YRT rotary table bearings is a kind of outer ring rotating, inner ring support rotary mechanism, mainly divided into YRT type, YRTS type, YRTM type three series, this three series bearings have the same mounting dimensions, there are differences in the internal structure, the performance is similar. YRT series bearings have three rows of rollers, two rows of axial rollers to ensure stable axial load carrying capacity, a row of radial roller to ensure that bearings can withstand radial force and tilting moment effect. Can withstand radial force and tilting moment role, suitable for axial bearing rotary mechanism.YRT rotary table bearings are mainly used in CNC machine tool manufacturing industry, as its core components, the domestic demand for YRT series bearings are still relatively dependent on imports, domestic YRT rotary table bearings precision parameter standards are also based on international manufacturers. Into the twenty-first century, especially with the national "high-grade CNC machine tools and basic manufacturing equipment," the start of the special, greatly promoting the development of machinery and equipment industry, "high-speed, precision, composite, intelligent" machine tool development process has been further accelerated! Accelerate!
