Thin-walled Constant Cross-section Deep Groove Ball Bearings

The most prominent feature of this series of bearings is their thin-walled and constant cross-section. While ensuring a certain strength, they greatly reduce their own weight and save installation space, facilitating the compact design of equipment. It is especially suitable for precision instruments and small equipment that are sensitive to space and weight.

Thin-walled Constant Cross-section Design：The most prominent feature of this series of bearings is their thin-walled and constant cross-section. While ensuring a certain strength, they greatly reduce their own weight and save installation space, facilitating the compact design of equipment. It is especially suitable for precision instruments and small equipment that are sensitive to space and weight.
Deep Groove Ball Structure：Inheriting the advantages of deep groove ball bearings, the rolling elements fit closely with the deep groove raceways of the inner and outer rings, enabling them to bear a certain radial load and a small axial load simultaneously, operating smoothly and adapting to various working conditions.
Precision Manufacturing Process：The rolling elements are made of high-quality steel and finely ground, with a smooth surface and high dimensional accuracy, fitting well with the raceway to reduce friction; the rings have gone through processes such as forging, precision turning, grinding and heat treatment, with excellent roundness and cylindricity, ensuring overall performance.

Space and Weight Advantages：The thin-walled structure "lightens the load" and "makes room" for precision equipment, such as micro drones and high-end watch movements, enabling them to achieve more functions in a limited space, improving portability and flexibility.
Good Load-bearing Adaptability：Although thin-walled, it has reliable load-bearing capacity and can handle the regular forces in daily use. It operates stably in fields such as small motors and office equipment, reducing the risk of failure.
Low-noise Smooth Operation：The precise cooperation of components makes the operation quiet and smooth. It creates a quiet working environment for equipment sensitive to noise, such as precision medical instruments and acoustic testing equipment, ensuring accurate operation.

Application

The bearings can be used in the following industries

Precision Electronics：Widely used in the internal micro motors and cooling fans of smart phones, tablet computers, etc., ensuring stable heat dissipation and smooth operation of the equipment, improving user experience.
Medical Devices：Like the transmission parts of small portable medical devices such as blood glucose meters and blood pressure meters, it provides precise and quiet power, assisting medical detection and ensuring accurate data.
Aerospace Microsatellites：In the attitude control systems and energy conversion devices of microsatellites, it undertakes key tasks with its light body, helping the satellites to operate efficiently and saving launch costs.
