The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X225-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 225mm 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 SAIF80X225-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal coil connection, drawing just 3.0 W of power with an IP65 rating and a rapid 0.05 s activation time. The built-in valve provides a Cv of 1.40 and an effective orifice of 25.0 mm2, driving the 80mm bore to deliver 2513N of push force at 0.5 MPa. While the base cylinder rates to 1.0 MPa, the practical operating range for this assembled unit is 0.15-0.8 MPa due to the valve's internal pilot limits.
By default, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-contained design switches itself from one coil signal, eliminating the need for a separate remote valve and significantly reducing tubing and panel space for decentralized machine stations. The manifold connects to the cylinder via PU tubing (O10 x O6.5), and it is important to note the valve port (1/4") differs from the cylinder port (3/8"). The standard carbon steel rod provides durable operation across the 30-800 mm/s speed range.

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 multiple stations, eliminating long air lines from a central panel by controlling the 2513N thrust directly at the point of use.
Delivers robust 80mm bore clamping power in space-constrained fixtures where fitting a separate 4M310 valve and manifold block is physically impossible.
Simplifies machine upgrades by replacing complex pneumatic banks with a single DC24V electrical signal, drastically cutting tubing installation costs.
Choose this 80mm bore SAIF when your application demands high thrust in a compact footprint, stepping up from the 63mm bore which provides 1559N of push force at 0.5 MPa. If your system requires even higher forces up to 3927N at 0.5 MPa, you would step up to the 100mm bore variant. The self-valved SAIF architecture is ideal for space-tight machines or decentralized stations where running separate valve tubing is costly and complex. For replacements, verify the 80mm bore, 225mm stroke, 4M310-08 valve port, DC24V terminal electrical entry, PT thread, and standard carbon steel rod. Since the stroke is 225mm, ensure adequate guiding to prevent excessive side-load wear on the rod. Note that the built-in 5/2 valve routes air and is not a lock; the air cushion only decelerates near stroke end. For true position holding under load loss, consider the SAIL or BSAI clamp-lock series instead.
Quick checklist
The 80mm bore generates 2513N of push force and 2268N of pull force at 0.5 MPa. The built-in 4M310-08 valve provides an effective area of 25.0 mm2 (Cv 1.40) and operates at a maximum frequency of 4 cycles per second.
This model uses a DC24V terminal coil. By factory default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve. The integrated 5/2 valve holds its position via internal pilot pressure, meaning no separate remote valve is required to drive the cylinder.
