Glossary - Precision

Accuracy; exactness; how closely the dimensions of the bearing conform to the stated dimensions.

For example; An inner diameter may be stated as 8.000 mm +0/-0.008mm which would mean that the inner diameter can be anywhere from 7.992 to 8.000mm. A more precise version of this bearing would be one with an inner diameter of 8.000mm +0/-0.003mm, which could also be represented as 7.997 to 8.000mm.
