Product Information
3000 Series Double Row Angular Contact Ball Bearings
The 3000 Series is a double row angular contact ball bearing range designed for applications where radial loads and axial loads need to be supported at the same time.
Compared with using two separate single row angular contact bearings, a double row design can provide a more compact bearing arrangement while still handling axial loads in both directions. This makes the series a practical option when installation space is limited or when the bearing arrangement needs good rigidity.
The bearings are available in a range of bore and outside diameters to suit different shaft sizes and housing arrangements. Depending on the bearing size and design, open, shielded, or sealed versions can be supplied.
For equipment manufacturers, maintenance teams, and bearing distributors, we can supply standard 3000 Series bearings as well as OEM and customized versions according to drawings, dimensions, load requirements, and operating conditions.

How to Select the Right 3000 Series Bearing
How to Select the Right 3000 Series Bearing
Choosing a bearing by bore size alone is not enough.
Before selecting the final model, check the following:
1. Shaft Diameter
The bearing bore must match the shaft arrangement and required mounting fit.
2. Housing Diameter
Check the outside diameter of the bearing against the available housing bore.
3. Bearing Width
Make sure there is enough axial space for the bearing and any retaining components.
4. Radial Load
Determine the approximate radial load acting on the bearing during operation.
5. Axial Load
Check the magnitude and direction of the axial load.
6. Operating Speed
Compare the actual operating speed with the applicable limiting speed.
7. Temperature
Temperature affects lubricant selection, sealing and internal clearance.
8. Lubrication
Confirm whether the equipment uses grease or oil lubrication.
9. Contamination
Dust, water and other contaminants may require a sealed bearing arrangement.
10. Mounting and Alignment
Shaft and housing tolerances, mounting method and alignment should be considered before installation.
If you do not know the exact bearing number, send us the shaft diameter, housing diameter, bearing width and application details.
