Understanding the 6203-2RS Bearing

Construction and Design

The 6203-2RS bearing is a single-row, deep-groove ball bearing characterized by its compact size and high load capacity. It comprises the following key components:

• Inner race: The inner ring rotates with the shaft.
• Outer race: The outer ring remains stationary and provides support to the bearing.
• Balls: Steel balls positioned between the races transmit the load.
• Cage: A metal cage separates and guides the balls, ensuring even load distribution.
• Seals: Rubber seals on both sides of the bearing prevent the ingress of contaminants and retain lubrication.

Operational Principles

The 6203-2RS bearing operates on the principle of rolling friction, where the balls roll smoothly between the races, minimizing friction and wear. Its deep-groove design enables it to accommodate both radial and axial loads, making it suitable for a wide range of applications.
