Fangrui Product Details 1) The Integrated Shaft Design Ensures Better Concentricity Of The Gears, Reduces Eccentric Rotation Of The Gears Due To Assembly, And Ensures That The Gears Transport Filament More Evenly. 2) Cnc Hollow Pom Gear, Reduction Gear Design, High Transmission Ratio, Achieving Greater Extrusion Torque 3) The Driven Gear Uses Double Ball Bearings Instead Of The Old Needle Bearings, With Smaller Clearance And Higher Precision. 4) Use High-strength Mold Steel As The Material Of The Feeding Gear, And Use Nano-coating For Treatment. The Overall Hardness Hrc Value Of The Gear Reaches 62-65; The Hardness Hv Value Reaches 1000-1200, Which Greatly Ensures The Gear Strength, Wear Resistance And Resistance. 5) Helical Gear Design, Better Meshing Performance, Smoother Gear Transmission, And More Linear Transmission Force. The Transmission Overlap Is Large, The Meshing Time Is Long, And The Contact Area Is Large, Which Reduces The Stress, Thereby Improving The Load-bearing Capacity Of The Gear And Extending The Service Lif
