OBT Front axle feature:
1.OBT 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.OBT axle 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.OBT axle spindle is connected by the by submerged -arc welding, which make the whole beam more reliable and solid.
4.High performance premium non-asbestos brake linings --- extend service life. Improved seals at camshafts --- protect the brake drums from the grease lubricant,more safety.
