A 30209 bearing is a type of rolling element bearing commonly used in various industrial applications. These bearings are designed to support radial loads and are characterized by their cylindrical inner and outer rings, as well as their rolling elements, which are typically spherical or cylindrical in shape.

The "30209" designation refers to the bearing's dimensions, with the first two digits indicating the bore diameter (30 mm) and the last three digits indicating the outside diameter (90 mm). This size is one of the more common bearing sizes used in machinery, equipment, and vehicles.

30209 bearings are renowned for their durability, reliability, and ability to withstand high radial loads. They are commonly found in a variety of industrial equipment, such as electric motors, gearboxes, pumps, and compressors. Additionally, they are used in various transportation applications, including automobile wheel hubs, transmission systems, and axle assemblies.

One of the key advantages of 30209 bearings is their ability to maintain consistent performance and minimize the risk of premature failure. This is achieved through the use of high-quality materials, precise manufacturing techniques, and rigorous quality control measures. The bearings are designed to operate smoothly and efficiently, reducing the likelihood of mechanical issues and prolonging the lifespan of the equipment they are used in.

Here are the typical dimensions for a 30209 bearing:

Bore Diameter: 45 mm
Outside Diameter: 85 mm
Width: 19 mm

The key dimensions are:

Bore Diameter (d): 45 mm
This is the diameter of the inner ring or hub that the bearing fits onto.

Outside Diameter (D): 85 mm
This is the diameter of the outer ring or housing that the bearing sits in.

Width (B): 19 mm
This is the overall width or thickness of the bearing.

Other common specifications for a 30209 bearing include:

Dynamic Load Rating (C): Typically around 48 kN
Static Load Rating (C0): Typically around 43 kN
Rotational Speed (n): Up to 5,300 rpm

These load ratings and speed capabilities make the 30209 bearing suitable for a wide range of medium-duty industrial applications that require reliable radial load support.
