- 品牌：NSK
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 average of one new product coming out every two days.
轴承的加热温度由轴承的尺寸和所需的干扰决定。热装作业应注意以下几点：
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。不要将轴承加热到超过120摄氏度。
1. Do not heat the bearing to more than 120 degrees Celsius.
2。其次。为了防止徐州NSK轴承直接接触油槽的底部，**好考虑将钻头轴承放在两个金属套筒上或提升轴承。
2. Secondly. In order to prevent Xuzhou NSK bearing from directly contacting the bottom of the oil groove,** it is better to consider placing the bit bearing on two metal sleeves or lifting the bearing.
三。将钻头轴承加热到比要求温度高20-30摄氏度，在操作过程中不会冷凝内环，而且很难安装。
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.
第四章安装后，轴承降温，宽度方向收缩。应使用轴螺母或其余适当的拧紧方法来防止内环和轴承台肩之间的间隙。
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.
徐州NSK轴承保持架材料的要求性能：
Xuzhou NSK bearing cage material requirements performance:
尺寸稳定性：稳定，机械强度好
Dimensional stability: stable, good mechanical strength
此外，还需要妥善处理。中文叫轴承。集团总部位于瑞典哥德堡。它是轴承技术和制造业的。双列自动球轴承发明于1905年。1907年，瑞典成立了一家滚珠轴承制造商，被称为瑞典滚珠轴承制造公司。徐州NSK轴承继续发展和服务于世界。根据不同的用途，还要求具有良好的抗冲击性、耐热性和耐腐蚀性。
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.
轴承环和滚动件材料：
Bearing Ring and Rolling Parts Material:
高碳铬轴承钢通常用于环和辊。大多数轴承使用两种等级的钢。大轴承使用3。
High carbon chromium bearing steel is usually used for rings and rolls. Most bearings use two grades of steel. Big bearings use 3.
在抗冲击的情况下，采用铬钢、铬钼钢、镍铬钼钢和渗碳淬火作为轴承材料，从表面到适当层次化提供硬化层。渗碳轴承具有适当的硬化层次化、良好的组织、表面和芯部硬度，其抗冲击性能优于轴承钢。渗碳徐州NSK轴承钢的化学成分一般。
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.
