Bearing Ball Introduction

Ball according to the production and processing technology is divided into grinding steel balls, forged steel balls, cast steel balls. According to the processing material is divided into bearing steel ball, stainless steel ball, carbon steel ball, copper bearing ball ball alloy ball. Among them, the bearing steel ball is an important basic component of the industry. The alloy steel ball is a spherical (spherical) ball-shaped ball joint formed by means of forging, spinning, rolling and casting with carbon, chromium, Ferroalloy wear-resistant body, it is the smashing industrial mine ball today, the most important part of cement ball
