New Xuzhou NSK bearing industry has spread all over the world, covering 130 countries. It produces more than 500 million bearings a year and has a global sales network. In addition, the group is committed to research and development in the bearing industry, with an ***erage of one new product coming out every two days.
The heating temperature of the bearing is determined by the size of the bearing and the interference required. Hot loading operation should pay attention to the following points:
1. Do not heat the bearing to more than 120 degrees Celsius.
2. Secondly. In order to prevent Xuzhou NSK bearing from directly contacting the bottom of the oil groove,** it is better to c***ider placing the bit bearing on two metal sleeves or lifting the bearing.
Three. Heating the bit bearing to 20-30 degrees Celsius higher than the required temperature will not condensate the inner ring during operation and is difficult to install.
Chapter IV After installation, bearing cooling, width direction contraction. Shaft nuts or other appropriate tightening methods should be used to prevent clearance between the inner ring and the bearing shoulder.
Xuzhou NSK bearing cage material requirements performance:
Dimensional stability: stable, good mechanical strength
In addition, it needs to be properly handled. Chinese is called bearing. The headquarters of the Group is located in Gothenburg, Sweden. It is a bearing technology and manufacturing industry. Double row automatic ball bearing was invented in 1905. In 1907, Sweden established a manufacturer of ball bearings, known as the Swedish Ball Bearing Manufacturing Company. Xuzhou NSK bearings continue to develop and serve the world. According to different uses, good impact resistance, heat resistance and corrosion resistance are also required.
Bearing Ring and Rolling Parts Material:
High carbon chromium bearing steel is usually used for rings and rolls. Most bearings use two grades of steel. Big bearings use 3.
In the case of impact resistance, chromium steel, chromium-molybdenum steel, nickel-chromium-molybdenum steel and carburizing and quenching are used as bearing materials to provide hardening layer from surface to proper level. Carburized bearing has proper hardening hierarchy, good structure, surface and core hardness, and its impact resistance is better than that of bearing steel. The chemical composition of carburized Xuzhou NSK bearing steel is general.
