Excessive noise present on the surface bearing bearing failure

Stainless steel slewing bearing at work allows slight noise, if the noise is too large or unusual noise or crash, it indicates that the bearing has failed.
Bearing noise is more complex reasons, please check the following causes:
1) is the bearing inner and outer rings with surface wear. Since this kind of wear and tear in, destroyed the bearings and housings, bearings and shaft with the relationship, leading to a deviation from the correct position axis, the axis moves at high speed generate abnormal sound. When the bearing fatigue, the surface metal flake, but also make the bearing radial clearance increased abnormal sound.
2) lack of bearing lubrication, the formation of dry friction, and bearing broken, etc. will have an unusual sound.
3) After Songkuang bearing wear, damage loose retainer, bearing damage will produce abnormal noise. Bearing Removal Inspection, can be judged according to bearing damage and damage to the cause of bearing failure.However, cross roller bearings in other respects, however, has INA rotary table bearings insurmountable advantage, first of all, in the structure of the cross roller bearings and INA rotary table bearings, cross roller bearing structure is relatively simple and more, through a row in a single raceway intersecting cylindrical rolling elements are arranged, it can get quite large axial, radial bearing capacity and overturning moment, while INA rotary table bearings must pass three rows of three-row cylindrical rolling element raceway in order to achieve the same effect, which in the production and processing to bring a lot of inconvenience, relative to the cross roller bearings, single row raceway, INA rotary table bearings production and processing greatly increased the complexity, the difficulty also increased significantly, which is production and processing equipment and production staff made a very high quality requirements, it is known that the current domestic high-precision processing equipment and the overall quality of industrial workers compared with foreign countries there are still a large gap, which is why the domestic production of INA rotary table bearings has never stability, the main reason is difficult to meet user requirements, this will inevitably cause the high reject rate INA rotary table bearings, substantial increase in production costs, the production cycle is too long and difficult to mass production.
