6300 series deep groove ball bearings are a widely used rolling bearing type. It has a simple structure and is easy to achieve high precision. The bearing has an inner diameter of 10mm and an outer diameter of 35mm, and can withstand radial load, axial load or combined load. Due to its high rotational speed and durability, it is often used in applications such as leather processing equipment, wire stripping machines and chillers.
