Basic Concepts of Plain Washers

Plain washers are simple, flat, circular components used in mechanical systems to distribute load, reduce friction, and prevent damage to surfaces. They operate by providing a barrier between two surfaces that might otherwise rub against each other, leading to wear and tear. Commonly made from materials such as steel, stainless steel, brass, or nylon, plain washers are chosen based on the specific requirements of the application, including load-bearing capacity, corrosion resistance, and durability ².

Purpose of the 160514 Plain Washer

The Cummins 160514 Plain Washer is specifically designed to enhance the operation of commercial trucks. It contributes to the assembly by ensuring that components are securely fastened without direct metal-to-metal contact, which can lead to galling or seizing. This washer aids in the even distribution of loads across surfaces, reducing the risk of component failure due to uneven stress. Its role is vital in maintaining the integrity and efficiency of truck assemblies ³.

Key Features

The Cummins 160514 Plain Washer is characterized by its precise design and material composition. Typically made from high-quality steel or stainless steel, it offers durability and resistance to wear.
