Deep groove ball bearings are the most widely used type of rolling element bearing, accounting for approximately 80% of all bearing applications. They are characterized by their simple design, which consists of an inner ring, outer ring, and a set of balls that roll between the two rings. Despite their simplicity, deep groove ball bearings offer high load capacity, long service life, and low maintenance requirements.
Deep groove ball bearings are available in a variety of types and sizes to meet the specific requirements of different applications. Some of the most common types include:
Deep groove ball bearings are also available in a wide range of sizes, from miniature bearings with bore diameters of just a few millimeters to large bearings with bore diameters of over 1 meter.
