The inner ring-is mounted on the axle neck;
The outer ring $number is installed in the bearing hole of the machine or part;
Rolling body $number to achieve rolling friction;
Cage-evenly spaced rolling body.
In practice, the structure of inner and outer ring, dustproof and sealing ring can be selected according to the specific use requirement. The commonly used materials for the manufacture of rolling bearings are materials such as high strength and contact fatigue strength of gcr15,gcr15simn,gcr6,gcr9 and good abrasion resistance and impact toughness.
