One of the primary factors influencing the price of oil seals is the cost of raw materials. Oil seals are typically made from a combination of rubber, plastics, and metals, all of which have their own price volatility. For instance, the cost of synthetic rubber can change dramatically based on the price of crude oil, as it is a petroleum-based product. When oil prices rise, manufacturers may face higher production costs, which they often pass on to consumers. Furthermore, geopolitical tensions or natural disasters can disrupt the supply chain, leading to increased raw material costs and, subsequently, higher oil seal prices.
Brake drum wear typically results from several factors. Primarily, the friction generated between the brake shoes and the drum during the braking process leads to material degradation. This friction produces heat, which can cause the drum to warp or crack if the temperatures exceed certain thresholds. Additionally, heavy braking or aggressive driving habits can accelerate wear, as can poorly maintained braking systems that may cause uneven wear patterns. Contaminants like dirt, moisture, or oil can also contribute to premature brake drum wear, affecting performance and safety.
