Pneumatic discs are circular components used in various applications, primarily in braking systems. They operate by using compressed air to create friction, which slows down or stops a moving object. These discs are commonly found in vehicles, machinery, and industrial equipment, where reliable braking performance is essential. The design of pneumatic discs allows for efficient heat dissipation, reducing the risk of overheating during operation. They are often made from durable materials to withstand wear and tear. Proper maintenance of pneumatic discs is crucial for ensuring safety and optimal performance in systems like automobiles and heavy machinery.
