Whether you are building high-speed machinery or need reliable motion in industrial applications, our deep groove ball bearings offer the perfect balance of precision and performance, check out theNSAR quality bearing catalog.

ABEC Rating: A Tool in Bearing Selection

ABEC stands for the Annular Bearing Engineers Committee. It is a standardized rating system used to measure the accuracy and tolerance levels of ball bearings.
The ABEC scale helps users understand how accurately a bearing is manufactured, especially in the following areas:
Dimensional tolerances
Roundness
Surface finish
Noise and vibration levels
ABEC ratings are usually odd-numbered:ABEC 1, 3, 5, 7e9– the higher the number, the tighter the tolerance and the higher the accuracy.
Here is a brief analysis:
ABEC 1: Lowest precision, suitable for general use
ABEC 3: Common in low-cost applications
ABEC 5: High precision, used for higher quality machinery
ABEC 7: High precision, used in applications such as high-speed tools or instruments
ABEC 9: Extremely high precision, often used in aerospace or advanced scientific equipment
Note: ABEC grades do not cover everything, such as material quality, load rating or lubrication. Therefore, a higher ABEC grade does not necessarily mean it is the best bearing for all applications. When purchasing bearings, you should still choose the most suitable precision for your use to achieve the greatest effect.
