34.40mm 1.354331" Metal Bearing Steel Ball G28 For Angular Contact Ball Bearing

34.40mm(1.354331"), Metal Bearing Steel Ball For Angular Contact Ball Bearing, G28

Introduction

GCr15 bearing steel is a kind of high-carbon chromium bearing steel with low alloy content, good performance and the most useful. It has high hardness, uniform good structural properties, good wear resistance and high contact fatigue performance after quenching and tempering. The steel has the characteristics of moderate plasticity, low cutting performance, poor welding performance, high sensitivity to white spots and temper brittleness. GCr15 bearing steel, containing C0.95-1.05, Mn0.25-0.45, Si0.15-0.35, Cr 1.40-1.65.

Application field

Gcr15 bearing steel balls are widely used in high-speed and low-noise bearings, bicycles, motorcycles, automobiles, slide rails, general-purpose balls, luggage, and electronic industries, and can also be used to grind other media.

Chrome steel ball knowledge

Chrome steel balls play a very critical role as an important accessory in the bearing. Therefore, the use effect of the bearing is closely related to the service life and the accuracy of the bearing steel ball. and the size of the hardness is related to the crushed load value of steel balls.

Crushed load is an important performance indicator of the bearing steel ball. Semi-finished steel balls and finished steel balls in the quenched fire treatment state need to detect crushing loads, such as do not meet the standard, and the entire batch of products may be scrapped. Today, we analyze the factors affecting the insufficient pressure of the chrome steel ball.

1. Quench overheating 2. Quenching crack 3. Material crack 4, shrinkage 5. Slage inclusion; 6, microporous pore; 7, Insufficient tempering; 8, excessive stress.

If you are avoided the above 8 points the quality of the bearing can be greatly improved.

High Precision bearing (chrome) steel ball

Chrome steel and other metal balls are manufactured using the following processe

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.
