The Swing Brake Inner Disc generates controlled friction inside the brake assembly to slow down and stop swing rotation when braking force is applied. The disc allows smooth deceleration by converting rotational energy into frictional resistance, helping maintain stable positioning during operation. By controlling swing speed and holding the upper structure in place, the disc supports safe directional changes and accurate movement control, and ensures balanced stopping action and steady equipment handling.Attributes:• Maintains steady holding torque when swing motion is stopped.• Reduces uncontrolled rotation during idle conditions.• Supports smooth deceleration of rotating structures.Applications: The Swing Brake Inner Disc is located inside the swing brake assembly within the upper structure rotation system and works within this braking area to control and stop rotational movement when braking force is applied.
