The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X300-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 300mm stroke and a built-in 4M310-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.
The AirTAC SAIF80X300-08B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective area. Driven by a DC24V terminal coil consuming 3.0 W with IP65 protection and a 0.05 s response time, it eliminates the need for a remote valve. The assembly operates within a practical 0.15-0.8 MPa pressure range, as the integrated valve limits the cylinder's 1.0 MPa maximum. With a 80mm bore, it generates 2513 N of push force at 0.5 MPa.
By routing air directly through a manifold block and PU tubing (O10 x O6.5), this self-switching unit saves panel space and reduces plumbing across decentralized machine stations. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The 300mm stroke falls within the 1500mm standard limit, though external guides are recommended to manage side loads at this length. The carbon steel rod and PT tapered threads ensure robust, leak-free pneumatic connections.

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).
Ideal for large machines with distributed stations, eliminating long air lines from a central panel by integrating the 4M310 valve directly on the cylinder.
Delivers 2513 N of push force at 0.5 MPa for pressing, clamping, or joining operations where a compact footprint and reliable DC24V control are required.
Perfect for retrofitting conveyors or existing machinery where adding external valves is impractical, offering self-contained actuation via a terminal coil.
Select this 80mm bore model when your application requires substantial thrust, such as the 2513 N push force at 0.5 MPa or 4523 N at 0.9 MPa. If you need less force and faster cycling, the 63mm bore offers 1559 N push at 0.5 MPa; for heavier loads, the 100mm bore provides 3927 N at 0.5 MPa. The SAIF80X300-08B is ideal for decentralized installations where running separate valve tubing is costly or space-prohibitive. It specifies a DC24V terminal electrical entry, PT port threads, and no magnet (-S omitted). For load-holding applications, note that the 5/2 valve routes air and does not lock the piston; explore the SAIL series for pneumatic locking requirements.
Quick checklist
The 80mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, scaling to 4523 N push at 0.9 MPa. The built-in 4M310-08 5/2 valve provides a 25.0 mm2 effective area with a Cv of 1.40.
No, the 5/2 valve routes air but does not lock the load without live pressure; for position holding, consider the SAIL series. It controls itself via one DC24V coil signal, so no separate remote valve is needed. The factory default retracts the rod when energised, which can be reconfigured to extend by repositioning the valve.
