  • What are the basic forms of INA bearing failure

      1. adhesive and abrasive wear  The INA bearings surface is one of the most common failure mode. Bearing sliding friction between getting the surface of metal loss known as sliding friction losses. Continued wear will make the part size and shape changes in bearing clearance increases work surface deterioration, thus losing running accuracy, bearing is not working properly. Sliding wear forms can be divided into abrasive wear abrasion, adhesion, [...]

  • INA motor bearing abnormal sound analysis and solution

  • INA precision bearing assembly points

    With the rapid development of numerical control technology, composite, high-speed, intelligent, precision, environmental protection has become the main trend of today's machine tool industry technology development. Wherein the high-speed machining can effectively improve the machining efficiency and to shorten the processing cycle of the workpiece, which requires the machine tool spindle and its associated components to adapt to the requirements [...]

  • How to check the INA bearing running condition

    How to check the working condition of INA bearings in operation, we're from the vibration of the bearing, scrolling, and temperature of the three talk about:First, check the INA bearing vibration at workIndentation cracks, wear, corrosion, spalling, are reflected in the INA bearing vibration measurement, bearing vibration of bearing damage is very sensitive, so by using a special bearing vibration Measurer (frequency Analyzer, etc) measures the s [...]

  • INA bearing four common possible causes of damage

    A, improper installation  1, the installation using brute force, tapping INA bearing directly on the bearing with a hammer hurt the largest is a major cause deformation.  2, the installation is not in place, install a biased or not loaded to INA bearings, resulting in bearing clearance is too small. Inner and outer rings are not in the same center of rotation, resulting in different hearts.  Recommendation: choose the proper bearing installation [...]

  • Teaches you how to choose eight standard INA bearing

    (1) size limitBearing installation space is usually limited. In most cases, the shaft diameter (or bearing diameter) is based on the mechanical design or other design constraints. INA bearing type and size selection is decided in accordance with the inner diameter of the bearing. Thus, main dimensions standard tables are prepared in accordance with international standards for dimension of inner diameter. Standard bearing dimensions and range in m [...]

  • INA bearings abnormal temperature increase was mainly attributable

    General, INA bearings will heat up in the beginning of the operation and, after a period of time, i.e. at a lower temperature (usually higher than room temperature 10 to 40 degrees) in the normal state. To the normal time, according to the bearing size, form, rotation speed, lubrication method, INA bearings around the exothermic conditions change, takes roughly 20 minutes to several hours.Bearing temperature does not reach the normal and abnormal [...]

  • Of INA bearings raw characteristics of the role of experimental analysis

  • Install the INA needle roller bearing note

    Bearing clearance is in the case of one ring fixed, another along the radial or axial rings made by the maximum amount of flow, clearance is divided into radial clearance and axial clearance in two ways. Move needle bearing Assembly, clearance must not be too large or too small. Clearance is too large, causing at the same time the move of the reduction in the number of loading and increased the load of a single move, thereby reducing the INA bear [...]
