China NBR won a new utility patent: Innovative deep groove ball bearing manual ball embedding process

The latest news, according to data from the enterprise query platform,China NBR (stock code 002708) has recently added a utility model patent to its intellectual property library. The patent name is "Innovative device for manual ball embedding of deep groove ball bearings", and the patent number is CN202300390.8, the patent authorization date is confirmed to be June 11, 2024.

Patent overview: This utility model focuses on the innovation of manual ball embedding process for deep groove ball bearings. The design includes a fixed base, eccentric assembly, power transmission column unit and blocking block, which are arranged on the fixed base. The eccentric assembly is subdivided into a double shaft seat, a shaft, a pressure arm, an eccentric wheel and a bearing. The pressure arm is connected to one end of the shaft through a positioning column. The eccentric wheel is fixed on the shaft and can be driven by the pressure arm to rotate with the shaft. The outer ring is installed close to the eccentric wheel. The force transmission column unit includes a positioning plate, a force transmission column and a spring. The force transmission column is set in the force transmission column hole of the positioning plate and can move freely along the axial direction. The spring is installed on the force transmission column. This device is designed to provide easy and safe manual ball embedding operation while ensuring cost efficiency and stable output of instant loading force.

This year, NBR's total number of new patent authorizations was 12, a year-on-year decrease of 7.69%. Referring to the company's 2023 financial report, Guangyang Co., Ltd. invested 93.9565 million yuan in research and development that year, a year-on-year growth of 18.65%.
