One of the key advantages of EPDM PK belts, compared to traditional rubber belts, is their ability to withstand a wider range of temperatures. This quality ensures that they maintain their flexibility and strength, even in harsh operating environments. Furthermore, EPDM PK belts exhibit excellent resistance to abrasion and aging, making them suitable for heavy-duty applications.

The timing belt's primary function is to maintain the precise timing of engine operations. In a typical four-stroke engine, the sequence includes intake, compression, power, and exhaust strokes. If the timing belt fails or slips, it can lead to an out-of-sync engine, resulting in poor performance, increased emissions, and potentially catastrophic engine damage—often referred to as a timing belt failure.

2. HVAC Systems Heating, ventilation, and air conditioning systems often rely on EPDM PK belts to drive fans and other components. The resistance to temperature fluctuations and ozone exposure contributes to the reliability of these systems.

In an internal combustion engine, the tooth v belt connects the crankshaft to the camshaft. As the crankshaft rotates, it drives the belt, which in turn rotates the camshaft. This synchronization is crucial because it ensures that the engine's valves open and close at the correct times during the intake and exhaust strokes, optimizing the engine's efficiency and power output.

Pulleys are wheel-like components that guide and support the V-belt. They come in various designs, including flat, v-grooved, and crowned styles, often mounted on shafts. Pulleys convert rotary motion from one shaft to another while maintaining tension in the V-belt. The size and design of the pulley directly affect the speed and torque transmitted through the belt.

Another vital factor is market demand. In recent years, the sewing machine industry has seen an increase in demand driven by trends like sewing for personal use, sustainable fashion, and homemade crafts. A surge in demand for sewing machines consequently increases the demand for spare parts, including V-belts. This demand can lead to price inflation, particularly if the supply chain is disrupted or if raw material costs increase.

4. Noise Reduction Due to their design, poly V belts are generally quieter than conventional V-belts. This attribute is particularly beneficial in applications where noise pollution is a concern.
