The customer is not able to purchase the special bearing from the market cause they need the bearing is non-standard and customized. ZWA is professional in designing and producing customized products. After brief communication with the customer, ZWA set up a professional engineering group. This group carried out on-site inspection, learned the detailed application position of the bearing, the working condition of the equipment and possible accidents may happen in the operation. Based on the learned information, ZWA proposed the detailed technical solutions. After checking with the customers, the solutions got approved from the customer. Even the theoretical solution is at hand, but the production is still a challenge. The production department and the engineering group researched a brand-new techniques for production, purchased the new production equipment, formed the new process tooling, ordered the new testing equipment and developed the new testing methods. Meanwhile, in order to guarantee the quality of the bearing, in the production, even more strict quality control is executed.
