江苏nsk轴承滚针轴承外圈与轴承座孔紧密配合。当内圈和轴松动时，轴承可以首先安装在轴上。当江苏nsk轴承针轴承环与轴或轴承座孔紧密对准时，使用专门设计的安装缸将轴压到轴或轴承座上。
the outer ring of jiangsu nsk bearing needle bearing is closely cooperated with the bearing seat hole. when the inner ring and shaft are loose, the bearing can first be installed on the shaft. when the jiangsu nsk bearing needle ring is closely aligned with the shaft or bearing seat hole, a specially designed mounting cylinder is used to press the shaft to the shaft or bearing base.
江苏nsk轴承滚针轴承的安装由于内圈和外圈而方便地安装在轴或轴承座上。此时，当轴插入轴承箱时，应尽量保持同心度，以防止滚子和滚道磨损。
the installation of nsk bearing needle bearing in jiangsu is conveniently installed on the shaft or bearing base because of the inner ring and outer ring. at this time, when the shaft is inserted into the bearing box, the concentricity should be kept as far as possible to prevent roller and raceway wear.
当江苏nsk轴承的尺寸较大时，由于轴承的安装力和重载，轴承垫圈或轴承座难以提前安装。轴承内圈或轴承座应预先安装。安装重、冷条件很困难。在安装过程中，应严格控制加热温度。当加热轴承时，加热温度不应超过1200度，通常在80～1000摄氏度。轴承不能用防尘盖或密封圈加热，否则会失去润滑剂。加热方法可以通过电感应加热和油浴加热来加热。
when the bearing size of jiangsu nsk is large, the bearing gasket or bearing block is difficult to be installed ahead of time due to the installation force and heavy load of the bearing. bearing inner ring or bearing seat should be installed in advance. it is difficult to install heavy and cold conditions. during the installation process, the heating temperature should be strictly controlled. when heating bearings, the maximum heating temperature should not exceed 1200 degrees, usually at 80~1000 degrees celsius. bearing can not be heated with dustproof cover or sealing ring, otherwise lubricant will be lost. the heating method can be heated by electric induction heating and oil bath heating.
江苏nsk轴承通常由低合金和高纯度淬硬铬钢制成，用于制造轴承套圈和滚动元件。对于高冲击载荷和交变弯曲应力的江苏nsk轴承，采用渗碳钢。
jiangsu nsk bearings are usually made of low alloy and high purity hardened chrome steel for making bearing rings and rolling elements. for jiangsu bearing nsk with high impact load and alternating bending stress, carburizing steel is used.
近年来，由于轴承钢的质量不断提高（当然价格也在上涨），江苏nsk轴承大大提高了轴承的承载能力。研究结果和实践经验表明，在润滑性好、环境清洁、载荷小的条件下，现行标准滚动轴承钢可达到无限疲劳强度。滚动轴承套圈和滚子的江苏nsk轴承热处理工艺保证轴承小于150度，尺寸稳定。对于较高的工作温度，需要特殊的热处理方法。轴承钢在腐蚀环境中必须具有腐蚀性。不锈钢标准轴承是前缀s和后缀w203b代码。
in recent years, due to the continuous improvement of the quality of bearing steel (of course, the price is rising), jiangsu nsk bearing has greatly increased the bearing capacity of bearing. the research results and practical experience show that under the condition of good lubricity, clean environment and small load, the current standard rolling bearing steel can reach infinite fatigue strength. the nsk bearing heat treatment process of rolling bearing rings and rollers ensures that the bearing is less than 150 degrees and the size is stable. for high working temperature, special heat treatment methods are needed. bearing steel must be corrosive in corrosive environment. stainless steel standard bearings are prefix s and suffix w203b code.
轴承和整个淬火轴承钢轴承具有相同的尺寸和承载能力。为了保持其耐腐蚀性，在安装和运行过程中不能损坏表面。江苏nsk轴承生产氮化硅球用于陶瓷主轴轴承。
the bearing and the whole quenching bearing steel bearing have the same size and bearing capacity. in order to maintain its corrosion resistance, the surface can not be damaged during installation and operation. jiangsu nsk bearing produces silicon nitride balls for ceramic spindle bearings.
陶瓷球比钢球轻得多，离心力和摩擦力明显小于钢球。轴承在润滑状态下仍能高速运转，使用寿命长，工作温度低。
the ceramic ball is much lighter than the steel ball, and the centrifugal force and friction force are obviously smaller than that of the steel ball. bearing can still run at high speed under lubrication condition, with long service life and low working temperature.
