Understanding the 6208 Bearing: Construction and Design

A 6208 bearing is a deep-groove ball bearing with a single row of balls. It is composed of three primary components:

• Inner ring: The inner ring rotates with the shaft.
• Outer ring: The outer ring remains stationary and provides support for the balls.
• Balls: The balls roll between the inner and outer rings, reducing friction and facilitating smooth rotation.

The 6208 bearing is characterized by an open design, allowing for easy lubrication and maintenance. It is typically made from high-quality steel and can withstand substantial radial and axial loads.

Bearing Dimensions and Specifications

6208 bearings are standardized according to ISO and DIN specifications. Their dimensions and other key characteristics are as follows:
