PU (Polyurethane) lubricated gears are high-performance transmission components integrating the toughness of PU with excellent lubricity. They boast outstanding wear resistance, reducing friction between gear teeth effectively, thus extending service life and lowering noise during operation.
With good elasticity and impact resistance, these gears adapt well to light and medium-load applications, avoiding rigid collisions. They are widely used in household appliances, office equipment, small machinery and automotive accessories due to their corrosion resistance and stable transmission efficiency. The integrated lubrication design simplifies maintenance, making them cost-effective and reliable choices for daily transmission systems.
