I already introduced flanged bearings in another article, where I explained that they mainly include three types: flanged bearing units, flanged ball bearings, and flanged sleeve bearings.
In this flanged bearing size chart guide, the focus is narrower.
I mainly cover standard flanged bearing units, including:
- 2-bolt flange bearing units
- 3-bolt flange bearing units
- 4-bolt flange bearing units
The reason is simple: most flanged bearing units follow standardized dimensions. That means you can compare sizes, select models, and replace them more easily.
For flanged ball bearings, they also follow standard sizes. But in practice, their dimensions are very similar to common bearing types such as deep groove ball bearings. So instead of repeating the same data, you can directly refer to standard ball bearing size charts.
For flanged sleeve bearings, the situation is different. These bearings usually do not follow unified size standards, so there is no consistent chart to list. That’s why they are not included in this guide.
After you check the flange bearing sizes and select a suitable model, the next step is straightforward:
You can contact BKZ Industry for pricing and technical support. With 15 years of manufacturing experience in flanged bearings, we can help you confirm specifications, materials, and application suitability.
Now, let’s move to the flanged bearing size chart.
Tip: The table is quite long. To save time, use:
- Ctrl + F (Windows)
- Cmd + F (Mac)
Then, enter the keywords like bearing number or sizes. This helps you quickly find the exact bearing number or dimensions you need.
And one page cannot cover all the sizes, you can contact BKZ Industry with the information you have to get the correct bearing number or sizes.
