Miniature ball bearings are ideal for a wide variety of light duty instrument and precision applications. Miniature deep groove ball bearings are metric series, outer diameter is less than 9mm; Inch series, all kinds of bearings with outer diameter less than 9.525mm, the main materials are carbon steel, bearing steel, stainless steel, plastic, ceramic, etc., among which the minimum inner diameter can be 0.6mm, and the general inner diameter is 1mm.
Deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages.
It mainly bears pure radial loads, but also can bear joint loads. When it is subjected to pure radial load, its contact Angle is zero. When it has a larger radial game, that is, it has angular contact bearing performance, which can withstand a larger axial load. Deep groove ball bearing has small friction coefficient and high limit speed, so it has more advantages than thrust bearing when axial load is rotating at high speed. But because its aligning performance is limited, the concentricity of bearing installation should be high, otherwise it will affect the balance of its operation, increase the bearing stress, and thus shorten the working life.
Main Application：
It is suitable for all kinds of industrial equipment, small rotary motor and other high speed and low noise fields, such as: office equipment, micro motor, instrument, laser engraving, small clock, soft drive, pressure rotor, dental drill, hard disk motor, stepping motor, video recorder drum, toy model, computer cooling fan, bill counting machine, fax machine and so on related fields.
Advantages of deep groove ball bearings:
Deep groove ball bearing has the advantages of low manufacturing cost, simple structure, variety and so on. It is widely used in various industries and is one of the more commonly used bearings. It has the following characteristics:
1. Small friction coefficient, high speed.
2.The size range is wide, with a certain aligning ability.
3.Simple structure, low manufacturing cost, mass production, can achieve high precision.
4.Can bear large radial load, when the radial clearance increases, can bear two directions of alternating axial load.
5.In reasonable maintenance and use of the environment of high durability, low maintenance cost.
