When it comes to choosing the right bearings for your machinery or equipment, understanding their dimensions is crucial. In this article, we will delve into the dimensions of 6001-2RS bearings, a popular type of bearing used in various industries. Whether you are a novice or an experienced professional, this guide will provide you with valuable insights.

What are 6001-2RS Bearings?

6001-2RS bearings belong to the deep groove ball bearing family. They are designed to withstand radial and axial loads, making them suitable for a wide range of applications, including motors, pumps, and automotive components. The “6001” denotes the bearing’s size and series, while “2RS” indicates that it has rubber seals on both sides, providing protection against contaminants.


The dimensions of a 6001-2RS bearing are critical for ensuring compatibility and optimal performance. Here are the key dimensions you need to consider:

1. Outer Diameter (OD)

The outer diameter of a 6001-2RS bearing is typically 28mm. This measurement is crucial as it determines the fit of the bearing in the housing or shaft. It is essential to ensure that the outer diameter matches the specifications provided by the manufacturer.

2. Inner Diameter (ID)

The inner diameter of a 6001-2RS bearing is commonly 12mm. This dimension is crucial as it determines the fit of the bearing on the shaft. It is important to select a bearing with an inner diameter that matches the shaft diameter accurately.

3. Width

The width of a 6001-2RS bearing is typically 8mm. This measurement is vital as it determines the load capacity and stability of the bearing. Choosing the appropriate width ensures that the bearing can adequately support the applied loads.

4. Ball Diameter

The ball diameter of a 6001-2RS bearing is usually 4mm. This dimension is important as it affects the bearing’s load-carrying capacity and overall performance. The ball diameter should be carefully considered to ensure optimal functioning.


Understanding the dimensions of 6001-2RS bearings is crucial for selecting the right bearing for your specific application. By considering the outer diameter, inner diameter, width, and ball diameter, you can ensure compatibility and optimal performance. Always refer to the manufacturer’s specifications and consult with experts if needed. Choosing the right bearing dimensions will contribute to the efficiency and longevity of your machinery or equipment.
