Bearing accuracy research High precision is a typical feature of high-end machine tool bearings. The relevant theoretical research on bearing accuracy includes: Method, the analysis of the influence of parts manufacturing errors, lubrication, etc. on accuracy, the formation mechanism of bearing non-reproducible accuracy, and the influence of working conditions on accuracy. Bearing damage and failure mechanism Due to the more complex structure and harsher working conditions, the mutual coupling effect of various factors is more significant, so high-end bearings The damage and failure mechanisms... read more
The vibration (acceleration) of micro motor bearings is divided into four levels: Z1, Z2, Z3, and Z4; the unit of measurement is db; the vibration (speed) of bearings is divided into four levels: V1, V2, V3, and V4. The ZV1 level is suitable for bearing manufacturers to test the vibration of microminiature deep groove ball groove ball bearings in the standard scope; ZV2 level is suitable for bearing product inspection with general regulations on bearing vibration; ZV3 level is suitable for motors and other motor bearings that are relatively specified; ZV4 level is suitable when there are stric... read more
Compared with other types of bearings of the same size, deep groove ball bearings have a low friction coefficient, high limit speed, and high accuracy. They are the preferred bearing type when users select the type. Deep groove ball bearings are simple in structure and easy to use. They are the largest production batch and the most widely used bearings. Deep groove ball bearings are mainly used to bear radial loads, and can also bear certain axial loads. When the radial clearance of the bearing increases, it has the properties of angular contact ball bearings and can withstand axial loads that... read more
The current domestic application of 608 bearings is already very extensive, but the application industry is different, and the requirements are more and more. The production plant has to research and develop various materials again and again, and the properties of various materials are different to meet different needs. The demand of the industry, Jiashi Bearing has accumulated for many years, and has produced the following materials: Bearing steel material Bearing steel domestic 608 bearings are suitable for high speed or even high speed operation, and are very durable and do not require freq... read more
From the angle of use, to ensure that the bearing can work reliably, pay attention to the following points: 1. Improve the quality of lubrication, control the pressure, temperature and flow of engine oil, and strengthen the filtration of engine oil. 2. Use fuel and lubricating oil that meet the requirements. 3. Control the temperature state of the diesel generator set, and work under the condition of supercooling and overheating is unfavorable. In cold weather, the diesel engine should be preheated before starting, and the crankshaft should be turned by hand to allow the engine oil to enter th... read more
Whether the bearings are installed correctly affects accuracy, life, and performance. Therefore, the design and assembly department should fully study the bearing installation. Hope to install according to the operation standard. The work standard items are usually as follows: (1) Cleaning bearings and bearing related parts (2) Check the dimensions and finishing of related parts (3) Installation (4) Inspection after installing the bearing (5) Supply lubricant It is hoped that the bearing packaging will be opened just before installation. General grease is lubricated and filled with grease dire... read more
