Achievement in Steel Rolling Mill Bearings | Esgbearing.com

 The working conditions for steel mill bearings are demanding as they will face dust, steel particles, water, heat, high speed and high temperature.


Four-row cylindrical roller bearing works as the radial cylindrical roller bearings on the roll neck. Its performance values the most for the rolling mill bearings.



ESG Bearing, as an expert on steel rolling mill bearings. We are always improving ESG quality to better meet steel mill’s requirements. With years of testing, ESG Bearing now announced that ESG has successfully make our four-row cylindrical roller bearings with steel cage.


The working life, wear-resistance and performance of the radial cylindrical roller baring with steel cage proves to be better than bearing with brass cage.


Succeed in steel cage on rolling mill bearings


ESG Bearing, specializes in making high quality rolling mill bearings for steel mills of bars, angles, beams, coil and sheet, etc.

 

↑ higher load

+ wear resistance

→ longer working life

compared with brass cage


About This Achievement

ESG Bearing has been spent about 3 years for the testing and improving our production of radial roller bearing with steel cage. And now the overall feedback for steel cage is good with ESG’s control for every processing steps.

Radial roller bearings for rolling mill stands are working in the poorest conditions with heat, heavy load, high speed, particles, and water. Early type of the roller bearings usually used brass cage for good tenacity and vibration damping.

With the material and technology, we are having now, ESG’s roller bearings with steel cage will have a better performance of tensile strength, peel strength, wear resistance, vibration damping than bearing with brass cage. It will be more widely used for more steel mills.

Reveal the skin care glass packaging plating process

图片
  Skincare glass packaging   plays a crucial role in the beauty industry, and its radiant appearance is often an important factor in attracting consumers' attention. However, the secret behind this is not only the glass itself but also the plating process hidden on its surface. In this article,   we will discuss in depth the plating process of skin care glass packaging , revealing the mystery behind it. Surface plating technology  is the plated parts (products) immersed in a potion containing metal ions to be plated and connected to the cathode, the other end of the potion placed on the appropriate anode (soluble or insoluble), after the DC, the surface of the plated parts that is precipitated a layer of metal film method. A simple understanding of the physical and chemical changes or combinations. It is commonly used in skin care glass packaging materials to add texture to the appearance and protective properties. This technique can involve coating the surface of t...
