In recent years, the localization of high-precision turntable bearings in China has accelerated markedly. As a core component of high-end equipment such as CNC machine tools and aerospace systems, YRT turntable bearings feature high axial and radial load-carrying capacity, high tilting stiffness, and exceptional precision; their rotational accuracy can reach P4 or P2 grades, with repeatability consistently within 1.5 micrometers, thereby meeting the stringent requirements of precision machining, metrological testing, and other applications.
In terms of technological breakthroughs, domestic enterprises have optimized the three-row roller bearing design and adopted advanced processes such as nano-precipitation–strengthened bearing steel and intelligent grinding systems, resulting in a threefold increase in bearing fatigue life, a 60% reduction in residual stress, and deformation controlled within 0.02 millimeters. For example, the YRT series bearings manufactured by companies such as Luoyang Lake Precision Machinery now cover the entire product range; some models have been validated by leading international firms like Germany’s DMG and are exported to global markets.
In terms of expanding application areas, domestically produced YRT bearings are not only widely used in traditional fields such as CNC machine tool rotary tables and five-axis machining centers, but have also successfully penetrated strategic high-end markets like aerospace and semiconductor equipment. With the strengthening of collaborative innovation across the industrial chain, domestic bearings have continuously achieved breakthroughs in key performance indicators—including material purity, maximum rotational speed, and stability of friction torque—while the localization rate has steadily increased, thereby providing solid support for the development of high-end equipment manufacturing.
