G40 Chrome Steel Ball is a high-quality and affordable product from Condar. As a professional steel ball supplier, we have extensive production experience and integrate sales and production. A team of professional and responsible personnel strictly controls quality during the production process and provides core product assurance and services.
The main feature of G40 chrome steel balls is its high hardness. The material we use is high carbon chromium bearing steel, with a Rockwell hardness of up to HRC60-65. It has strong wear resistance and pressure resistance, and can withstand high pressure and impact at work.
1. Powerful performance: G40 chrome steel balls have high hardness, and the density of 7.8g/cm3 helps to balance hardness, toughness, inertia, and stable performance.
2. Economic and durable: These chrome steel balls is suitable for high-load application environments, has a long service life, and is affordable at the factory, with high cost performance.
3. Wide adaptability: Although G40 chrome steel balls are mainly used in bearing accessories, they are not limited to this application. They can also be used in parts and grinding applications in other industries.

The steel ball grade of G40 chrome steel balls is G40, and the grade refers to the precision of the steel ball. The smaller the number, the higher the precision and the better the roundness. We will indicate the data indicators related to G40 chrome steel balls for you below, but choosing the right steel ball still needs to be based on the actual situation. It is not necessarily the case that the higher the grade, the more suitable it is.
