ZWZ announces a technology breakthrough in silicon steel sendzimir mill bearing

Because of the high speed and large rolling force, the support roll bearing of Senjimir Mill of Silicon Steel requires high precision, high load, high speed and high reliability. The bearing is lubricated with oil mist inside, which is difficult to process. Previously, the bearing widely used in the cold rolling industry was monopolized by foreign brands.

ZWZ conducted research and analysis from each link of design, process and processing. After optimizing the process and repeated trial production, various indicators of the product were recognized by the customer and the localization was successfully achieved. It is reported that the orders for this bearing are growing steadily, and engineers and front-line operators are accelerating the transformation of achievements, injecting new momentum into the high-quality development of the company.
