Washers & strips


Washers and strips, also known as flat plain bearings, are fundamental mechanical components designed to minimize friction and wear between moving parts. Unlike ball or roller bearings, flat plain bearings have a simple, flat, and often rectangular or circular design. They are usually made of low-friction materials such as bronze, brass, or composite materials and in some cases require lubrication to operate efficiently.

Types of washers and strips

Rectangular Flat Plain Bearings: These flat plain bearings feature a rectangular shape and are often used in linear motion systems. They are designed for applications where stability and precision are essential.

Circular Flat Plain Bearings: Circular flat plain bearings are often employed in rotating machinery to reduce friction and distribute loads evenly. They come in various sizes and materials to suit specific applications.


The Role of washers and strips

Friction Reduction

The primary function of flat plain bearings is to reduce friction between moving parts. They achieve this by providing a low-friction interface between components, allowing them to glide smoothly and efficiently.

Load Distribution

Flat plain bearings play a pivotal role in distributing loads evenly across moving parts, preventing localized stress and wear. This even distribution is vital for extending the lifespan of machinery and ensuring its reliable operation.

Noise Reduction

The low-friction properties of flat plain bearings contribute to noise reduction in machinery, creating quieter and more efficient systems.


Applications of washers and strips
