A patent for a wear-resistant device to protect deep groove ball bearings was obtained by Harbin Precision Bearing
On January 6, 2025, HRB Precision Bearing obtained a new patent issued by the State Intellectual Property Office. This patent is for "An anti-wear device for protecting deep groove ball bearings", and its authorization announcement number is CN 222254723 U. The application for this patent was submitted in May 2024.
The patent abstract introduces an innovative design to reduce the wear of deep groove ball bearings during operation. This new device sets a special rolling element reserved space between the inner and outer rings of the bearing, and places multiple rolling elements at equal distances inside this space. Each rolling element is equipped with an arc-shaped cage on both sides to ensure that they are evenly distributed and reduce direct friction between the rolling elements. There are fixing holes at both ends of the cage, which are connected to the screws on the rotating ring through the sealing cover to ensure that all components are stably installed.
The key to this design is that it allows the cage to suspend in the reserved space, avoiding contact with the inner and outer rings of the bearing, thereby reducing additional friction. This improvement not only improves the working efficiency of the bearing, but also extends its service life.
The new patent of HRB Precision Bearing reflects the company's unremitting efforts in improving bearing performance and technological innovation, while also bringing more durable and efficient bearing solutions to the market.
