Flanged ball bearings are a particular type of ball bearing that has a flange on the outer ring. This flange is designed to aid in the bearing’s location and to prevent it from moving axially along the shaft. Flanged ball bearings are used in a variety of applications, ranging from electric motors to medical devices. A crucial aspect of selecting the appropriate flanged ball bearing for a specific application is understanding its size and how it is measured.
Determining the Size of a Flanged Ball Bearing
The size of a flanged ball bearing is typically described by a series of numbers and letters that denote specific dimensions and characteristics of the bearing. These include the bearing’s inner diameter, outer diameter, width, and the flange size. Here’s how to interpret these dimensions:
- Inner Diameter (d): The inner diameter, denoted by the symbol ‘d,’ refers to the diameter of the hole in the inner ring of the bearing. It is the diameter of the shaft that the bearing will be mounted on.
- Outer Diameter (D): The outer diameter, denoted by the symbol ‘D,’ refers to the diameter of the outer ring of the bearing, excluding the flange.
- Width (B): The width, denoted by the symbol ‘B,’ refers to the thickness of the bearing, measured from one side of the bearing to the other.
- Flange Size: The flange size refers to the dimensions of the flange on the outer ring of the bearing. It is usually described by two measurements: the flange diameter (Df) and the flange thickness (Tf). https://shengbenzhejiangchina.com.The flange diameter is the overall diameter of the flange, while the flange thickness is the thickness of the flange measured from the outer ring’s surface.
Example of Flanged Ball Bearing Size Description
Let’s take an example of a flanged ball bearing described by the following dimensions: 10x26x8 mm (dxDxB), with a flange size of 30×1.5 mm (Df x Tf).
- The inner diameter (d) is 10 mm, which means the bearing will fit a 10 mm diameter shaft.
- The outer diameter (D) is 26 mm, which is the diameter of the outer ring, excluding the flange.
- The width (B) is 8 mm, which is the thickness of the bearing.
- The flange diameter (Df) is 30 mm, and the flange thickness (Tf) is 1.5 mm.
Selecting the Right Size
Selecting the appropriate size of a flanged ball bearing is crucial for the optimal performance of the application. The bearing’s inner diameter must match the diameter of the shaft it will be mounted on, while the outer diameter and width must fit the housing or the device in which the bearing will be installed. Additionally, the flange size must be considered to ensure it aids in the axial location of the bearing and does not interfere with adjacent components.
Flanged ball bearings come in a wide range of sizes to suit various applications. It is essential to consult the manufacturer’s catalog or a bearing specialist to select the right size bearing for a specific application.
In summary, the size of a flanged ball bearing is described by its inner diameter, outer diameter, width, and flange size. Understanding these dimensions is crucial for selecting the appropriate bearing for a particular application. Properly sized flanged ball bearings will contribute to the efficiency and longevity of the machinery in which they are used.
