61803 Thin Wall Deep Groove Ball Bearing KOYO Brand 61812 61813 61814

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.
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.

Working principle:

Deep groove ball bearings mainly bear radial load, but also can bear radial load and axial load. When it is only under radial load, the contact Angle is zero. When the deep groove ball bearing has a larger radial clearance, it has the performance of angular contact bearing and can withstand larger axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is very high.

Features:

Deep groove ball bearing are simple in design, non-separable, suitable for high and even very high speeds and are robust in operation, requiring little maintenance.

Single Row Deep Groove Ball Bearings are widely used in household appliances, toys, electric power tools, car motors and other fields. With optimal design, high reliability heat treatment, precision manufacturing processes and high-grade grease, these products perform better on reliability, vibration and noise levels than standard products making them more suitable for electric motor applications. These products can also be applied to most gearbox applications as well.
Deep groove ball bearing is the most common type of rolling bearing.
The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of cages. There are two types of deep groove ball bearing, single row and double row, deep groove ball structure is also divided into sealed and open two kinds of structure, open refers to the bearing without sealing structure, sealing type deep groove ball is divided into dust seal and oil seal. The dust proof sealing cover is made of steel plate stamping, which only prevents dust from entering the bearing raceway. The oil-proof type is contact oil seal, which can effectively prevent the grease spillover in the bearing.
