What are bearing dimensions?
Bearings are measured by their inner diameter, outer diameter, and width; the size of a bearing is normally listed as such: ID x OD x W. These measurements are normally taken in millimeters, but can be converted to inches.
What is bearing dimension series?
A bearing number is composed as follows. The width series symbol and diameter series symbol are combined and called the dimensional series symbol. For radial bearings, the outside diameter increases with the diameter series symbols 7, 8, 9, 0, 1, 2, 3, and 4. Usually, 9, 0, 2, and 3 are the most frequently used.
How do you find the OD of a bearing?
You should wiggle the calipers inside the bearing inner ring to make sure they sit across the widest part. Repeat the process using the external measurement side of the caliper to calculate the outer diameter of the bearing. This time, roll the calipers in a closing direction to obtain the outer diameter measurement.
What does UU mean on a bearing?
DU and UU are suffix codes that are used by some manufacturers (I think) to denote rubber seals. The ‘2RS’ code is not a universal designation, although it is used by more than one manufacturer. This is a 6004-UU bearing. AFAICT ‘UU’ = ‘LLB’ ~ ‘2RS’
How to calculate bearing dimensions?
You can measure the dimensions of a bearing by using a vernier calliper like the one below or measuring accurately with a ruler. All bearings will have a width, an inner diameter and an outside diameter. Once you have determined the dimensions of your bearing, you can use our bearing search tool to find the correct bearing.
