The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X80-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 80mm 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.
The AirTAC SAIF40X80-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific configuration uses an AC220V terminal coil and delivers a 16.0 mm2 effective area (Cv 0.89). Because the valve manifold mounts directly using an O8 x O5 PU tube, it eliminates remote plumbing. The cylinder itself rates to 1.0 MPa, but the practical SAIF operating range is 0.15-0.8 MPa due to the valve's pilot pressure limits.
In this 40mm bore build, the rod retracts when the coil is energised at the factory setting, but you can reposition the valve to extend-when-energised. It delivers 628N of push force at 0.5 MPa. The unit switches itself from one coil signal, making it ideal for decentralized stations across large machines where panel space is tight.

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.

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).
Perfect for large machines with decentralized stations, eliminating long valve tubing runs by switching directly from the AC220V coil signal.
Fits into compact machinery where panel space is scarce, integrating the 4M210-08 valve and cylinder into one self-switching assembly.
Ideal for retrofits where running new valve tubing is costly, providing a standalone 628N actuator driven by a single terminal connection.
Choose this 40mm bore when you need 628N push force at 0.5 MPa. If your application requires less force, the 32mm bore offers 402N; stepping up to the 50mm bore provides 982N. A self-valved SAIF beats a separate cylinder plus remote valve in space-constrained machines by cutting tubing and wiring. This model has a PT1/4 cylinder port and a 1/4 inch valve port. It uses a standard carbon steel rod and no magnet. For load-holding, note the 5/2 valve routes air but is not a lock; consider SAIL for locking needs.
Quick checklist
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice (Cv 0.89) and a maximum frequency of 5 cycles per second.
It uses a 5/2 solenoid valve that holds position via internal pilot, not a spring. This AC220V terminal entry model retracts the rod when energised at the factory, but can be reconfigured to extend-when-energised. No separate remote valve is needed.
