KG047AR0 Bearing Product Overview & Core Advantages
The KG047AR0 is a high-performance Angular Contact Ball Bearing designed for applications requiring exceptional precision and reliability. As a thin section bearing with a single row construction, it provides an optimal balance between load capacity and compact design. This bearing excels at handling combined loads—simultaneously managing substantial radial forces and significant axial loads in one direction—thanks to its specified 30° contact angle. Manufactured to ABEC-1 precision standards with chrome steel components and brass cage, it delivers consistent performance in demanding industrial environments.
