Introduction
Chrome steel is one of a class of non-stainless steels, such as AISI 52100, En31, SUJ2, 100Cr6, 100C6, DIN 5401, and can be used for bearings, tools, drill bits and utensils.
ASIA 52100 chrome steel balls are used in the ball and roller bearing industry and various automotive applications. These chrome steel balls have excellent surface quality. Through quenching, they have excellent wear resistance, high hardness and high load carrying capacity.
Bearing balls are special highly spherical and smooth balls that are most commonly used in ball bearings, but are also used as components such as flywheel mechanisms. There are many different levels of the ball.
Ball bearing is a type of rolling bearing that uses balls to maintain the spacing between bearing races.
The purpose of ball bearings is to reduce rotational friction and support radial and axial loads. It accomplishes this by using at least three seats to accommodate the ball and transfer the load through the ball. In most applications, one seat ring is fixed, while the other seat ring is fixed to the rotating component (such as a hub or shaft). When one of the bearing races rotates, it also causes the balls to rotate. Because the balls roll, their friction coefficient is much lower than when two flat surfaces slide against each other.
We mainly produce chrome steel with sizes ranging from 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn. Our balls are mainly used in the wind energy industry.
Our products enjoy high evaluation and satisfaction among customers. Most importantly, we can customize products to meet the various needs of customers. According to customer requirements, steel balls can be produced in accordance with Chinese standard GB/T 308, international standard ISO 3290, American standard ANSI/ABMA, German standard DIN 5401, Japanese standard JIS B 1501, etc.
Production Process
The post-processes of steel ball production, namely, automatic steel ball cleaning, automatic appearance inspection (automatically reject unqualified products), automatic rust prevention, counting and packaging, which are all key to the quality of steel balls. Steel ball appearance inspection is an indispensable process in the process of steel ball processing. The appearance inspection of steel balls mainly includes the inspection of surface scratches, rust, and surface spots. Steel ball production process: stamping - smooth grinding- quenching - hard grinding - appearance inspection - fine grinding - cleaning - rust prevention - finished product packaging.
