Four row chrome steel cylindrical roller bearing with brass or steel cage

Race:we use the most advanced technology-cold extrusion process for all bearing sizes.Different with others, our race will make two or three times temper to guarantee its high precision.
Rolling element:we use the rolling technology to process the roller and the steel ball of high precision bearing sizes,the most advantage of our technology is to promote operational and productive efficiency.So the productive cost of all bearing sizes will also be lower.At the same time,our technology can prolong the bearing sizes working life.The hardness and the dimension stability will also promote
Steel cage:in order to avoid cracks and guarantee the hardness,we use pattern "high temperature+long time", our cage of high precision bearing sizes have reached advanced level in china at surface abrasion resistance and fatigue strength.
