Dentail

Structural Characteristics：

Double-row Deep Groove Ball Arrangement：This bearing features a double-row deep groove ball design. Compared with single-row bearings, it can carry larger combined radial and axial loads and performs well under complex force conditions.
Crown Steel Retainer：Equipped with a unique crown steel retainer, which is shaped like a crown. It not only has high strength to firmly support the balls but also can effectively guide the ball movement at high speeds, reducing collisions and friction and enhancing the smoothness of operation.
High-precision Balls and Rings：The balls are made of high-quality steel and have undergone fine grinding, with smooth surfaces and precise dimensions to reduce running friction. The rings have also gone through precision machining and heat treatment, with extremely high precision in roundness, cylindricity, etc., and fit closely with the balls to ensure overall stability.

Application

The bearings can be used in the following industries

Industrial Manufacturing：Widely used in machine tools, motors and other equipment, providing stable support for machining and power transmission, ensuring production accuracy and efficiency.
Automotive Industry：It plays a role in parts such as automobile hubs and transmissions, adapting to complex road conditions and variable driving conditions, helping automobiles to drive smoothly.
Home Appliances：For example, in the motor components of air conditioners and washing machines, it reduces operation noise, improves user experience, and ensures the long-term stable operation of the equipment.
