双列泰州NSK轴承61828-Z圆柱滚子系列的内外在

通常双列圆柱滚子轴承可以在安装空间内受到限*制。在大多数情况下，轴直径（或轴承直径）是基于机械设计或其*他设计约束。因此，轴承类型和尺寸的选择取决于轴承的内径。因此，标准泰州NSK轴承的主要尺寸符合国际标准尺寸。

Usually double row cylindrical roller bearings can be restricted in the installation space. In most cases, the shaft diameter (or bearing diameter) is based on mechanical design or its * design c***traints. Therefore, the choice of bearing type and size depends on the inner diameter of the bearing. Therefore, the main dimensi*** of the standard Taizhou NSK bearing conform to the international standard size.

标准双列圆柱滚子轴承具有不同的尺寸和形状。标准轴承**好用于机械设计（无论轴承是否易于购买，我们暂时不讨论它们）。一些轴承确实存在于市场，但是一些非标准轴承在中国大*陆没有库存，有时***会非常好。长期以来，在选择轴承类型时，必*须考虑更换的时间和成本。应用于轴承的双列圆柱滚子泰州NSK轴承的载荷在性质、尺寸和方向上都是可变的。通常，额定基本负荷显示在尺寸表上。然而，轴向载荷和径向载荷也是选择合适的SKF轴承的重要因素。当滚珠轴承和滚针轴承的尺寸相同时，双列圆柱滚子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。

Standard double row cylindrical roller bearings h***e different sizes and shapes. Standard bearings are good for mechanical design (whether bearings are easy to buy or not, we will not discuss them for the time being). Some bearings do exist in the market, but some non-standard bearings are not in stock in mainland China, and sometimes futures will be very good. For a long time, when choosing bearing type, it is necessary to c***ider the time and cost of replacement. The load of Taizhou NSK bearings with double row cylindrical rollers is variable in nature, size and direction. Normally, the rated basic load is displayed on the size table. However, axial load and radial load are also important factors to select suitable SKF bearings. When the dimensi*** of ball bearings and needle bearings are the same, double row cylindrical roller bearings usually h***e higher load-carrying capacity and bear larger vibration and impact loads.

第*二，轴承转速。

* two, bearing speed.

根据双列圆柱滚子轴承的类型、尺寸、精度、保持架类型、载荷、润滑方式和冷*却方式确定允许转速。泰州NSK轴承表显示了标准精*密轴承在油润滑和油脂润滑下的允许速度。一般来说，深沟球轴承、自调心球轴承和圆柱滚子轴承适用于高速运转。

The allowable speed is determined according to the type, size, accuracy, cage type, load, lubrication mode and cooling mode of double row cylindrical roller bearings. The NSK bearing table in Taizhou shows the permitted speed of standard precision compact bearings under oil lubrication and grease lubrication. Generally speaking, deep groove ball bearings, self aligning ball bearings and cylindrical roller bearings are suitable for high-speed operation.

第三。轴承公差

Third. Bearings tolerance

双列圆柱滚子轴承的尺寸精度和旋转精度是根据ISO和JIS标准制定的。对于要求高精度和高速度的机械，推荐使用5个或更多的精*密泰州NSK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床。刚度，当轴承滚子和滚道接触面压力时，会产生弹性变形。一些机器需要**小化弹性变形。滚子轴承具有比球轴承更小的弹性形状。

The dimensional accuracy and rotation accuracy of double row cylindrical roller bearings are based on ISO and JIS standa***. For machinery requiring high accuracy and high speed, 5 or more fine and dense Taizhou NSK bearings are recommended. Deep groove ball bearings, centripetal thrust ball bearings or cylindrical roller bearings are suitable for high-precision machine tools. Stiffness, when bearing roller and raceway contact surface pressure, will produce elastic deformation. Some machines need ***all deformation and elastic deformation. Roller bearings h***e ***aller elastic shape than ball bearings.
