Advantages of Stainless Steel Material：Made of stainless steel, it has super corrosion resistance, not afraid of humid, acidic or alkaline corrosive environments. It can maintain stable performance for a long time, reduce the frequency of daily maintenance, extend the service life and ensure the continuous and efficient operation of equipment.
Standard Contact Angle Design：The contact angles are divided into the common 15° (70C type) and 25° (70AC type). This standardized design enables it to handle radial and axial loads with ease, reasonably distributing the forces and ensuring the smooth operation of the bearing under complex working conditions.
Precision Component Machining Technology：The rolling elements are carefully ground from high-quality steel, with a mirror-like smooth surface and dimensional accuracy reaching the micrometer level, fitting closely with the raceway to effectively reduce the friction coefficient; the rings have gone through fine processes such as forging, turning, grinding and heat treatment, with excellent roundness, cylindricity and surface hardness, providing solid support for the rolling elements.

High Load-bearing and Stability：With its unique contact angle and high-quality materials, it can carry large radial and axial loads simultaneously. It is often used in key parts such as machine tool spindles and precision mechanical transmissions to ensure the stable operation of equipment under high-speed and heavy-load working conditions.
Low-noise and Smooth Operation：The precise cooperation of all components results in minimal vibration and extremely low noise during operation, creating a quiet working environment for precision machining and measuring equipment and ensuring that high-precision operations are not interfered with.
Wide Environmental Adaptability：The characteristics of stainless steel enable it to easily cope with the harsh environments of the food, pharmaceutical and offshore engineering industries, meeting diverse application requirements and broadening the application fields of bearings.

Application

The bearings can be used in the following industries

Machine Tool Industry：As the core support components of CNC machining centers, precision grinding machines and other machine tools, it drives the precise cutting of tools, helps to manufacture high-precision parts and improves product quality.
Precision Instrument Manufacturing：Used in coordinate measuring machines, optical microscope focus adjustment mechanisms and other equipment, it ensures the high precision and stability of microscopic manipulation and promotes the accurate development of scientific research and detection work.
Special Industrial Fields：In food processing production lines, offshore oil extraction equipment, chemical reactor stirring systems, etc., it adapts to harsh working conditions and ensures the reliable operation of equipment and the continuity of production.
