McFarlane MS20220-2 Pulley is an aircraft flight control system pulley designed to provide smooth and reliable cable routing within mechanical control systems. This precision pulley is used to guide control cables while reducing friction and maintaining proper cable alignment throughout the aircraft control system.

The MS20220-2 features a durable phenolic pulley body with an integrated ball bearing assembly, providing low-friction rotation and dependable operation under aircraft service conditions. The bearing-supported design helps minimize cable wear, improves control system efficiency, and supports consistent movement of primary and secondary flight controls.

This pulley is commonly installed in aircraft flight control cable systems for routing and direction changes of control cables. It is designed for use with compatible aircraft cable sizes and provides reliable mechanical performance in applications where precise cable movement, reduced friction, and long service life are required.

Regular inspection should include checking pulley rotation, bearing condition, groove wear, cable tracking, and attachment security. Replacement of worn or damaged pulleys helps maintain proper flight control system operation and supports continued aircraft airworthiness.
