skf轴承游隙，即指skf轴承在未装置于轴或轴承箱时，将其内圈或外圈的一方固定，然后便未被固定的一方做径向或轴向移动时的移动量。一般说来，skf轴承旋转时的持续时间长，中止缓慢，灵敏进口轴承性就好。反之，旋转时间短，中止突然，灵敏性就欠好。根据移动方向，可分为径向游隙和轴向游隙。
Skf bearing clearance refers to the amount of movement of a SKF Bearing when its inner ring or outer ring is fixed on one side of the bearing without being mounted on the shaft or bearing box, and then the unsettled side moves radially or axially. Generally speaking, SKF bearings rotate long duration, slow down, sensitive import bearing is good. On the contrary, the rotation time is short and the abrupt change is not good. According to the direction of movement, it can be divided into radial clearance and axial clearance.
skf轴承径向游隙的测量并不简单，进口轴承测量力使套圈和翻滚体本身及其触摸处发作弹性变形，变形量是构成测量差错的多要素，与测量力、触摸状况和翻滚体的方位都有关。
The measurement of radial clearance of SKF Bearing is not simple. The measuring force of the imported bearing causes elastic deformation of the ring and the roll body itself and its touch part. The deformation is a multi-element of the measurement error, which is related to the measuring force, the touch condition and the orientation of the roll body.
skf轴承旋转灵敏性一般在水平方位查看，通常将内圈固定，用手翻滚外圈，查看skf轴承旋转时是否有反常动静及阻滞现象。因skf轴承结构型式及尺寸不同，对其旋转灵敏性亦应有不同的要求。
The rotational sensitivity of SKF bearings is generally checked in the horizontal position. Usually, the inner ring is fixed and the outer ring is rolled by hand to check whether there is abnormal static and dynamic phenomena when the SKF bearings rotate. Because of the different structure and size of SKF Bearing, there should be different requirements for its rotational sensitivity.
比如单列向心球轴承、单列向心推力球轴承，因为翻滚体与套圈之间的触摸面积小，这些skf轴承旋转时就比较轻捷，而双列向心球面轴承和推力滚子轴承，因为翻滚体与滚道的触摸面积较大，而外圈的分量又较小，查看其旋转灵敏性时，虽加上一定负荷，但其轻捷水平仍不及单列向心球轴承。
For example, single-row centripetal ball bearings and single-row centripetal thrust ball bearings, because the contact area between the rollers and the rings is small, these SKF bearings rotate more easily, while double-row centripetal spherical bearings and thrust roller bearings, because the rollers and the raceway touch area is larger, and the outer ring component is smaller, check its rotation When sensitivity is added to a certain load, its lightweight level is still less than single row centripetal bearing.
skf进口轴承保养办法：（SKF maintenance measures for imported bearings:）
1、首先把skf进口轴承放入汽油中清洗，擦去残留在skf进口轴承上的油泥和尘埃，但凡有锈迹的skf进口轴承都用金砂纸悄悄擦洗磨光，直至用手摸无粗糙感为止。
1. First of all, the SKF imported bearings are washed in gasoline, and the remaining oil and dust on the SKF imported bearings are wiped off. However, any rusty SKF imported bearings are quietly scrubbed and polished with gold sandpaper until no rough feeling is felt by hand.
2、用干碎布将清洗后的skf进口轴承抹干，再放入防锈油中浸泡。此过程中，要将skf进口轴承完全地与防进口轴承锈油触摸，并不停翻滚skf进口轴承，这样才会使防锈油构成的油膜掩盖在skf进口轴承的外表，达到防锈的意图。
2, dry rags to dry the SKF imported bearings after cleaning, and then immerse them in antirust oil. In this process, the SKF imported bearings should be completely touched with the rust oil of the imported bearings, and the SKF imported bearings will not stop rolling. only in this way can the oil film formed by the rust oil be covered in the appearance of the SKF imported bearings to achieve the purpose of rust prevention.
3、接下来用锂基脂，黄油需均匀地涂在skf进口轴承的外表，包含内外圈、轮子、坚持架。并且是边抹边翻滚skf进口轴承，使黄油真正进入skf进口轴承内部，起到充分光滑作用。
3. Next, with lithium grease, butter should be evenly coated on the surface of SKF imported bearings, including inner and outer rings, wheels, holders. And the SKF import bearing is rolled while wiping, so that butter really into the SKF import bearing, play a full smooth role.
