First, the structure of
Rolling
Rolling the typical structure
Inner Ring
Outer Ring
Rolling in (the ball, roller, needle)
Cage
Some structures can be no inner ring, the outer ring or cage, but
must not be of no rolling.
Second, the characteristics of Rolling
1, the coefficient of friction small and stable, start small
moment
2, the width of small axial
3, radial clearance small, or even disappear adjustable,
high-precision operation.
4, lubrication, maintenance-friendly, simple structure
5, poor ability to withstand impact load
6, large size radial
7, high-speed rotation when the noise
8, lower life expectancy
