The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X500-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 500mm 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 SAIF80X500-08A is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective orifice. Driven by an AC220V terminal entry coil consuming 3.5 VA, it eliminates the need for a separate remote valve. The integrated manifold connects to the cylinder via PU tubing (O10 x O6.5), and the assembly operates at 0.15-0.8 MPa, governed by the valve's pressure limit rather than the cylinder's 1.0 MPa rating.
Delivering 3518N of push force at 0.7 MPa, this ISO 15552 dimensionally interchangeable unit is designed for decentralized installations across large machines. By default, the piston rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by simply repositioning the valve on the manifold block.

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-scale machinery with decentralized stations, switching directly from a single AC220V coil signal without running long valve tubing back to a central panel.
Provides 3518N of push force at 0.7 MPa for pressing and joining operations, with the 4M310-08 valve offering a 1.40 Cv flow to maintain speed across the 500mm stroke.
Perfect for machine upgrades where adding a remote valve bank is too costly, using the existing ISO 15552 mounting interface and integrated manifold block.
Choose this 80mm bore when a 63mm bore (providing 1559N push at 0.5 MPa) is insufficient, or step down if the 100mm bore (5497N push at 0.7 MPa) exceeds your space constraints. The self-valved SAIF80X500-08A beats a separate cylinder and remote valve setup by drastically reducing panel space, wiring, and plumbing complexity. When ordering a replacement, verify the 500mm stroke, 4M310-08 valve port, AC220V terminal coil, PT thread, and absence of a magnet (-S). Because the stroke is 500mm, ensure adequate guide support to prevent excessive side loads on the rod. Note that the built-in 5/2 valve routes air and is not a lock; for load-holding, consider the SAIL series.
Quick checklist
The 80mm bore generates 3518N of push force at 0.7 MPa and 2268N of pull force. The built-in 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) with a max frequency of 4 cycles/sec.
No, the 5/2 valve routes air but does not lock the load; for position holding, use the SAIL series. 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.
