Composed of basic components of rolling bearings

Rolling bearings usually consists of the following four basic components:
    Inner ring, outer ring, cage and rolling - on the heart or the heart to the thrust bearing (inner or outer rings may be referred to), axes ring, seat ring, cage and rolling - on the thrust or radial thrust bearing (shaft washer or seat may be referred to as washers).
    Rolling bearings with the rolling body is the basic structural features, a small number of species of rolling positions in order to save space, or for rolling into more, you can not take the outer ring or inner ring, without inner and outer rings, with or without cage , but all must have a rolling element bearing.
    Inner ring is usually installed in the shaft or shaft, the outer ring or bearing seat installed in the hole, and rolling the assembly including the outer ring or the shaft, between the seat ring. External load or through the rolling axis by the inner circle or ring passed out seat, or seat by the outer or inner ring or shaft to the transmission cycle, the two sides achieved by rolling the relative rotation. Cage used to be rolling off to avoid contact between rolling elements, because direct contact with the rolling body is roughly at the relative speed of rolling single to 1 times the scrolling speed, which can cause abrasions rolling.
    Most of the strengths and weaknesses of rolling and rolling to the existence of, for example, constitute a rolling friction with rolling elements, the static and dynamic friction coefficient is low, high transmission efficiency, the axial size is small, but it also constitutes a higher pair contact ("point" contact or "line" contact), making the bearing stiffness, vibration and noise is less than the quality of some types of plain bearings, radial size as well.
