Achievement in Steel Rolling Mill Bearings
2022-03-21 10:27:35
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.

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.
