并非所有的徐州NSK轴承都要求**小工作间隙，**须根据情况选择适当的间隙。根据国家标准4604-93，滚动轴承径向间隙分为5组：2组、0组、3组、4组和5组。间隙值从小到大不等，0组为标准间隙。基本径向间隙组适用于一般工况、常温和过盈配合；对于在高温、高速、低噪音、低摩擦等特殊工况下工作的轴承，应选用大径向间隙；对于精细主轴和机床用轴承，应选用大径向间隙。应选择间隙。应选择间隙。还应选择大的径向间隙。**一轴应选择较小的径向间隙，滚子徐州NSK轴承可保持较小的工作间隙。此外，在分离轴承中没有间隙。**后，进口轴承安装后的工作间隙小于安装前的工作间隙，因为轴承**须承受一定的载荷旋转、轴承配合和载荷引起的弹性变形。
Not all Xuzhou NSK bearings require ** small working clearance, ** appropriate clearance should be selected according to the situation. According to the national standard 4604-93, the radial clearance of rolling bearings is divided into five groups: 2 groups, 0 groups, 3 groups, 4 groups and 5 groups. The clearance values ranged from small to large, and 0 groups were standard clearances. Basic radial clearance group is suitable for general working conditions, normal temperature and interference fit; for bearings working under special working conditions such as high temperature, high speed, low noise and low friction, large radial clearance should be selected; for bearings used in fine spindles and machine tools, large radial clearance should be selected. Clearance should be selected. Clearance should be selected. Large radial clearance should also be selected. ** A smaller radial clearance should be selected for the first axis. The roller Xuzhou NSK bearing can maintain a smaller working clearance. In addition, there is no clearance in the separation bearing. After **, the working clearance of imported bearing after installation is less than that before installation, because bearing ** must bear certain load rotation, bearing coordination and elastic deformation caused by load.
根据轴承的结构和性能，可分为滑动轴承和滚动轴承。顾名思义，滑动轴承是一种接触面积大的平面轴承，其磨损程度相对较大，即摩擦系数较大。因此，滑动轴承需要特殊的材料，而抗摩擦是其**大的特点。滚动徐州NSK轴承和滑动轴承具有不同的特点。它把轴座和轴之间的滑动摩擦转化为滚动摩擦，减少损失。然后利用内外圈、滚动体、保持架的相互作用来完成工作。
According to the structure and performance of bearings, they can be divided into sliding bearings and rolling bearings. As the name implies, sliding bearing is a kind of plane bearing with large contact area, and its wear degree is relatively large, that is, the friction coefficient is larger. Therefore, sliding bearings need special materials, and anti-friction is its major feature. Rolling Xuzhou NSK bearings and sliding bearings have different characteristics. It transforms sliding friction between shaft seat and shaft into rolling friction and reduces losses. Then the work is completed by using the interaction of inner and outer rings, rolling bodies and cages.
无论是滚动轴承还是进口滑动轴承，虽然工作原理不同，但作用是一样的。它们都是为了减小机械动力传递过程中产生的机械载荷的摩擦系数，并支撑机械旋转体。
Whether rolling bearings or imported sliding bearings, although the working principle is different, but the role is the same. They are all designed to reduce the friction coefficient of the mechanical load generated in the process of mechanical power transmission and support the mechanical rotating body.
轴承是一种精细零件，广泛应用于徐州NSK轴承各个领域。根据结构或类型，可分为多种。**常见的摩擦特性分类是滚动轴承和滑动轴承，它们也有所不同。显然，滚动轴承的摩擦阻力小于滑动轴承，启动速度更快，效率更高。这是滚动轴承与滑动轴承相比**大的优点。但是，也有缺点，即尺寸越大，减震能力越弱，高速寿命越短，使用时间越长，会发出越大的异常声音。滚动轴承和滑动轴承的另一个本质区别是滚动徐州NSK轴承是表面接触，而滑动轴承是点接触。滚动轴承接触面大，结构简单，操作拆卸方便，润滑要求高。
Bearing is a fine part, which is widely used in various fields of Xuzhou NSK bearing. According to the structure or type, it can be divided into many kinds. ** The common classification of friction characteristics is rolling bearings and sliding bearings, which are also different. Obviously, the friction resistance of rolling bearings is less than that of sliding bearings, and the starting speed is faster and the efficiency is higher. This is the advantage of rolling bearings over sliding bearings. However, there are also shortcomings, that is, the larger the size, the weaker the shock absorption capacity, the shorter the high-speed life, and the longer the use time, the greater the abnormal sound will be emitted. Another essential difference between rolling bearings and sliding bearings is that rolling Xuzhou NSK bearings are surface contact while sliding bearings are point contact. The rolling bearing has large contact surface, simple structure, convenient operation and disassembly, and high lubrication requirements.
