Understanding 6302 2RS Bearing Dimensions

Bearings are essential components in various mechanical systems, providing support, reducing friction, and enabling smooth rotation. One commonly used type of bearing is the 6302 2RS bearing. In this article, we will delve into the dimensions, specifications, and applications of the 6302 2RS bearing, as well as its importance in machinery.

What is a 6302 2RS Bearing?

The 6302 designation indicates a specific type of deep groove ball bearing. The 2RS suffix signifies that the bearing is equipped with rubber seals on both sides, which helps in retaining lubrication and preventing the entry of dirt and moisture. This makes the 6302 2RS bearing particularly suitable for applications where environmental contaminants are a concern.

Dimensions of 6302 2RS Bearing

The dimensions of the 6302 2RS bearing are standardized and essential for ensuring compatibility with other components in mechanical assemblies. The key dimensions are as follows

- Inside Diameter (ID) 15 mm - Outside Diameter (OD) 42 mm - Width (W) 13 mm

These measurements conform to the ISO standards, making the 6302 2RS bearing a widely accepted choice across various industries.

Load Ratings

Load ratings are critical when selecting a bearing for specific applications. The 6302 2RS bearing has dynamic and static load ratings that define how much load the bearing can support while maintaining its functionality. The dynamic load rating (C) is typically around 13,000 N, while the static load rating (C0) is approximately 6,400 N. Understanding these values helps engineers select the right bearing for their mechanical requirements, ensuring durability and performance.

Rotational Speed

The 6302 2RS bearing is capable of handling moderate to high-speed applications. The permissible speed at which the bearing can operate largely depends on the type of lubrication and operating conditions. For grease lubrication, the maximum operating speed can reach around 15,000 RPM. It is crucial to consider these parameters to prevent overheating and potential bearing failure.
