1. BPW axle type : 12T, 14T, 16T, 18T, 20T
2. Axle tube is 20Mn2 seamless pipe , through one-pipe press forging and heat-treatment , has strong carring capacity and high strength .
3. Spondle material is 20Mn2 over all forging and heat-spondle treatment, has high strength .
4. Spindle and tube through high strength submerged axc welding , safe and reliable crack detection .
5. Both of the spondles and used two headed CNC lathe process together , keep the spindles coaxiality , the journal was grinded , high precision .
6. The hole of brake bracket was welded and than six hole boring process the true position was well , so it was can location high accuracy .action to improve the efficiency of the system .
