Introduction
Steel ball is a fundamental part of industry. From ball pen to airplane, steel ball plays a very important role in various industries. To divide it in material, it could be divided into carbon steel ball, bearing steel ball, stainless steel ball etc. Carbon steel ball has the property of low price and high hardness. Therefore, it is widely used in bicycle, bearing, pulley, sliding rail, universal ball, etc. Bearing steel ball has the property of excellent surface finish, high hardness, high load carrying capacity, excellent wear and deformation resistance etc. It is mainly used in precision ball bearing. Meanwhile, it could also be used in bicycle, motorcycle, automobile, sliding rail, home appliance, electronic industry, chemical industry etc.
In addition, steel balls sizes of 30mm -82.55 mm are our company's main products used for large wind turbine bearings and slewing bearing.
Based on customer'srequirement, the steel balls could be produced according to China Standard GB/T 308,ISO 3290, ANSI/ABMA, JIS and DIN 5401etc.
Bearing balls are special highly spherical and smooth balls, most commonly used in ball bearings, but are also used as components, such as flywheel mechanisms. There are many different class of balls. Such as G3, G5, G10, G20, G28, G40, G60, G100, etc
Our company's bearing steel balls are made of high-quality high-carbon chromium bearing steels GCr15 and GCr15SiMn. They are the best choice for various high-precision bearings.The best precision,make your bearing roll smoother.
Choose us as your Precision Ball Supplier with the Most Complete Variety of Precision Balls, Ball Materials and Technologies.
