Pivot Bracket: Load Capacity 500-2000 N, Bore Diameter 12-25 mm

Component Specifications

Definition

The pivot bracket is a precision-engineered mounting component designed to facilitate controlled rotational movement of dancer arms in tension control systems. It serves as the fulcrum point, allowing the dancer arm to pivot smoothly while maintaining structural integrity under dynamic loads. This component ensures proper alignment, reduces friction, and distributes stress evenly across the assembly.

Working Principle

The pivot bracket operates on the principle of rotational kinematics, providing a fixed axis of rotation for the dancer arm. It converts linear motion from material tension into controlled angular displacement, maintaining consistent tension through mechanical leverage and bearing surfaces.

Materials

Typically manufactured from high-strength steel alloys (e.g., AISI 4140 or 4340) or aluminum alloys (e.g., 6061-T6) for lightweight applications. Surface treatments may include zinc plating, powder coating, or anodizing for corrosion resistance.
