经常使用SKF轴承的朋友都知道，SKF轴承安装的好坏与否，将影响到SKF轴承的精度、寿命和性能。因此，请充分研究SKF轴承的安装，即请按照包含如下项目在内的步骤进行SKF轴承安装。
Friends who often use SKF bearings know that the installation of SKF bearings will affect the accuracy, life and performance of SKF bearings. Therefore, please fully study the installation of SKF bearings, that is, please follow the steps included in the following items SKF bearing installation.
（一）、清洗SKF轴承及相关零件（(1) cleaning SKF bearings and related parts.）
对已经脂润滑的SKF轴承及双侧具油封或防尘盖，密封圈SKF轴承安装前无需清洗。
For greasy lubricated SKF bearings and bilateral oil seal or dust cover, seal ring SKF bearings need not be cleaned before installation.
（二）、检查相关零件的尺寸及精加工情况（(two) check the dimensions and finishing of the relevant parts.）
（三）、安装方法（(three) installation method）
SKF轴承的安装应根据SKF轴承结构，尺寸大小和SKF轴承部件的配合性质而定，压力应直接加在紧配合得套圈端面上，不得通过滚动体传递压力，SKF轴承安装一般采用如下方法：
SKF bearings should be installed according to the SKF bearing structure, size and the matching nature of SKF bearing components, the pressure should be directly added to the tightly matched end face of the ring, not through the rolling body to transmit pressure, SKF bearing installation generally adopts the following methods:
A. 压入配合（press fit）
SKF轴承内圈与轴使紧配合，外圈与SKF轴承座孔是较松配合时，可用压力机将SKF轴承先压装在轴上，然后将轴连同SKF轴承一起装入SKF轴承座孔内，压装时在SKF轴承内圈端面上，垫一软金属材料做的装配套管（铜或软钢），装配套管的内径应比轴颈直径略大，外径直径应比SKF轴承内圈挡边略小，以免压在保持架上。SKF轴承外圈与SKF轴承座孔紧配合，内圈与轴为较松配合时，可将SKF轴承先压入SKF轴承座孔内，这时装配套管的外径应略小于座孔的直径。如果SKF轴承套圈与轴及座孔都是紧配合时，安装室内圈和外圈要同时压入轴和座孔，装配套管的结构应能同时押紧SKF轴承内圈和外圈的端面。
SKF bearing inner ring and shaft to make tight fit, outer ring and SKF bearing seat hole is loose fit, can be used to press the SKF bearing on the shaft first, and then the shaft together with SKF bearing into SKF bearing seat hole, press installation in SKF bearing inner ring end face, pad a soft metal material made of assembly sleeve (copper or soft steel), assembly sleeve The inner diameter of the tube should be slightly larger than the Journal diameter, and the outer diameter should be slightly smaller than the SKF bearing inner ring flange to avoid pressure on the cage. SKF bearing outer ring and SKF bearing seat hole tight fit, the inner ring and shaft is loose fit, SKF bearing can be pressed into the SKF bearing seat hole first, this fashion supporting pipe should be slightly smaller than the diameter of the seat hole. If the SKF bearing rings are tightly matched with the shaft and seat holes, both the inner and outer rings of the SKF bearing should be pressed into the shaft and seat holes at the same time, and the sleeve structure should be able to tighten the ends of the inner and outer rings of the SKF bearing at the same time.
B.加热配合（ heating fit）
通过加热SKF轴承或SKF轴承座，利用热膨胀将紧配合转变为松配合的安装方法。是一种常用和省力的安装方法。此法适于过盈量较大的SKF轴承的安装，热装前把SKF轴承或可分离型SKF轴承的套圈放入油箱中均匀加热80-100℃，然后从油中取出尽快装到轴上，为防止冷却后内圈端面和轴肩贴合不紧，SKF轴承冷却后可以再进行轴向紧固。SKF轴承外圈与轻金属制的SKF轴承座紧配合时，采用加热SKF轴承座的热装方法，可以避免配合面受到擦伤。用油箱加热SKF轴承时，在距箱底一定距离处应有一网栅，或者用钩子吊着SKF轴承，SKF轴承不能放到箱底上，以防沉杂质进入SKF轴承内或不均匀的加热，油箱中必须有温度计，严格控制油温不得超过100℃，以防止发生回火效应，使套圈的硬度降低。
By heating SKF bearing or SKF bearing seat, the tight fit is transformed into loose fit by thermal expansion. It is a common and labor-saving installation method. This method is suitable for the installation of SKF bearings with large interference. The rings of SKF bearings or separable SKF bearings are heated in the tank at 80-100 C before hot-charging, and then removed from the oil and installed on the shaft as soon as possible. In order to prevent the end face of the inner ring and the shoulder from not tightly fitting after cooling, the SKF bearings can be axially fastened after cooling. When the outer ring of SKF bearing is tightly matched with the SKF bearing seat made of light metal, the hot-charging method of heating the SKF bearing seat can avoid scratching of the matching surface. When heating SKF bearings with oil tanks, there should be a grid at a certain distance from the bottom of the tank, or SKF bearings should be hoisted with hooks. SKF bearings can not be placed on the bottom of the tank to prevent sunken impurities from entering the SKF bearings or heating unevenly. Thermometers must be installed in the tank to strictly control the oil temperature not to exceed 100 degrees Celsius to prevent tempering effect. Reduce the hardness of rings.
C.圆锥孔SKF轴承的安装（Installation of conical hole SKF bearing）
圆锥孔轴承可以直接装在有锥度的轴颈上，或装载紧定套和退卸套的锥面上，其配合的松紧程度可用SKF轴承径向游隙减小量来衡量，因此，安装前应测量SKF轴承径向游隙，安装过程中应经常测量游隙以达到所需要的游隙减小量为止，安装时一般采用锁紧螺母安装，也可采用加热安装的方法。
Tapered bore bearings can be mounted directly on a tapered journal or on a tapered surface with a tightening sleeve and a retracting sleeve. The tightness of the fit can be measured by the radial clearance reduction of SKF bearings. Therefore, the radial clearance of SKF bearings should be measured before installation, and the clearance should be measured frequently during installation to achieve the required clearance reduction. Up to now, the installation of lock nut is usually installed, and heating installation can also be used.
D.推力SKF轴承的安装（Installation of thrust SKF bearings）
推力轴承的周全与轴的配合一般为过渡配合，座圈与SKF轴承座孔的配合一般为间隙配合，因此这种SKF轴承较易安装，双向推力SKF轴承的中轴泉应在轴上固定，以防止相对于轴转动。SKF轴承的安装方法，一般情况下是轴旋转的情况居多，因此内圈与轴的配合为过赢配合，SKF轴承外圈与SKF轴承室的配合为间隙配合。
The combination of thrust bearing and shaft is usually a transition fit, and the fit of seat ring and SKF bearing seat hole is usually a clearance fit. Therefore, the SKF bearing is easy to install, and the shaft spring of the two-way thrust SKF bearing should be fixed on the shaft to prevent rotation relative to the shaft. Installation method of SKF bearing is usually the case of shaft rotation, so the matching of inner ring and shaft is over-winning, and the matching of SKF bearing outer ring and SKF bearing chamber is clearance matching.
