Material: Microporous bakelite cage is made of cotton cloth as the base material, phenolic resin as the adhesive, and thermal reactive foaming agent as the pore
forming agent and then becomes the tubular material after hot rolling and post-curing technology.
Working principle of microporous bakelite cages: After being processed into the cage and immersed in lubricating oil, we can transport the lubricating oil to the cage surface
by capillary action of cotton fiber, and the controllable lubricating oil can be supplied to the working part of the bearing during bearing operation to achieve high precision
and long service life of the bearing.
