The YRT type consists of a centripetal race, a centripetal collar, a thrust washer, two needle retainers and a cylindrical roller. It is characterized by its high axial and radial load. The YRT bearing requirements for the working environment are also between 30 ° C and 120 ° C. The temperature generated during operation depends to a large extent on the conditions of the surrounding environment, so YRt also has its own limit speed.
YRt bearings are also fitted with seals, lubricated with grease and lubricated by the outer ring and L-ring. Because YRT is used in many fields, it also directly promotes the development of the mechanical equipment industry, which accelerates the development of high-speed, precision and intelligent machine tools.
