Precision angular contact bearing cage is a kind of angular contact bearing cages. It is characterized by high speed and high precision. It is mainly used in machine tool spindle, electric spindle and electric tool. Multi-purpose Bakelite cage is replaced by engineering plastic cage in many fields. The use of engineering plastic cage has the advantages of good lubrication, low noise, low cost of mass production, We can also choose different materials with different performance according to different requirements of customers.
