The 481-612 is a Piper OEM aircraft control cable pulley used to guide and redirect flight control cables within the aircraft structure. It provides a smooth, low-friction routing path that allows control cables to change direction while maintaining correct tension and alignment.

In Piper aircraft applications, pulleys such as the 481-612 are used in primary flight control systems (ailerons, elevators, rudder) as well as secondary systems like trim or flap controls, depending on aircraft model configuration. Its role is to ensure that control cable routing follows the designed airframe path without binding, excessive friction, or wear.

The pulley wheel rotates on a precision bearing or bushing assembly mounted within a bracket, allowing consistent movement under load. This design minimizes cable abrasion and ensures reliable transmission of pilot input to the control surfaces.

Manufactured to Piper OEM specifications, the 481-612 is typically made from aircraft-grade aluminum alloy or steel, with a precision-machined groove sized for standard aviation control cables. The bearing system is engineered for durability, low friction, and resistance to vibration and cyclic loading.

Because it is part of the flight control system, proper condition is essential. Wear in the pulley groove, bearing roughness, or misalignment can increase friction and negatively affect control feel and system efficiency.
