CHG Bearing—Precision Bearings for a Better Tomorrow

Luoyang Huigong Bearing Technology Co., Ltd. (CHG Bearings), established in 1998, is a high-tech enterprise specializing in the design, R&D, manufacturing, and sales of long-life rolling mill bearings, high-precision thin section bearings, and high-end large rolling elements. The company is located in Luolong District, Luoyang, China, covering an area of 39,330 square meters. CHG employs more than 350 people, including a strong technical team, and operates over 150 production machines. In 2023, the company achieved an annual output value of approximately CNY 150 million.

Rolling mill bearings are CHG’s flagship products and are widely recognized in the domestic non-ferrous metals industry. Designed for high precision, heavy loads, fatigue resistance, and long service life, these bearings feature an inner diameter range from 90 mm to 1,400 mm. They are widely used in non-ferrous and ferrous metal rolling mill equipment, metal processing lines, wire and cable production equipment, and other industrial applications.

High-precision thin section bearings are available with inner diameters from 1 inch to 40 inches, and accuracy up to P2 level. These products are extensively applied in precision equipment fields such as medical devices, automation systems, and optical & measurement equipment.

High-end large cylindrical, tapered, and spherical rollers adopt a logarithmic-crowned profile design. With diameters from 15 mm to 300 mm and lengths from 20 mm to 400 mm, the rollers can meet G1, G1A (Grade I), G2, and G2A (Grade II) precision standards, and are widely used in wind power bearings, rolling mill bearings, and various large-size roller bearing applications.
