Products Contained: 30pcs ball bearings (I.D. = 3 mm, O.D. = 10 mm, Thickness = 4mm)
Material: Deep groove ball bearings are made of carbon steel. High hardness, high load capacity, and wear resistance
Design: 623ZZ ball bearings are sealed with rubber on both sides to avoid the entry of impurities and save lubricant
Applications: Suitable for many kinds of industrial equipment, such as computer hard drives, motors, and instrumentation equipment, etc
High Efficiency: Small frictional resistance, high speed, can be used to withstand radial load or radial colleague role of the combined load of the machine, can also be used to withstand the axial load on the body
