The Ultimate Guide to 6207 Bearings: From Basics to Advanced Applications
Introduction
6207 bearings are widely used in various industrial and automotive applications. They are single-row, deep-groove ball bearings with a 35 mm bore diameter, 72 mm outer diameter, and 17 mm width.
6207 bearings account for approximately 80% of all bearing sales, making them one of the most common and versatile bearings available. They are known for their durability, reliability, and ability to withstand high loads.
Understanding 6207 Bearings
Construction
6207 bearings consist of the following components:
-
Inner ring: The inner ring rotates on the shaft.
-
Outer ring: The outer ring is stationary and provides support for the bearing.
-
Balls: The balls roll between the inner and outer rings, reducing friction.
-
Cage: The cage keeps the balls evenly spaced and prevents them from rubbing against each other.
Types
6207 bearings come in various types to suit different applications:
| Type |
Description |
| Open |
No seals or shields |
| Sealed |
Rubber or metal seals on both sides to protect against contaminants |
| Shielded |
Metal shields on both sides to protect against dust and debris |
| Flanged |
Flange on one side for easy mounting |
| Insert |
No inner ring for easy installation on a shaft |
