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 simple structure, compared with other easy to achieve high precision, so can be mass production. In addition to the conventional models, it also has a variety of structural variations, such as deep groove ball bearing with dust cover, deep groove ball bearing with rubber ring and deep groove ball bearing with a stop groove and so on.
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.
Miniature Deep Groove Ball Bearings
miniature ball bearing with smallest dimensions
suitable for high radial loads and light axial loads in both directions
suitable for high running accuracy, quiet running, and very high speeds
seal: non-contact gap seal on both sides made of a profiled sheet steel disc (ZZ / 2Z) for higher speeds than with rubber seal
good fixed bearing property, but can also be used as a floating bearing, each in both directions
manufacturers of bearings, such as FAG, KOYO, NSK, SKF,etc.
