It is one of the most widely used rolling ball bearings. Its characteristics is characterized by small friction resistance, high speed, mainly used to bear the radial load, but when increasing the bearing radial clearance gap, has a certain Angle contact ball bearing performance, can bear the diameter, axial combined load, often used for household appliances, Automobile, agricultural machine , machine gear box, general machines, tools, etc. Ball bearings produced by Cixi Hoto Special, with low noise, long life, low rotation accuracy.
