B-Type, C-Type, D-Type Belt Pulley

In the production process, belt pulleys are typically manufactured using casting methods. The choice of material depends largely on the size of the pulley. For larger belt pulleys, cast steel is often used, whereas smaller ones are usually made from cast iron. Cast iron is generally preferred for smaller pulleys because it offers better overall performance in terms of casting quality and mechanical properties. In contrast, cast steel is rarely employed for belt pulley production, primarily due to the poor casting characteristics of steel, which make it less suitable for forming complex pulley shapes with high precision and reliability.

Belt pulleys find extensive application across a wide range of industrial machinery. They are commonly used in mining machinery, mechanical processing equipment, textile machinery, packaging machinery, and various types of agricultural machinery for power transmission purposes. In addition, belt pulleys are also integral components in air compressors, speed reducers, gearboxes, generators, and cotton ginning machines, among many other mechanical systems.
