Deep Groove Ball Bearing 6204 Detailed Dimension Information 
The inner diameter of the 6204 bearing is 20 millimeters. It can accommodate shafts with a diameter of 20 millimeters.
The outer diameter of the 6204 bearing is 47 millimeters. This refers to the diameter of the outer ring of the bearing. Make sure that your application space can accommodate the outer diameter of the 6204 bearing.
The 6204 bearing is a common and widely used bearing model. Understanding its inner diameter, outer diameter, and width dimensions is crucial for selecting the appropriate bearing. Based on your application requirements, load, speed, temperature, and quality criteria, choose the suitable size of the 6204 bearing for your application to ensure good performance and reliability.
The 6204 bearing is typically composed of an inner ring, outer ring, ball elements, and a cage. The groove in the raceway is slightly larger than the radius of the steel balls. Due to the point contact between the balls and the raceway, the 6204 bearing can withstand both axial loads in both directions and radial loads. It is commonly used in pairs under normal conditions to minimize the internal axial forces caused by the load and to primarily handle radial loads.
The sealing covers for the 6204 bearing mainly come in three types: ZZ, 2RS, and OPEN.
6204 OPEN, 6204 ZZ, and 6204 RS are different outer cover modes of the bearing. In this article, we will introduce these outer cover modes to help you choose the appropriate bearing protection method that suits your needs.
The 6204 OPEN type bearing cover is a design without a cover, allowing the internal components of the bearing to be exposed to the external environment. This design makes the bearing more susceptible to contamination from dirt, dust, and other external particles.

6204ZZ refers to the 6204 bearing with metal shields as the outer cover. The metal shields effectively block dust, contaminants, and other external particles from entering while retaining the lubricant within the bearing.

6204 RS refers to the 6204 bearing with rubber seals as the outer cover. The rubber seals provide enhanced protection by effectively blocking moisture, dust, and other contaminants from entering. This sealing method is commonly used in harsh environments and applications that require stricter protection.
Application environment: Determine the potential sources of contamination and other external particles in your application environment. Based on the environmental conditions, choose between open type, metal shields, or rubber seals to provide the appropriate protection.
Precision and speed requirements: Consider the precision and speed requirements of your application. Open type bearings are typically suitable for low precision and lower speed applications, while metal shields and rubber seals offer higher protection and are suitable for medium and high precision requirements.
Maintenance requirements: Consider your maintenance needs for the bearings. Open type bearings require regular cleaning and lubrication, while metal shields and rubber seals can reduce maintenance requirements.
6204 OPEN, 6204 ZZ, and 6204 RS are different outer cover modes of bearings that provide varying degrees of protection and support. Depending on your application environment, precision and speed requirements, as well as maintenance needs, choose the appropriate outer cover mode to ensure the normal operation of the bearing and extend its lifespan.
