DescriptionThe deep groove ball bearings, which are 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.Features-Color: Silver.-Material: ball bearing steels -Size: About 1.30X1.30X0.40cm/ 0.51X0.51X0.16inch.- It has uniform hardness and wear resistance, high temperature resistance and long service life.- Smooth surface, good hand feeling, corrosion-resistant and wear-resistant bearings.- The rotation is uniform during operation, and it works in coordination with the machine to improve efficiency.- The double-sided cover is sealed and can be used in the printer to ensure dustproof during high-speed printing.- Manufactured with premium material that can be used for a long term.
