Microporous Bakelite Cage Bearing Spare Parts 71902 Non Customized
Microporous bakelite cage
Technical parameters of Microporous bakelite cages:
Inner diameter size : Ф25mm～Ф90mm
Outer diameter size : Ф35mm～Ф100mm
Applicable speed : 1000～60000r/min
Applicable temperature : －50～＋120℃
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.
