Double Row Deep Groove Ball Bearings: A Comprehensive Guide

Double row deep groove ball bearings are a type of rolling-element bearing that is used in a wide range of applications. They are known for their high load capacity, long service life, and low maintenance requirements.

Types of Double Row Deep Groove Ball Bearings

There are two main types of double row deep groove ball bearings:

• Open bearings have no seals or shields, which makes them easy to clean and inspect. However, they are not as well-suited for applications where contamination is a concern.
• Sealed bearings have seals or shields that protect the bearing from contamination. They are more expensive than open bearings, but they can provide longer service life in harsh environments.
