The C&U group is a leading enterprise in the bearing industry, occupying a large share of the bearing market in China. Most of its end customers are well-known automobile brands, such as Beijing Hyundai and South Korea Hyundai. The assembly of C&U cage is not easy to make mistakes to prevent serious accidents caused by improper assembly. As it is required to operate in automotive pulley and one-way bearing, it must be absolutely reliable. After receiving the product demand, engineers of our company worked out a solution: Logo processing on the end face to ensure absolute smoothness and design the chamfering Angle that is easy to be pressed into the loading direction. In addition, the engineer also added an error prevention point on the cage retaining edge, which could not be loaded in the opposite direction. After the proposal was submitted, it not only gave C&U group a new idea to solve the problem, but also gave C&U group a perfect cage supplier with perfect quality and reasonable price. We hope that our services can be spread to every bearing manufacturer, so that the major manufacturers with the least cost, to obtain the greatest harvest.
