Deep groove ball bearings are the most representative of rolling bearings, versatile. Suitable for high speed or even high speed operation, and very durable, without regular maintenance. This kind of bearing friction coefficient is small, the limiting speed is high, the structure is simple, the manufacture cost is low, easy to achieve higher manufacturing precision. Size range and form of change, used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery and other industries, is the most widely used in the machinery industry, a class of bearings. Mainly subject to radial load, but also can withstand a certain amount of axial load.
Excavator bearing installation and removal methods should be based on excavator bearing structure, size and with the excavator bearing components with the nature of the decision. Installation, demolition of the pressure should be added directly to the excavator bearing ring tight end surface, not through the excavator bearing rolling body transfer pressure, because it will work in the excavator bearing surface indentation, affecting the excavator bearing normal work, And even make the excavator bearing damage. Excavator bearing cages, seals, dust cover and other parts are easy to deformation, installation or removal of the excavator bearing pressure can not be added to these parts.
