<

Too heavy to develop the world's largest capacity rolling mill oil film bearing Oil film bearings, as the heart of the mill, require large load capacity and high running accuracy. The world's largest wide-thick plate rolling mill oil film bearing developed by Too Heavy Oil Film Bearings Branch not only has the largest bearing capacity in the world, but also has the largest length and diameter in the world. The working diameter is 1670mm, the working length of the bearing is 1452mm, and the single bearing is the largest. The load is 7,247 tons. In the spring of 2013, the Taishi Film Division successfully developed the world's largest bearing capacity of heavy plate rolling mill oil film bearings.

It is understood that the oil film bearing as the heart of the mill requires a large load capacity and high running accuracy. The world's largest wide-thick plate rolling mill oil film bearing developed by Too Heavy Oil Film Bearings Branch not only has the largest bearing capacity in the world, but also has the largest length and diameter in the world. The working diameter is 1670mm, the working length of the bearing is 1452mm, and the single bearing is the largest. The load is 7247 tons; relying on the formed oil film, it can withstand the rolling pressure of the rolling mill and ensure the low energy consumption and high precision operation of the roll. It plays a crucial role in improving the precision of the steel plate. It adopts the most advanced technology in the world today. It can meet the current use of the largest 5.5-meter mill at home and abroad, and has reached or exceeded the current level of similar foreign products in terms of product structure, manufacturing precision and product life.

According to the person in charge of the related department, the world’s largest wide-thick-plate rolling mill oil film bearing was produced for Nanjing Iron & Steel Co., Ltd. Its successful trial marks a new breakthrough in the design and manufacturing level of the oil film bearing, not only breaking the foreign The company’s long-term monopoly has opened up a much broader market for too heavy oil film bearings.
