44.53mm(1.753150"), High Quality Chrome Steel Balls For Bearing, G40
Profile
GCr15 steel has a small alloy content and good performance. It is currently the most widely used bearing steel. It will have good performance such as uniform organization and relatively high hardness.high wear resistance and contact fatigue strength, good thermal processing performance after quenching and low temperature tempering. Contains less alloy elements and is relatively cheap.GCr15 bearing steel, containing C0.95-1.05, Mn0.25-0.45, Si0.15-0.35, S≤0.025, P≤0.025, Cr 1.40-1.65, Mo≤0.10, Ni≤0.30, Cu≤0.25, Ni+ Cu≤0.50.
From the perspective of application categories, steel balls can be divided into two categories: wear-resistant steel balls in the crushing industry and bearing steel balls in the precision bearing industry.
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. Steel ball is a general term for steel ball, steel segment and special-shaped grinding body. According to the appearance, it can be divided into a round ball (general narrowly defined name), capsule ball, elliptical ball, hollow ball, multi-faceted ball, multiple missing ball (with dimples on the surface), etc.
Steel balls are widely used in bearings, hardware, electronics, mechanical equipment, electric power, mining, metallurgy and other fields.
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.
Solid Chrome Steel Balls
Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each steel ball.
Ball hardness is controlled within the 60-67 HRC range as measured on parallel flat surfaces.
Bearing balls are used in automotive applications, for semi-precision bearings, and in commercial applications.
Advantage
- ISO 9001:2008 Provides higher quality and durability, reducing replacement and maintenance cost.
- Our promise: you won’t find any defect,flats,pits,soft spots,and cuts.
- Cost-effective.
- They are solid balls without magnetic but they can be attracted by magnet.
