1. Agricultural cast iron wheel is made of high-quality steel (carbon steel or alloy steel) and has wear resistance. 2. The V-groove of agricultural cast iron wheel is processed by high-precision CNC machine tools to ensure that it matches the profile of the v-belt perfectly, effectively preventing the belt from slipping and improving transmission efficiency. 3. Agricultural cast iron wheel with single groove, multi-groove, different diameters and widths is available to meet different torque, speed ratio and power transmission requirements.
