The V-belt B60, specifically, is a section of the A-type belt, typically characterized by its width and the exact dimensions that make it suitable for various pulleys. The “B” indicates the belt width, which is approximately 17mm, while “60” signifies the belt's length, measured in inches. One of the primary attributes of the B60 is its construction from durable materials, often a combination of rubber and fabric, which provides excellent flexibility and wear resistance.

The most common material used in timing belts is various types of rubber. Synthetic rubber, such as neoprene, is often preferred due to its superior resistance to heat and wear compared to natural rubber. The rubber provides flexibility, allowing the belt to bend around pulleys without cracking. This elasticity also contributes to a quiet operation, reducing engine noise. However, rubber's susceptibility to degradation from oil, heat, and ozone exposure necessitates the incorporation of additives and reinforcements.
