7.0mm(0.27559"),Forged Solid Grinding Stainless Steel Ball For Bearing

Introduction

Stainless steel balls are usually produced by forging processes. At this stage, the commonly used stainless steel balls are made of 201, 302, 304, 316, 316L, 420, and 440C.

Definition: Steel that contains more than 12% chromium and is resistant to chemical substances.

Principle: Stainless steel does not rust, but it is not easy to rust.

The principle is that by the addition of chromium elements, a dense chromium oxide layer is formed on the surface of the steel, which can effectively block the re-contact between the steel and the air, so that the oxygen in the air cannot enter the steel, thereby achieve the effect of preventing steel from rusting.

Classification: China National Standards (CNS), Japanese Industrial Standards (JIS) and American Iron and Steel Institute (AISI) use three digits to indicate different stainless steels and are widely cited by industry offices. Among them, 200 series are chromium-nickel-manganese series Austenitic stainless steel, 300 series is chromium-nickel austenitic stainless steel, 400 series chromium stainless steel (commonly known as stainless iron), including martensite and ferrite.

We mainly export stainless steel ball (201, 304, 316, 420,420C,440C,430). also produce chrome steel ball (AISI52100,100CR6,GCR15), carbon steel ball(1015,1010,1045,1085), and other kinds of material ball.

Our steel balls is used in many industrials, such as precision bearings, automotive components (brakes, steering, line shaft), bicycle, agitators, appliances, sliders, quick couplings, machine tool, lock mechanisms, conveyor belts, skates, pens, pumps, castors, measurement instruments, valves, etc.

Established in 2006, Xi'an Machinery & Engineering Import & Export Co.,Ltd.（XMEC) is the successor to Shaanxi Marine and Engineering Import & Export Co., Ltd., which is specialized in importing & exporting mechanical and electrical products, complete equipment, various kinds of vessels and ships, marine equipment and port machinery, electronic and electric products, instruments and meters, minerals and metals, light industrial products, etc. XMEC also engages in different trading activities such as import and export of techniques and overseas project contracting.

With over 20 years of importing and exporting experience, we have good reputation from our customers at home and abroad, our source passed ISO9001:2008 and our products got SGS,RoHS Certificates etc.

Based on almost two decades of continuous efforts and development, our company has become one of the leading domestic facility which can supply high precision steel balls with complete specifications. We mainly produce Chrome steel ball (AISI52100, 100Cr6, GCr15, GCr15SiMn, SUJ2), Stainless steel ball (201, 304, 316, 420, 420C, 440C, 430), Carbon steel ball (1015, 1010, 1045, 1085), Tungsten carbide ball etc., Especially from 7.9375 mm - 82.55 mm high precision size chrome steel balls which are our principal products and used mostly for Wind Turbine Bearing, Slewing Ring Bearing and also the Bearing. The accuracy range of the steel balls we provide is from G10- G1000.

Based on customer’s requirement, the steel balls could be produced according to China Standard GB/T 308.1, International Standard ISO 3290, America Standard ANSI/ABMA Std. 10A, Germany Standard DIN 5401, Japan Standard JIS B 1501 etc.

With features of low-noisy, high-accuracy, best-service, our products have been widely used in various industry fields, such as aerospace industry, bearing, bicycle, auto industry, medical industry, electronic field, military industry, precision instrument and so on. They are all sold to overseas market with most competitive price and high quality.
 

We are looking forward to cooperation with you at the basis of mutual benefit in the near future.
