T/CAAMM 50-2020 The installation dimensions for agricultural tractors and mechanical wheels on the hub
Basic Information
Scope
Main technical content: This standard specifies the dimensions for installing wheels on hubs when centering according to the center hole of the spokes, the conical surface of the spoke nut seat, and the spherical surface of the spoke nut seat on agricultural and forestry tractors and machinery wheels. It is recommended that the new-designed agricultural and forestry tractors and machinery wheels adopt the center hole of the spokes for installing dimensions on the hubs. This standard applies to agricultural and forestry tractors and disc-type wheels, but not to wheels mounted on front and rear drive axles equipped with gear reducers and corresponding mechanisms. The following installation dimensions do not mean that wheels can be interchanged between vehicles.
