The main feature of high speed wire rod production line is high reliability of continuous operation of mill. Due to high unit production,it is required that the bearing used in mill must have higher reliability than normal bearing during in specified inspection.Therefore,the high speed wire rolling mill bearings must meet continuous operation requirements under high-speed and high-impact conditions. Making bearings that can withstand constant production and the prohibition of bearing damage becomes a critical standard for the manufacturers who produce bearings for high-speed wire rolling mills.
Due to the work characteristic of high-speed wire rod mill,the requirement to matched bearing is more strictly.Because high rotation speed of rolling mill,heavy load and large impact force must be hold by bearing,the bearing quality must be reliable and high.The bearings used in speed-increase box,split-speed box， pinch roll， roll box and laying head of finishing mill are imported from west countries and were expensive.
High speed wire rod mill bearings manufactured by Jiayu have steadily been used in high speed wire finishing mill and improved that they have high quality and competitive price compared with bearings produce by American and Germany.There are third，forth，fifth，sixth generation of high speed wire rod mill,and our bearings are suitable fifth and sixth generation finishing mill.
Key technology
1.Considering lubrication，centrifugal force and slip，as well as impact force caused by heavy load.
2.Higher reliability
3.Improved cage design
4.Improved groove curve
