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.
