With increasing demands for bearing performance in high-precision fields such as automation, aerospace, and medical equipment, the precision grade standards of thin section bearings have garnered significant attention. Thin section bearings, with their unique small cross-sectional design and high-precision performance, play a crucial role in applications requiring space-saving and high reliability.

Classification of Precision Grades for Thin Section Bearings

The precision grades of thin section bearings are typically classified according to the International Organization for Standardization (ISO), the American Bearing Manufacturers Association (ABMA), and the German Industrial Standard (DIN). Common precision grades include P0 (normal grade), P6 (precision grade), P5 (high precision grade), P4 (super precision grade), and P2 (ultra-precision grade). Among them, P0 is the lowest precision, while P2 is the highest precision.

• P0 (Normal Grade): Suitable for general industrial applications with relatively low precision requirements.
• P6 (Precision Grade): Higher precision, suitable for automation equipment and some machine tool applications.
• P5 (High Precision Grade): Used in applications requiring high precision and speed, such as high-speed motors and robotic arms.
• P4 (Super Precision Grade): Applied in high-demand fields such as aerospace and precision machine tool spindles.
• P2 (Ultra-Precision Grade): Suitable for applications requiring the highest precision, such as optical equipment and experimental instruments.

    The higher the precision grade of a thin section bearing, the more complex the manufacturing process, and consequently, the higher the production cost. However, its performance and reliability also improve significantly. The choice of precision grade depends on the specific application requirements and the working conditions of the equipment.

    The precision of LYNBC bearings can reach P0/P5/P4/P2 grade, which is suitable for special working conditions such as medical equipment, on-board optics and robots.
