YRT Rotary Table Bearings
YRT rotary table bearings belong to an ultra-precision grade bearing, so the bearing raceway needs to be super-finished to meet the high requirements of customers. YRT rotary table bearings are also a kind of high-precision bearings that are commonly used. It is a professional bearing specially designed for turntables. Therefore, in many high-precision fields, such as medical equipment, CNC machine tools, and even high-precision instruments such as radar, it has its application.
YRT rotary table bearings are composed of a centripetal race, a centripetal shaft ring, a thrust washer, two needle roller cage assemblies, and a centripetal cylindrical roller. Such bearings have high axial and radial load carrying capacity. The tilting stiffness is very high, and the bearings are also highly accurate, mostly used in rotary table, chuck and other bearing configurations. Because of the high precision, the YRT turntable bearing is also very demanding with the matching equipment parts.
Nowadays, the overall quality of high-precision processing equipment and industrial labor is getting smaller and smaller. YRT rotary table bearings are generally preloaded with negative clearance, so that they can withstand some bearing loads and avoid bearing stress. Heavy relationships have an impact on the accuracy of bearing use. Therefore, after selecting a good bearing, it is necessary to adjust the clearance so that the ideal operation can be achieved.
