📝 Category Detail

7200C series are high-precision single-row angular contact ball bearings featuring a 15° contact angle (α=15°), optimized for ultra-high-speed operation with excellent radial load capacity and moderate axial load performance. Compared to larger contact angle variants (AC/B), the C-type design minimizes friction and heat generation, making it the ideal choice for high-speed, precision machinery applications.

Manufactured from premium GCr15 (100Cr6) high-carbon chromium bearing steel with precision grinding and strict heat treatment, these bearings deliver exceptional rotational accuracy, dimensional stability, and long service life. They support flexible paired installation configurations (DB/DF/DT) to meet bidirectional axial load requirements, with standard metric dimensions ensuring full interchangeability with international brands.

Category Overview

Angular Contact Ball Bearings are designed with contact angles between the balls and raceways, enabling them to carry combined radial and axial loads simultaneously as well as unidirectional thrust loads. With high rigidity, high running accuracy, and high-speed performance, they are widely used in precision machinery, machine tools, pumps, motors, and equipment requiring precise axial positioning.We supply single-row, double-row, and matched bearing configurations to meet different precision, speed, and load requirements.
