K type bearing cage component related issues

K type bearing cage components by centripetal needle bearing and thrust bearing components of bearing unit, the compact structure small volume, rotation of high precision, high in can bear radial load at the same time absorb a certain amount of axial load. A variety of forms, wide adaptability and product structure, easy to install. K type bearing cage components, is very important to bearing life and reliability of advanced heat treatment technology and equipment, such as controlled atmosphere protection heating, double refinement, bainite hardening, such as low coverage, many technical problems research failed to make a breakthrough, is actually the deep groove ball bearing a form, characteristic is its outer diameter for spherical surface, can match into the corresponding concave spherical bearing self-aligning effect. K type bearing cage components caused by sliding friction bearing heat and wear and tear, especially under the condition of high temperature operation, the effect of inertial centrifugal force increased friction and wear with fever, a bracket will be caused serious burns or fracture, the bearing can work normally. Therefore, request retainers material besides have a certain strength, must also be good thermal conductivity, low friction factor, good abrasion resistance, impact toughness, density is small and linear expansion coefficient and rolling body is close.
