淮安SKF轴承精度由0提高到6，满足一般要求。但是，在表1所示的条件下，精度要求为5或更高。
The accuracy of Huaian SKF bearing is improved from 0 to 6, which meets the general requirements. However, under the conditi*** shown in Table 1, the accuracy requirement is 5 or higher.
虽然上述精度等级是基于ISO标准，但其名称根据***标准而有所不同。
Although the above accuracy levels are based on ISO standa***, their names vary according to national standa***.
列出了适用于各种轴承类型的精度等级和***标准的比较。
Comparis*** of Accuracy grades and national standa*** applicable to various bearing types are listed.
标准进口轴承有各种尺寸和形式。在机械装置的设计中，标准轴承是手选。无论轴承是否容易购买，我们都会在这里保留一个。目录中有一些轴承类型，但中国打卤没有非标准轴承。有时***需要很长的时间，所以在选择淮安SKF轴承时，应考虑时间成本和时间成本。临时重置成本）
Standard imported bearings h***e various sizes and forms. In the design of mechanical devices, standard bearings are optional. Whether bearings are easy to buy or not, we will keep one here. There are some bearing types in the catalogue, but there are no non-standard bearings in China. Sometimes futures take a long time, so when choosing Huaian SKF bearings, time cost and time cost should be c***idered. Temporary replacement cost)
此外，在某些情况下，轴承预加载以增加刚性。该程序通常用于深沟球轴承、向心推力球轴承和圆锥滚子轴承内外环的偏差、轴的弯曲、轴或轴承箱的公差变化和配合误差，导致内外环偏心。轴承嫁格应防止偏心角过大。自动调心球轴承，自动调心滚子轴承或自动调心轴承座是更好的选择。语因频率和扭矩，滚动轴承是根据高精度标准制造的，因此声音和扭矩非常小。深沟球淮安SKF轴承和圆柱滚子轴承适用于低噪音和低扭矩应用。
In addition, in some cases, bearings are preloaded to increase rigidity. This program is usually used for deviation of inner and outer rings of deep groove ball bearings, centripetal thrust ball bearings and tapered roller bearings, bending of axles, tolerance variation of axles or bearing boxes, and matching errors, resulting in eccentricity of inner and outer rings. Bearing lattice should be prevented from too large eccentricity angle. Auto-aligning ball bearings, auto-aligning roller bearings or auto-aligning bearing seat are better choices. Because of frequency and torque, rolling bearings are manufactured according to high precision standa***, so the sound and torque are very ***all. Deep groove ball Huaian SKF bearings and cylindrical roller bearings are suitable for low noise and low torque applicati***.
轴承载荷，施加在轴承上的载荷，其性质、尺寸和方向是可变的。通常，额定基本负载显示在尺寸表上。但轴向载荷和径向载荷也是轴承选择的重要因素。当滚珠轴承和滚针轴承的尺寸相同时，滚针轴承通常具有较高的承载能力，承受较大的振动和冲击载荷。
Bearing load, the load applied on the bearing, its nature, size and direction are variable. Normally, the rated base load is displayed on the size table. But the axial load and radial load are also important factors in bearing selection. When the dimensi*** of ball bearings and needle bearings are the same, needle bearings usually h***e higher load-carrying capacity and bear larger vibration and impact loads.
允许转速由轴承类型、尺寸、精度、保持架类型、负荷、润滑方式和冷雀方式决定。标准精秘轴承在油润滑和油脂润滑下的允许转速见淮安SKF轴承表。深沟球轴承、调心球轴承和圆柱滚子轴承一般适用于高速运转。
The allowable speed is determined by bearing type, size, accuracy, cage type, load, lubrication mode and cold sparrow mode. The allowable speed of standard precision bearing under oil and grease lubrication can be seen in Huaian SKF bearing table. Deep groove ball bearings, self-aligning ball bearings and cylindrical roller bearings are generally suitable for high-speed operation.
轴承尺寸精度和旋转精度基于ISO和JIS标准。对于需要高精度和高速运行的机械，建议使用5级或更高精度的轴承。深沟球轴承、向心推力球轴承或圆柱滚子轴承适用于高精度机械。刚度，当滚动体与轴承滚道接触面受到压缩时，会产生弹性变形。有些机器需要***小化弹性变形。滚动淮安SKF轴承的弹性变形小于滚珠轴承。
Bearing dimension accuracy and rotation accuracy are based on ISO and JIS standa***. For machinery requiring high precision and high speed operation, it is recommended to use bearings of grade 5 or higher accuracy. Deep groove ball bearings, centripetal thrust ball bearings or cylindrical roller bearings are suitable for high precision machinery. Stiffness, when the contact surface between rolling element and bearing raceway is compressed, elastic deformation will occur. Some machines require *** to minimize elastic deformation. The elastic deformation of rolling Huaian SKF bearing is less than that of ball bearing.
