DescriptionThe deep groove ball bearings, which is the most widely used rolling bearing. It is characterized by low friction resistance and high rotation speed. Low noise and vibration. Pre-lubricated, it can be used for mechanical parts that can bear radial load or combined load of radial and axial simultaneously. It can also be used for mechanical parts that bear axial load, such as small power motors, Automotive and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.Features- Color: Silver. - Material: Steel. - Size: 1.3 x 1.3 x 0.5cm/ 0.51 x 0.51 x 0.21 inch. - Bearing material: Bearing material is divided into bearing steel, high carbon steel, bright metallic luster, longer service life and higher precision. - Deep groove ball bearings are mainly subjected to radial loads and can also bear both radial and axial loads. - This type of bearing has small friction coefficient, high limit, simple structure, low manufacturing cost and easy to achieve high manufacturing precision. - Both sides of the detachable single lip seal prevent contamination and maintain lubrication in the manufacturing process. - Dimensional range and form vary, used in precision instruments, low noise motors, automobiles, motorcycles and general machinery, etc. It is a widely used type of bearing in the machinery industry.
