通常，軸由徑向和軸向兩個軸承支承。一側的軸承稱為固定端軸承。它同時承受徑向和軸向載荷，作為固定軸與軸承座之間的相對軸向位移。另一邊叫做自.由端。它只承受徑向載荷，可以相對軸向移動。

Usually, the shaft is supported by radial and axial bearings. Bearings on one side are called fixed end bearings. It bears both radial and axial loads and acts as the relative axial displacement between the fixed shaft and the bearing seat. The other side is called self-end. It only bears radial loads and can move relatively axially.

固定端淮安INA軸承bi須與軸和軸承箱同時固定。zui適合的軸承是能承受復雜載荷的徑向軸承，如深溝球軸承、調心滾子軸承、雙列或對角接觸球軸承或圓錐滾子軸承。徑向軸承的組合在簡單的徑向載荷下，如圓柱滾子軸承內圈和外圈有ribless，深溝球軸承或四點接觸球軸承或雙向推力軸承，也可以作為固定端軸承使用。此時，Di二軸承提供雙向軸向定位，但bi須與軸承箱安裝在一定的徑向間隔。當自.由端軸承的長度因熱膨脹而改變時，軸承內不會發生擠壓。軸向位移可能發生在軸承內部，以及軸承環和淮安INA軸承座。

The fixed end of Huaian INA bearing Bi shall be fixed simultaneously with the shaft and bearing box. Zui is suitable for bearings that can withstand complex loads, such as deep groove ball bearings, self-aligning roller bearings, double row or diagonal contact ball bearings or tapered roller bearings. The combination of radial bearings under simple radial loads, such as ribless inner and outer rings of cylindrical roller bearings, deep groove ball bearings or four-point contact ball bearings or bi-directional thrust bearings, can also be used as fixed-end bearings. At this time, Di 2 bearings provide bidirectional axial positioning, but Bi must be installed at a certain radial interval with the bearing box. When the length of self-end bearing is changed by thermal expansion, no extrusion will occur in the bearing. Axial displacement may occur inside the bearing, as well as the bearing ring and Huaian INA bearing seat.

“十字定位”是指軸承的配置，每個軸承都位于一個方向和相反的方向。這種組合主要用于短軸。所有徑向軸承，包括深溝和角接觸球軸承、圓錐滾子軸承和NJ圓柱滾子軸承，都適合承受至少一個方向的軸向載荷。在某些情況下，當使用角接觸球軸承或圓錐滾子軸承時，bi須施加預緊力。

"Cross positioning" refers to the configuration of bearings, each bearing is located in one direction and the opposite direction. This combination is mainly used for short axes. All radial bearings, including deep groove and angular contact ball bearings, tapered roller bearings and NJ cylindrical roller bearings, are suitable for bearing at least one direction of axial load. In some cases, when angular contact ball bearings or tapered roller bearings are used, Bi is required to exert preload.

在軸承選型階段，需要考慮許多因素(如載荷、硬度、工作環境等)。一個好的軸承設計首先會使軸承達到它的zui大壽命。

In the stage of bearing selection, many factors (such as load, hardness, working environment, etc.) need to be considered. A good bearing design will first make the bearing reach its Zui life.

2.正確儲存，淮安INA軸承應在安裝前按原包裝保存。它需要保持在一個干凈，潮濕和相對恒定的溫度環境。滾動軸承應遠離灰塵、水和腐蝕性化學品。振動和振動會對軸承的機械性能造成永.久性的破壞，因此在加工和儲存過程中應避免振動。一般來說，軸承應保持水平。一些較重的軸承在長期垂直放置后會因自身重量而變形。此外，潤滑(或密封)軸承需要特別小心，因為油脂的密度在長期儲存后會發生變化。軸承首.次使用時，會產生一定程度的旋轉噪聲。因此，這種軸承的保質期應根據先進先出原則進行控制。

2. Proper storage, Huaian INA bearings should be stored in the original packaging before installation. It needs to be kept in a clean, humid and relatively constant temperature environment. Rolling bearings should be kept away from dust, water and corrosive chemicals. Vibration and vibration will cause permanent damage to the mechanical properties of bearings, so vibration should be avoided in the process of processing and storage. Generally speaking, bearings should be kept level. Some heavier bearings will be deformed by their own weight after long-term vertical placement. In addition, lubricated (or sealed) bearings require special care because the density of grease changes after long-term storage. When the bearing head is used for a second time, it will produce a certain degree of rotational noise. Therefore, the shelf life of this kind of bearing should be controlled according to the first-in-first-out principle.
