Rolling bearing scale series code
Rolling Bearing Series Code
The rolling bearing series code is a critical element in identifying and classifying bearings. It consists of two main components: the diameter series code and the width (or height) series code. These codes help determine the dimensions and performance characteristics of the bearing, making it easier for engineers and technicians to select the right bearing for specific applications.
The diameter series refers to the outer diameter scale that corresponds to a given nominal inner diameter. This series is typically represented by numbers such as 7, 8, 9, 0, 1, 2, 3, 4, 5, etc., and indicates the relative size of the bearing. For example, a higher number generally means a larger outer diameter, which can affect load capacity and speed capabilities.
The width series relates to the width of the bearing, which corresponds to its diameter series. This is usually indicated by numbers like 8, 0, 1, 2, 3, 4, 5, 6, etc. The width series helps define the overall dimensions of the bearing, influencing factors such as axial load capacity and space requirements.
For thrust bearings, instead of a width series, there is a height series that corresponds to the width of radial bearings. This series is marked with numbers such as 7, 9, 1, 2, and so on, helping to identify the axial dimension of the bearing.
Understanding these series codes is essential for anyone involved in machinery maintenance, design, or procurement. Proper identification ensures that the correct bearing is selected, reducing the risk of failure and increasing the lifespan of mechanical systems.
