34.50mm(1.3582677") E52100,100Cr6, Grade 28, High Chrome Steel Ball For Bearing
Introduction
Chromium (Gcr15, 100Cr6, 52100, SUJ2) steel balls, also called bearing steel balls. The high-precision chromium steel ball contains chromium and has excellent surface quality and high bearing capacity due to being quenched.
Throughout the manufacturing process, statistical process control can ensure tolerance accuracy, good surface finish and consistent high quality. It is most widely used in the ball and roller bearing industry and various wind power applications.
High carbon chromium bearing steel refers to the high carbon alloy steel with 1.40-1.65% of chromium. Its features are the micro organization after heat treatment is comparatively even and stable, good abrasion, high stress fatigue strength, good size stability and anti-abrasion.
Steel balls are divided into grinding steel balls, forged steel balls, and cast steel balls according to the production process. According to the processing material, it is divided into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls and alloy balls. Among them, the bearing steel ball is an important basic component of the industry, and the alloy steel ball is a spherical shape formed by forging, spinning, rolling and casting with carbon, chromium, manganese, molybdenum and other metal elements as the main added metal elements. Shaped ferroalloy wear-resistant body, it is the most important part of today's crushing industrial mine ball and cement ball.
Bearing steel balls have a long history of use in the precision bearing industry and life, and they are more widely used. It can be said that most of the places where there is rotation, there are steel balls, commonly known as steel balls and balls.
The surface of our chrome steel balls is extremely precise and smooth, ensuring that you will not find any defects such as flatness, dents, soft spots and cuts.
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.
The best precision, make your bearing roll smoother.
