在SKF轴承安装中，各工程师关心的就是如何正确操作了，如果操作不当很可能会造成SKF轴承的损伤。如在高速条件下运转，而且工作温度较高，应特别注意旋转套圈的配合不可过松，以防止出现偏心振动，以及固定套圈的配合不可出现间隙，以防止套圈在负荷下变形并激发振动。
In the installation of SKF bearings, the engineers are most concerned about how to operate correctly, if not properly, it is likely to cause damage to SKF bearings. If the ring runs at high speed and the working temperature is high, special attention should be paid to the matching of the rotating ring, so as to prevent eccentric vibration, and the matching of the fixed ring can not appear clearance, so as to prevent the ring from deformation and vibration under load.
旋转套圈灼过盈量在可能范围内也宜取得较小。只要切实保证工作温度下的热膨胀影响，以及高转速下的离心力影响，才不致造成紧配合表面的蠕动或滑动。固定套圈根据工作载荷大小和SKF轴承尺寸，选取极小的间隙配合或过盈配合，过松或过紧都不利于保持原来精确的形状。
It is also possible to achieve a smaller amount of interference within the range of possible rotation rings. As long as the thermal expansion effect at working temperature and the centrifugal force effect at the highest rotating speed are ensured, the creeping or sliding of the tightly matched surface will not be caused. Fixed ring according to the size of the working load and SKF bearing size, select a minimum clearance fit or interference fit, too loose or too tight is not conducive to maintaining the original accurate shape.
既要精确计算旋转套圈配合的过盈量，也要精确计算固定套圈的合适配合量。
It is necessary to accurately calculate not only the interference of rotating ring, but also the fit of fixed ring.
轴与座孔的圆度以及挡肩的垂直度要按照SKF轴承的相应精度来要求。
The roundness of the shaft and the hole and the perpendicularity of the shoulder should be in accordance with the corresponding accuracy of the SKF bearing.
保持架组装精度靠专用组装胎具保证，完全可以保证SKF轴承的组装精度要求。
The assembling precision of cage is guaranteed by special assembling fixture, which can completely guarantee the assembling precision requirement of SKF bearing.
对固定圈采取小过盈配合的条件是相配表面双方都有很高形状精度和较小的粗糙度，否则造成安装困难而拆卸更难，此外，还需要考虑主轴热伸长的影响。
The condition of small interference fit for the fixed ring is that both sides of the matching surface have high shape precision and small roughness, otherwise it will be difficult to install and disassemble. In addition, the influence of spindle thermal elongation should be considered.
摆动载荷和不定载荷在配合上应与旋转载荷同等看待，过松的配合会导致配合面损坏。
The swing load and indeterminate load should be treated as the rotating load on the matching. The loose matching will lead to the damage of the matching surface.
相对于载荷方向旋转的套圈与轴或座孔，应选择过渡配合或过盈配合。过盈大小以SKF轴承在载荷下工作时，其套圈在轴上或座孔内的配合表面上不产生“蠕动”现象为原则。而在载荷很轻，或在重载荷作用下套圈偶有低速转动时，可选用过渡配合，此时轴表面应有较高的硬度和较小的表面粗糙度。
Transitional fit or interference fit should be chosen for the ring and shaft or seat hole relative to the load direction. The interference size is based on the principle that when SKF bearing works under load, the ring does not creep on the mating surface of shaft or seat hole. When the load is very light, or when the ring is occasionally rotated at low speed under heavy load, the transition fit can be chosen. At this time, the shaft surface should have higher hardness and smaller surface roughness.
对于重载荷场合，通常应比在轻载荷和正常载荷场合的配合为紧。载荷愈重，其配合过盈应愈大。
For heavy load occasions, it should be more compact than the light load and normal load occasions. The heavier the load is, the greater the interference should be.
使用成对双联角接触球轴承的主轴，多半载荷较轻，其配合过盈量如偏大，则其内部的轴向预紧量将显著偏大，造成不利影响。使用双列短圆柱滚子轴承的主轴以及圆锥滚子轴承的主轴，其载荷相对较大，所以其配合过盈也相对较大。
Most of the spindles with paired angular contact ball bearings have light loads. If the fit interference is too large, the axial preload inside the spindles will be significantly larger, resulting in adverse effects. The spindle with double row short cylindrical roller bearings and the spindle with tapered roller bearings have relatively large load, so their fit interference is relatively large.
有时载荷的方向和大小无法确切地判定，例如在高速旋转机械中，除所承受转子重量为方向固定的载荷而外，还有不平衡质量所引起的旋转载荷，如果这种旋转载荷比固定载荷大得多，则其合成载荷仍为旋转载荷；而如果旋转载荷比固定载荷小得多，则合成载荷为摆动载荷。不论旋转载荷还是摆动载荷， SKF轴承其大小和方向都在不断变化。而在可变工作状态下，有的套圈所受载荷可能时而是旋转载荷，时而是固定载荷，又时而是摆动载荷。这种载荷称为不定载荷。
Sometimes the direction and magnitude of the load can not be determined precisely, for example, in high-speed rotating machinery, there are rotational loads caused by unbalanced mass besides the loads on which the rotor weight is fixed in the direction. If the rotational loads are much larger than the fixed loads, the composite loads are still rotational loads; and if the rotational loads are still rotational loads. The load is much smaller than the fixed load, and the composite load is the swing load. Regardless of rotary load or swing load, the size and direction of SKF bearings are constantly changing. In the case of variable working conditions, some rings may be subjected to rotating loads, sometimes fixed loads, and sometimes swing loads. This load is called an indefinite load.
