Grade 40 Hardened Steel Balls E52100 50.86mm 2.0023622" Corrosion Resistance

50.86mm(2.0023622") Grade 40 Hardened 52100 Chrome Steel Ball For Bearing
 
Introduction

GCr15 steel has low alloy content and good performance. It is the most widely used bearing steel in the world. it will have higher hardness and uniform good structural properties after quenching and low temperature tempering. This steel has general cold working plasticity, poor welding performance, and high sensitivity to the formation of white spots and temper brittleness.

Chrome steel balls in the 50.72mm to 50.92mm group are widely used in precision ball bearings and many other industrial applications. The chromium steel balls are hardened and have excellent surface quality, high hardness and high load carrying capacity. Chrome steel balls also have long life service and resistance to deformation.

High-quality graded hardened chrome steel ball bearings are made of AISI 52100 chrome steel. Hardened to 60-67 Rockwell hardness equivalent to 700-900 HV (Vickers hardness), and hardened to the entire ball. These are the same materials as the hardened steel balls used to make bearing components, and have a high service life and long service life. The chromium steel ball contains high chromium and has excellent surface quality and high load carrying capacity due to quenching.

The surface of our chrome steel balls is extremely precise and smooth, ensuring that no defects such as flatness, dents, soft spots and cuts will be found.

We mainly produce chrome steel with sizes ranging from 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn. Our balls are mainly used in the wind energy industry.

Manufactured in compliance with the following international standards: AISI52100 / EN31 / BS534A99 / W1.3505 / BS535A99 / UNI100C6 / AFN100C6 / DIN100C6 / JIS G4805 SUJ2.

Properties and Advantage

[High-quality material] Made of high-quality chromium steel, high-grade bearing steel, corrosion resistance, high precision and high hardness. Polished surface, smooth without burrs, standard shape and high precision, completely round.

[Anti-rust] Corrosion resistance and high oxidation resistance. It is also suitable for humid environments. The surface is coated with a small amount of grease to improve lubrication and prevent corrosion and rust.

[Long use] The heat treatment process can make the bearing ball stronger and bear high pressure and wear resistance.

[Wide application] Widely used in wind turbine bearings, yaw bearing, slewingring bearing and so on.

Influencing Factor

①The influence of material density: steel balls, cast iron balls, alloy steel balls, etc. Different materials have different densities. The density of steel is higher than that of cast iron. The density of alloy steel is based on the density and content of the main alloying elements.

②The influence of steel ball manufacturing method: Rolled and forged steel balls have a dense structure, so the density is very high. The structure of cast steel balls, cast iron balls or cast alloy balls is not very dense, and even has pores, so the density​​​ is lower.

③The influence of the metallographic structure of the steel ball: the density under different crystal structures such as martensite, austenite, bainite, and ferrite is also different, which also affects the fineness of the crystal.

④The influence of chemical composition elements: the different chemical compositions contained in the finished steel ball, such as iron, carbon, chromium, manganese, sulfur, phosphorus, etc., will affect the hardness and impact wear of the steel ball to different degrees. Generally speaking, if the chromium content is large, the steel ball has higher wear resistance.
