- Size Considerations
- Ball Bearing cross reference
- Bore Diameter: In the bearing industry, for bearings with metric diameter holes, you use a standard numbering system. To get the aperture size in millimeters, multiply the aperture size for 04 and above by 5. If the hole is hexagonal, this refers to the dimensions on the plane; if the sphere is tapered, it refers to the smaller diameter.
- Outside diameter: The outside diameter of a ball bearing mainly depends on the specific type. If you use a housed unit bearing, the outside diameter includes the housing; but if you use a flange bearing, the outside diameter does not include the flange portion. The total outside width of the bearing is the width of the outer ring.
- Overall Width: Total ball bearing assembly width including locking ring (if present).

Ball bearings are the most common rolling element bearings, which use balls as rolling elements to maintain separation between the bearing’s moving parts.
The inner ring is installed on the shaft and is a rotating element; the outer ring is mainly used to support and fix the bearing; the ball is the rolling element in the ball bearing, used to reduce friction and make the bearing run smoothly.
The life of a ball bearing depends on the current usage and load conditions. Generally, it can reach thousands to hundreds of thousands of hours.
Research shows that the main cause of ball bearing failure is improper lubrication, followed by incorrect selection, installation errors and problems with the materials used in the bearing itself.

More information you need to know about SLGR ball bearings!
Why are there so many different sizes of SLGR ball bearings?
It is well known that bearing size depends on the size of the shaft and the specific application requirements. Different industries and applications require different sizes of ball bearings to ensure optimal performance. Smaller ball bearings are often used in applications that require greater space efficiency, such as micro devices and precision instruments. Larger ball bearings are often used in heavy industrial equipment, such as agricultural machinery and mining equipment.
How should you correctly measure the size of a SLGR ball bearing?
Vernier calipers make it easy to accurately measure the inside diameter, outside diameter, and width of ball bearings. Here are the steps for accurate measurements:
- First, you need to place the outside hook of the caliper into the inner ring of the bearing, making sure there is a tight fit between the edges.
- Second: Place the ball bearing into the jaws of the caliper and measure the outer diameter to ensure a perfect fit.
- Finally, repeat the above steps to determine the width of the ball bearing.
Once your measurements are complete, you can compare your measurements to the sizing chart to ensure you have selected the correct ball bearing model.
In addition to size, you also need to pay attention to other important aspects of ball bearing numbering, which will help you select the correct ball bearing and improve the performance of your equipment!
- Shield or seal type
- Cage material
- Internal Clearance Level
- Grease temperature
- External coating
Load type, speed requirements, working environment and space constraints need to be considered to ensure you select the correct ball bearing model and size.
