Spacers, typically small components, are designed to maintain specific distances between objects. Their appearance varies widely based on application and material. They can present as simple flat washers, cylindrical sleeves, or more complex geometric forms. For instance, a spacer used in a machine might resemble a metal ring, while a spacer in a circuit board could be a small plastic standoff.
The use of these components is essential for proper alignment, preventing friction, and ensuring structural integrity across diverse industries. Historically, spacers have played a critical role in manufacturing and construction, contributing to the stability and longevity of assemblies. Their precise dimensions directly impact the performance and safety of the final product.
