU tubing to minimize plumbing.
Retrofit Installations
Perfect for retrofits where running new valve tubing is costly, offering a self-contained 628 N push force actuator.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X80-06A the Right Choice?
Choose this 40 mm bore when a 32 mm cylinder (402 N push at 0.5 MPa) is too weak, but a 50 mm bore (982 N push) is physically oversized. The SAIF40X80-06A is ideal for space-tight machines where running separate valve tubing is costly. The integrated 5/2 valve routes air internally via pilot pressure, holding its last position without live pressure drops, but note it is not a lock—use SAIL for load-holding. This specific SKU uses an AC220V terminal coil with PT threads and no sensor magnet. When replacing, match the 40 mm bore, 80 mm stroke, 06 valve port, AC220V voltage, terminal entry, and PT thread exactly.
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 SAIF40X80-06A FAQ
At 0.5 MPa, the 40 mm bore provides 628 N push and 528 N pull force. The integrated 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and a max frequency of 5 cycles per second.
No, it has a built-in 4M210 valve. The factory setting retracts the rod when the AC220V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
