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,...
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...
In order to maintain the original performance of bearings for as long as possible, maintenance and repairs must be carried out to prevent accidents, ensure operational reliability, and improve production efficiency and rationality. Maintenance procedures are closely aligned with the actual...
Common quality defects in bearing components following heat treatment include: overheating or underheating of the quenched microstructure, quenching cracks, insufficient hardness, heat treatment distortion, surface decarburisation and soft spots...
