We have created a list of the most popular sizes to make it quicker and easier for you to identify and purchase the exact ball bearing for your application. Simply click on your size and view our current selection.

Place the ball bearing on a flat and clean surface. Take the caliper or micrometer and gently insert its jaws or anvils into the bore of the bearing. Ensure that the measuring tool is at a right angle to the bore. Once positioned correctly, read, and record the measurement displayed on the caliper or micrometer. This value represents the bore size or the Inner Diameter (ID) of the bearing.

Bearings very rarely have a prefix code. However, you may come across one that does. The prefix is used to highlight the parts used by the manufacturer in the design of the bearing. In our example where we have a Prefix of (S) it tells us that the bearing was made using stainless steel. Below are a couple of common examples

Typically bearing codes are comprised of a ‘basic number’ and depending on the bearing they can have supplementary codes at the beginning or the end of the basic number. These are the prefix and suffix codes.

Before measuring, it’s important to identify the type of ball bearing you have. There are several common types, such as deep groove ball bearings, angular contact ball bearings, and thrust ball bearings to mention a few. Each type has its own unique design, and it is essential to recognize the correct type you have for accurate measurements. For more information on the different types of ball bearings available please see our Ball Bearings Guide
