南京INA轴承由六个基本部件组成：外圈、内圈、滚子、保持架、密封件和润滑剂。轴承的主要作用是支撑机体的机械转动，减少运动过程中的摩擦系数。
Nanjing INA bearing c***ists of six basic components: outer ring, inner ring, roller, cage, seal and lubricant. The main function of the bearing is to support the mechanical rotation of the body and reduce the friction coefficient during the movement.
其南京INA轴承旋转精度。简而言之，只要外圈、内圈和滚动元件都可以定义为滚动轴承。根据滚动体的形状，滚动轴承可分为滚珠轴承和滚子轴承两大类。其次，简要介绍了上海轴承常用的轴承。惰轮的分类特征如下：
Its Nanjing INA bearing rotation accuracy. In short, as long as the outer ring, inner ring and rolling element can be defined as rolling bearings. According to the shape of rolling body, rolling bearings can be divided into two categories: ball bearings and roller bearings. Secondly, the bearings commonly used in Shanghai bearings are briefly introduced. The classification characteristics of idlers are as follows:
南京INA轴承圆柱滚子和滚子主要用于圆柱滚子轴承，也可直接用于机械滚子组件。滚筒的尺寸已被标准化，可用于商业辊的设计和用户选择。
Nanjing INA bearing cylindrical roller and roller are mainly used for cylindrical roller bearings, but also can be used directly for mechanical roller components. The size of the drum has been standardized, which can be used for the design and user selection of commercial rollers.
长圆柱滚子、滚子轴直径和无二轴直径，主要是长圆柱滚子轴承滚子组件也可直接用于机械。
Long cylindrical roller, roller shaft diameter and no two-axis diameter, mainly long cylindrical roller bearing roller assembly can also be directly used in machinery.
滚子主要用于滚针南京INA轴承、滚针轴承、万向联轴器滚针轴承和推力滚针轴承，滚针总成也可直接用于机械。根据设计要求，分批启动滚轮。根据针两端的形状，轴承的形状是锥头、平头和圆头。
Rollers are mainly used for needle roller bearing Nanjing INA, needle roller bearing, universal coupling needle roller bearing and thrust needle roller bearing, needle roller assembly can also be directly used in machinery. According to the design requirements, start the rollers in batches. According to the shape of the two ends of the needle, the shape of the bearing is cone head, flat head and round head.
圆锥滚子、滚子锥度和锥度角一般分为度、不足或过大，大部分为度。滚子的长度通常小于滚子端的直径。圆锥滚子南京INA轴承和大圆锥角滚子主要用于推力圆锥滚子轴承。
Tapered roller, roller taper and taper angle are generally divided into degrees, insufficient or too large, most of them are degrees. The length of the roller is usually less than the diameter of the roller end. Tapered roller Nanjing INA bearings and large conical angle rollers are mainly used for thrust tapered roller bearings.
滚子轴承具有自动调节心脏性能并能承受重载。球面滚子对称，不对称，底部不对称，形状对称，两端直。对称球面滚子的性能与夹具的形状不一致。这种滚子南京INA轴承和推力滚子轴承被使用。
Roller bearings h***e automatic regulation of heart performance and can withstand he***y loads. Spherical roller is symmetrical, asymmetrical, asymmetrical at the bottom, symmetrical in shape and straight at both ends. The performance of symmetrical spherical roller is not c***istent with the shape of fixture. This roller Nanjing INA bearing and thrust roller bearing are used.
螺旋辊是一种特殊的截面辊系，由空心辊制成，分为两部分。
The spiral roller is a special section roll system, made of hollow rollers and divided into two parts.
该轮不被广泛使用，主要用于冲击载荷的螺旋滚子轴承。一个轮毂孔、一个在滚子中心有通孔的毂孔和一个固定在柱上的孔笼。滚筒为圆柱形、球面、圆锥形，主要用于超大型进口轴承。
This wheel is not widely used and is mainly used for spiral roller bearings with impact load. A hub hole, a hub hole with a through hole in the center of the roller, and a hole cage fixed on the column. The drum is cylindrical, spherical and conical, and is mainly used for super large imported bearings.
