通常，轴由两个轴承在径向和轴向上支撑。此时，南京SKF轴承的一侧称为固定侧轴承，而另一侧称为不固定侧。固定侧轴承能够承受径向和轴向载荷，并作为固定轴和轴承箱之间的相对轴向位移。
Normally, the shaft is supported by two bearings in radial direction and axial direction. At this point, one side of the SKF bearing in Nanjing is called the fixed side bearing while the other side is called the unfixed side. The fixed side bearing can bear radial and axial loads and act as the relative axial displacement between the fixed shaft and the bearing box.
不固定侧只能承受南京SKF轴承径向载荷，轴向运动可以相对移动。因此，可以解决由于温度变化和轴承间距偏差引起的轴膨胀问题。今天，给大家介绍一下，在选择轴承类型时，要掌握轴承的条件选择！
The unfixed side can only bear the radial load of Nanjing SKF bearing, and the axial movement can move relatively. Therefore, the shaft expansion problem caused by temperature change and bearing spacing deviation can be solved. Today, I would like to introduce to you that when choosing the bearing type, we should master the choice of the bearing condition.
安装南京SKF轴承空间是指可容纳在轴承安装空间中的轴承类型。因为轴系的设计中点在于轴的刚度和强度，所以通常首先确定轴的直径（即轴承直径）。
The installation of Nanjing SKF bearing space is the type of bearing that can be housed in the bearing mounting space. Because the design midpoint of the shafting is the stiffness and strength of the shaft, the diameter of the shaft (that is, the bearing diameter) is usually determined first.
速度是指能够适应机械速度的轴承类型。轴承是用来生产轴承的。南京SKF轴承在***轴承行业处于不可或缺的地位。标准产品有20000多个轴承。轴承极限转速由轴承类型、保持架类型、轴承尺寸、载荷条件、精度水平、润滑方式等因素决定，因此在选择时务须考虑这些因素。
Speed refers to the types of bearings that can be adapted to mechanical speed. Bearings are used to produce bearings. Nanjing SKF bearing is an indispensable position in the global bearing industry. The standard product has more than 20000 bearings. Bearing limit speed is determined by bearing type, cage type, bearing size, load conditi***, accuracy level, lubrication mode and other factors, so these factors should be c***idered in the selection.
轴承载荷变化很大，如载荷大小、径向载荷、轴向载荷是单向或双向的、振动或冲击程度。凭借我们在南京SKF轴承领域的丰富经验，我们具备开发、制造和应用各种***工程产品的必要知识和专长。小型轴承，如微型轴承，只有0.003克，大轴承高达30~40t。在考虑这些因素后，选择尽可能合适的轴承类型。
Bearing load varies greatly, such as load size, radial load, axial load is one-way or two-way, vibration or impact degree. With our rich experience in the field of SKF bearings in Nanjing, we h***e the necessary knowledge and expertise to develop, manufacture and apply various advanced engineering products. ***all bearings, such as miniature bearings, are only 0.003 grams, with large bearings up to 30~40t. After c***idering these factors, choose the most suitable bearing type.
包括载荷方向和载荷类型、速度、***或不***、同轴度要求、平滑方法、安装维护环境、环境温度等条件，选择轴承的基本类型、公差等级和间隙；模拟速度。
Including load direction and load type, speed, positioning or not positioning, coaxiality requirements, ***oothing method, installation and maintenance environment, environmental temperature and other conditi***, select the basic type of bearing, tolerance level and clearance; simulation speed.
