产品简介：圆柱滚子轴承
描述
- 单列圆柱滚子轴承是径向轴承，其中最多的是 - 满装圆柱滚子轴承 - 可分离
它们的边界尺寸分别由DIN标准DIN标准和DIN 5412 / part 1标准化。
由于安装轴承的不同部件，即外圈和内圈的可能性，单独的安装变得更容易。
此外，该技术特征允许在两个环中使用压配合，这在发生振动或冲击载荷的应用中是有利的。
根据其设计，单列圆柱滚子轴承是理想的定位轴承，尽管变形设计变化也可以在一个或两个方向上处理高达一定量的推力。
在具有有限空间的轴承应用（即齿轮箱）的情况下，也可以使用单列圆柱滚子轴承而不使用它们各自的外圈或内圈，
即RN型和RNU型轴承

其主要尺寸由DIN5412 /第4部分标准化。
它们用作机床主轴的轴承布置中的定位轴承。
因此，这些轴承通常用于高精度公差等级，经常结合减少内部间隙。这些轴承还具有高径向载荷能力，并且对于高速应用是令人满意的，提供非常刚性和刚性的轴承装置。它们也通常用于锥形孔，即后缀k（即taper1：12）

Description
--Single row cylindrical roller bearings are radial bearings,of whom are the most designs - with the exception of full complement cylindrcal roller bearings - are separable
Their boundary dimensions are standardized by the DIN standards DIN standard plans and DIN 5412/part 1,respectively.
Due to the possibility of fitting the different components of the bearings,i.e the outer and the inner rings, individually the mounting becomes easier.
Furthermore,this technical feature allows for the use of press fits for both rings which is of advanta-ge in applications where vibrations or shock loads occur.
Depending on their design,single row cylindrical roller bearings are ideal non-locating bearings,although variouse design variations can also handle thrust forces up to an certain amount inone or both directions.
In the case of bearing applications having limi-ted space available (i.e gear boxes),single row cylindrical roller bearings can also be used without their respective outer or inner rings,
i.e.,RN-type and RNU-type bearings,respectively
--Series NN30&NNU49 double Row Cylindrical Roller Bearings are separable radial bearings.ings.ings.
Their main dimensions are standardized by DIN5412/part 4.
They are used as non-locating bearings in bearing arrangements of machine tool spindles.
Therefore, these bearings are normally used in high precision tolerance class, frequently in combination with reduce internal clearance. These bearings also feature high radial load capacity and are satisfactory for high speed applications, providing a very stiff and rigid bearing arrangement. They are also commonly used with tapered bores, namely suffix k, (i.e.taper1:12)
