50.92mm(2.0047244"), 50.72mm To 50.91mm , High Quality Large Solid
Steel Balls For Big Bearing , G40
Introduction
GCr15 steel is the representative steel of high carbon chromium
bearing steel, with good overall performance, high and uniform
hardness, high wear resistance and contact fatigue strength, and
good hot workability after quenching and tempering. After
spheroidizing annealing, although it has good workability, it is
sensitive to the formation of white spots.
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 automotive applications.
Bearing steel balls have a long history of use in the precision
bearing industry and service life, and are more widely used. It can
be said that most of the rotating places have steel balls, commonly
known as steel balls.
Mainly used to manufacture steel balls, rollers and bushings on
drive shafts of internal combustion engines, electric locomotives,
machine tools, tractors, rolling equipment, drilling machines,
railway vehicles and mining machinery.
Steel balls are divided into grinding steel balls, forged steel
balls and cast steel balls according to the production process.
According to the processing materials, it is divided into bearing
steel balls, stainless steel steel balls, carbon steel steel balls,
copper bearing steel balls and alloy steel balls.
Among them, the bearing steel ball is an important basic component
in the industry, and the alloy steel ball is a spherical shape made
by forging, spinning, rolling, and casting with carbon, chromium,
manganese, molybdenum and other metal elements as the main
components. metal element. Special-shaped ferroalloy wear-resistant
body is an important part of crushing industrial mine balls and
cement balls.
We mainly produce chrome steel with sizes ranging from 7.9375mm to
82.55mm. The main material is high chromium GCR15 or GCR15SiMn.
Most importantly, we can customize products to meet the various
needs of customers.
