Understanding 6203-2RS Bearing Construction

6203-2RS bearings belong to the 6000 Series of deep-groove ball bearings, which are characterized by their versatility and suitability for a wide range of operating conditions. These bearings consist of the following components:

• Inner ring: The inner ring is the stationary part of the bearing that fits onto the shaft.

• Outer ring: The outer ring is the rotating part of the bearing that houses the rolling elements.

  

  

• Rolling elements: The rolling elements, typically balls, are the intermediaries between the inner and outer rings and facilitate smooth rotation.

• Cage: The cage, also known as a separator or retainer, keeps the rolling elements evenly spaced and prevents them from contacting each other.

• Seals: The 2RS suffix in the bearing designation indicates that the bearing is equipped with two rubber seals on both sides. These seals protect the bearing from contamination and retain the lubricant.

  

Bearing Dimensions and Load Capacity

The 6203-2RS bearing has the following dimensions:

The load capacity of a bearing refers to its ability to withstand forces without permanent deformation or failure. The dynamic load capacity (Cr) of a 6203-2RS bearing is 11.2 kN, while its static load capacity (Cor) is 7.35 kN. These values represent the maximum loads that the bearing can support under rotational and stationary conditions, respectively.
