1.OBTaxle beam use 20Mn2 seamless pipe, through one-piece pss forging and special heat-treatment,which has great over loading capacity and high intensity.

2.OBTaxle spindle,which wasprocessed 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.OBTaxle spindle is connected by the bysubmerged -arc welding, which make the whole beam more reliable and solid.

4.OBTaxle 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.OBT axlegrease lubricant is suppliedby EXXON Mobilewhich could provide high lubricating performance and protect bearing well.

6.OBTaxlebrake 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.OBT Axlebearing is adoptedfamous brandin China, with the advantages of over loading capability, High rotating speed, good intensity, abrade resistant and heat resistant.

8.OBT Axlewheel hub and brake drum use theinternational standard material of ball iron and gary ironseparately, which has the advantages of over loading capability, abrade resistant, heat resistant and do not distort.
