Deep groove ball bearing consists of an outer ring, an inner ring, a set of steel ball and a set of cage. 6000 series bearings are deep groove ball bearings, inner diameter (d) is 10mm, outer diameter (D) is 26mm, thickness (B) is 8mm. Open type deep groove ball bearing is suitable for high speed and high speed running, and very durable, need not often maintenance. These bearing small friction coefficient, high limit speed, size range and variety in form, used in precision instrument, low noise motors, automobiles, motorcycles and general machinery and other industries, is the most widely used type of bearings in machinery industry. Mainly bear radial load, also can withstand a certain amount of axial load.
