ChinaTianqing Bearing Secures New Self-Lubricating Bearing Race Patent, Enhancing Automotive Powertrain Stability
In May 2025, the latest patent information released by the State Intellectual Property Office showed that a new bearing technology of Zhejiang Xinchang Tianqing Bearing Co., Ltd. was authorized for a utility model patent with the patent number CN222894523U and the application time in April 2024. The patent involves a bearing ring structure for automobile engine transmission system, and the key improvement is to integrate the lubrication storage mechanism to optimize the lubrication efficiency during use.
According to public information, the core of this technology is to add a lubrication component on the basis of the traditional bearing ring. The component consists of two symmetrically distributed arc grooves, and a lubricant storage box is connected to the groove body. The surface is designed with a sliding guide groove, and the release control of the lubricant is realized through the linkage device between the push plate and the slider. When the ball surface is worn or the friction increases during the operation of the bearing, the lubrication component can automatically relubricate.
This structural design effectively solves the problem of frequent addition of lubricating oil to traditional bearings during operation, which not only reduces the frequency of manual maintenance, but also reduces the risk of mechanical failure caused by inadequate lubrication, thereby improving the reliability of the overall equipment operation.
From the perspective of technical application, this solution realizes the embedded lubrication function without affecting the original installation space, which is suitable for automotive engine environments with high requirements for space layout. At the same time, since the release of lubricants has a certain degree of controllability, it also helps to extend the service life of bearings and reduce maintenance cycles.
It is not clear whether the patent has entered the product trial production stage, but industry experts pointed out that similar components with "self-lubricating" characteristics are gradually becoming one of the important directions for optimizing high-end automotive power systems.
