During precision grinding of imported bearings, due to the extremely high surface finish requirements, grinding marks on the working surface are often visible to the naked eye. The main types of surface grinding marks are as follows. The primary cause of intersecting spiral marks on the surface is the poor straightness of the grinding wheel’s generatrix, resulting in unevenness. During grinding,...
First, accurately measure the dimensions at each defective area (asymmetrical type) on the part, calculate the minimum grinding allowance (M) required to achieve the finished dimensional tolerance, and then apply a centre offset during grinding...
When using SKF bearings, if you notice that the temperature is abnormally high, you should immediately stop the equipment, identify the cause, and address the issue in accordance with the solutions provided above. However, as the causes of bearing overheating may vary...
After undergoing complex flow patterns during the initial stage, the grease inside rolling bearings settles into a stable distribution. Ultimately, the minimal amount of grease remaining in a fluid state at the friction points performs the primary lubricating function, whilst the grease retained within the outer ring remains stationary and does not directly participate in lubrication. However...
When cleaning large quantities of imported bearings, first pour hot engine oil at a temperature of 90–100 °C over them to melt the sealing grease. At the same time, use a seamless, lint-free tool to scrape out all the old grease. Continue pouring hot oil over them for a few minutes...
