Understanding Single Row Deep Groove Ball Bearings A Size Chart Guide

Single row deep groove ball bearings are one of the most commonly used types of rolling-element bearings. Their design enables them to accommodate both radial and axial loads in a wide range of applications, making them integral to various machinery and equipment. This article will delve into the structural characteristics of these bearings, discuss their applications, and provide insights into a size chart for better understanding.

Design and Structure

Single row deep groove ball bearings consist of an inner ring, an outer ring, a ball complement, and a cage to separate the balls. The deep groove design allows these bearings to support higher radial loads compared to standard deep groove designs. The key features of these bearings include

1. Universal Application Due to their versatile design, they are suitable for use in various industries, including automotive, aerospace, and manufacturing. 2. Standardized Sizes These bearings are produced in a variety of standard sizes, making them easily obtainable and interchangeable. This standardization allows manufacturers to design machinery with predictable outcomes in terms of performance and durability.

3. Low Friction Design The rolling contact between the balls and the inner and outer rings leads to low friction, which enhances efficiency and reduces heat generation during operation.

Size Chart Overview

The size chart for single row deep groove ball bearings typically includes key dimensions such as the bore diameter (d), outer diameter (D), width (B), and various load ratings. Here’s a breakdown of what each of these dimensions means

- Bore Diameter (d) This is the internal diameter of the bearing, which is crucial when considering the shaft size that the bearing will fit onto.

- Outer Diameter (D) The external diameter of the bearing impacts the equipment's layout and might dictate the space required for installation.

- Width (B) The width affects the overall size and load capacity of the bearing. Generally, a wider bearing can support a greater load.

- Dynamic and Static Load Ratings These ratings (often denoted as C and C0, respectively) indicate the maximum load that the bearing can support dynamically (while in motion) and statically (when stationary).

A typical size chart might look something like this

| Bearing No. | Bore (d) | Outer Diameter (D) | Width (B) | Dynamic Load (C) | Static Load (C0) | |-------------|----------|--------------------|-----------|------------------|-------------------| | 6200 | 10 mm | 30 mm | 9 mm | 6.9 kN | 3.6 kN | | 6300 | 10 mm | 35 mm | 11 mm | 7.8 kN | 5.6 kN | | 6400 | 20 mm | 40 mm | 12 mm | 10.5 kN | 8.5 kN |
