2. Contaminant Protection Grease seals act as a first line of defense against contaminants. Dust, water, and debris can enter the bearing assembly and potentially lead to corrosion, pitting, and other forms of wear. By keeping these contaminants out, grease seals help maintain the integrity of the bearings.

Heavy-duty serpentine belts are typically made from high-quality rubber compounds combined with reinforcing materials, such as polyester or Kevlar. This construction allows them to resist wear, tensile stress, and temperature extremes. The belts are designed with specific rib patterns on their surfaces to enhance grip on the pulleys and reduce slippage. The choice of materials and design features is what sets heavy-duty belts apart from standard belts, making them suitable for rigorous applications.

Moreover, flat timing belts are less prone to wear and fatigue
. The absence of teeth means there are fewer points of stress, reducing the likelihood of breakage or fraying over time. This translates to lower maintenance costs and longer service life, a crucial consideration for both automotive and industrial applications.
