Product features:

                                              ● One-piece high-quality low-alloy steel shaft tube, with strong bearing capacity, long life, light weight and excellent  

                                                 performance;

                                              ●The bearing position adopts high-frequency quenching and has strong fatigue resistance;

                                              ● Adopt high-performance asbestos-free brake friction plate, so that the braking performance is good and the wear-resisting

                                                 life is long; the braking system with high processing precision makes the braking performance more stable;

                                              ●The camshaft is equipped with a special sealing element to ensure that the grease does not enter the brake drum to ensure 

                                                safety;
