- Description
- The product is a precision-machined aerospace component described as a reaction plate for a torque brake assembly. It is made from 15-5PH precipitation hardening stainless steel, conforming to AMS 5659 Type 1 material specification. The component is manufactured as a solid cylindrical (round-section) part with a controlled length of 1397 mm to 1409 mm (±2 mm) and a diameter of approximately 38.1 mm to 38.35 mm. It is specifically designed for use within a trailing edge transmission actuator on a Boeing 737 aircraft and is manufactured to a Boeing design drawing. Additional physical description: The component is manufactured as a solid cylindrical (round-section) part with a controlled length of 1397 mm to 1409 mm (±2 mm) and a diameter of approximately 38.1 mm to 38.35 mm. It is not a general-purpose bar or rod, but a finished, function-specific aerospace component produced exclusively for the stated aircraft application. The component is used within an aircraft trailing edge transmission actuator system, where it forms part of a torque brake mechanism. It functions to control, transfer, and resist mechanical torque, contributing to the safe operation of aircraft control surfaces. The reaction plate acts as a load-bearing, torque-reacting component within the brake assembly. It absorbs and transfers torque forces generated during actuator operation, helping regulate movement and maintain correct positioning of aircraft components. The component is fully machined to precise dimensional tolerances, heat treated to achieve a strength range of approximately 180–200 ksi in accordance with Boeing specifications, and deburred and finished to remove sharp edges. The component is supplied as a single finished machined metal part.
