We have special facilities to produce large, outsize andNon-standard bearings, of bore diameters up to 4500mm.Our long-life bearings' which are designed with the unique Rolling Bearing Limit Design Method, are widely used for heavy equipments in metallurgy, oil drilling, power generators, ships, port cranes, mining machines, plastic machines, chemical machines and military applications. The unique method breaks through the hundreds-of-years design method. Firstly, strength boundary value is determined. Secondly, another set of design calculation formulas are deduced so that the determined rolling element dimension infinitely approach the strength boundary value (limit concept in the mathematics). Accurate calculation within three times can achieve the optimum mathematics result. Thousands of updated long life Heavy-duty bearings and slewing bearings with O. D 150--4339.2mm in 2,3,5,8, N, QJ have been developed and produced by us. Compared with bearings of traditional method, our bearings'working life can be improved to one to four times.
