Excavator is special bearings as imports engineering machinery gradually introduced the rise, the company on the basis of imported bearings, to absorb the development form a series of products, so as to achieve import bearing standard ofperformance, to fill the gaps in the product in the domestic.

        The bearing contact Angle is larger, so it can be subject to pure axial load or predominantly axial load of the radial and axial load, due to the use of steel ball quantity is more, so than other bearing load increases with size standard, widely used in all kinds of imported construction machinery, excavators.
