Understanding Bearing Dimensions The Case of the 6204 Bearing

Bearings are essential components in many mechanical systems, ensuring smooth and efficient movement. Among the various types of bearings, the 6204 bearing series is a common choice in different applications due to its reliability, versatility, and ease of maintenance. This article will delve into the dimensions of the 6204 bearing, its applications, and its significance in various fields.

What is a 6204 Bearing?

The 6204 bearing is a deep groove ball bearing, which is characterized by its simple design and ability to handle both radial and axial loads. The 6204 designation refers to a specific size in the series, defined by standard dimensions set by the International Organization for Standardization (ISO). The 6204 bearing typically has a bore (inner diameter) of 20 mm, an outer diameter of 47 mm, and a width (thickness) of 14 mm. These dimensions make it suitable for a wide range of applications, particularly in automotive, industrial machinery, and household appliances.

Dimensions Breakdown

Understanding the dimensions of the 6204 bearing is crucial for its application. Here’s a detailed breakdown of its key dimensions

- Bore (Inner Diameter) 20 mm - Outer Diameter 47 mm - Width (Thickness) 14 mm - Dynamic Load Rating (C) approximately 10.2 kN - Static Load Rating (C0) approximately 5.35 kN - Limiting Speed This varies depending on the specific application and lubrication, but it can generally exceed 10,000 RPM under ideal conditions.

These specifications show that the 6204 bearing is robust enough to support significant loads while maintaining high-speed performance, making it a reliable choice for various uses.
