NG140AR0 Bearing Product Overview & Core Advantages
The NG140AR0 is a high-performance Angular Contact Ball Bearing designed for demanding applications requiring exceptional precision and reliability. Manufactured to ABEC-1 tolerance standards, this inch-series bearing features a generous 30° contact angle, enabling it to support significant combined loads—simultaneously handling high radial loads and substantial thrust loads in one direction. Its Endura-kote Chromium Plating provides superior corrosion resistance, while the single row design maintains a compact cross-section, making it an ideal solution for high-rigidity, precision mounting arrangements.
