YRT turntable bearing is a bearing with high precision requirements and high technical threshold, which is mainly used in the rotary table, chuck, milling head, etc. of machine tools.
Before 2007, YRT turntable bearings were basically monopolized by Schaeffler of Germany.
For this reason, LYHY Bearing Technology Corporation decided to develop YRT turntable bearing, hoping to break the monopoly of Schaeffler.
In 2008, the company obtained an order from DMG, a German machine tool enterprise.
Germany DMG requires the rotation accuracy of YRT turntable bearing to reach two microns.
In 2009, LYHY sent bearing samples to DMG of Germany for the second time, which passed the acceptance successfully.
Through continuous technical innovation, the company has broken the long-term monopoly of YRT turntable bearings in China.
The YRT turntable bearings developed by LYHY account for 80% of the Chinese market. Half of the YRT turntable bearings produced by the company are exported to the international high-end machine tool market. The users include many leading enterprises in the global machine tool industry.
After the success of YRT turntable bearings for high-precision machine tools, LYHY expanded its business to the field of industrial robots.
The special bearing for harmonic reducer of industrial robot is one of the core components of industrial robot, which affects the accuracy, stability and reliability of industrial robot. Due to high precision requirements and great processing difficulties, the special bearings for harmonic reducers of industrial robots are almost monopolized by Japan, Germany and other countries.
In terms of material selection, heat treatment process upgrading, the company has upgraded key equipment. After more than 60 times of continuous technical upgrading and improvement, the bearing developed by the company has been tested, and its technical indicators are comparable to those of similar products in Japan. Its quality and performance have reached the international advanced level, but its price is only one third of that of foreign products.
At present, the company has occupied 30% of the industrial robot reducer bearing market, and has supplied in batches for ABB, Kuka, Xinsong and other well-known industrial robot enterprises.
