Deep groove ball bearings is steel ball bearings. NSAR bearings’s numbering system utilizes a basic bearings number to indicate the appropriate bearings series,and a complementary set of prefix and suffix designations which allow a complete description of any bearings configuration.
Our deep groove ball bearings are engineered to ABEC precision to provide reliable performance in a wide range of applications. Made from high-grade steel and produced to ABEC standards, these bearings ensure smooth operation, reduced noise and excellent durability under radial and axial loads.
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 the NSAR quality bearing catalog.

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, 7 and 9 – 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.
