MANUFACTURING

WZA Bearing Production:

With international advanced technology and sufficient equipment, WZA strictly controls the quality of every bearing from the first step drawing design to the last step products delivery, accompany with 100% test right to ensure every bearing perfect, concise and accurate.

Drawing

First of all,optimization of drawing design is based on customer’s requirements, bearing application fields and bearing working condition.

Material

WZA adopts high-quality Chrome steel with high purity and conducts rigorous tests to verify the quality.

Forging

USE dedicated forging equipment, in which the steel bar is heated through intermediate frequency inductance and the thermometer is used to measure temperatures of different parts of the bar. After heating and hydraulic hot shearing, the products are forged to meet requirements of rolling. After that, in order to ensure to products to achieve excellent tolerance performance in size and geometric shape, rolling with executed through CNC ring rolling machine.

Heat treatment annealing

Spheroid zing annealing is adopted for all WZA products, which is characterized by product temperature uniformity and good internal structure, laying a good foundation for the next process of turning and hardening.
