1. Yuanzheng axle beam use 20Mn2 seamless pipe, through one-piece press forging and special heat-treatment, which has great over loading capacity and high intensity. 2. Yuanzhengaxle spindle,which was processed by digital controlled lathe, is made of alloy material. The bearing position is processed by the method of hardending operation,therefore the bearing can be fixed by hand instead of heating, also convenient for maintain and fixing. 3. Yuanzheng axle spindle is connected by the by submerged -arc welding, which make the whole beam more reliable and solid. 4. Yuanzhengaxle bearing position is used the grinding machine to keep the bearing at the same level, after processing, it can assure that the concentricity within 0.02mm strictly. 5. Yuanzheng axle grease lubricant is supplied by EXXON Mobile which could provide high lubricating performance and protect bearing well. 6. Yuanzheng brake lining is high performance, non-asbestos, non-pollution and long service life.To make check and replace easily, also come with the position of the exhaustion to remind customer to check and maintain. 7. Yuanzhengbearing is adopted famous brand in China, with the advantages of over loading capability, High rotating speed, good intensity, abrade resistant and heat resistant. 8. Yuanzheng wheel hub and brake drum use the international standard material of ball iron and gary iron separately, which has the advantages of over loading capability, abrade resistant, heat resistant and do not distort. 9. Yuanzhengaxle be National Automobile Monitor and Inspection Center certified ,axle shaft that undergoes over 1.2 million times of Fatigue testing and built to meet or exceed national industry standards. Original packing, mainly based on the customer's requirements.
