One of the key factors contributing to the popularity of flat leather drive belts is their relatively low maintenance requirements compared to other types of belts. With proper care, leather belts can last for many years, providing an economical solution for businesses. Regular maintenance practices include periodic inspections for signs of wear, lubrication to reduce friction, and conditioning treatments to keep the leather supple. Unlike synthetic materials, leather has a natural resilience, allowing it to withstand the rigors of daily use without failing prematurely.

Timing belts are typically composed of a combination of rubber and reinforced fibers. The rubber used in timing belts is often synthetic, designed to withstand extreme conditions including heat, oil, and wear. The most common types of rubber used in timing belts are neoprene and ethylene propylene diene monomer (EPDM). These materials are known for their durability and flexibility, allowing the belt to handle the tension and stress during engine operation.
