Linear bearings, also called linear motion bearings or bushing, are mechanical devices designed to facilitate smooth, accessible, and controlled motion in a straight direction along a rail or track. These linear-motion bearings are must-have components of a linear guide assembly, offering smooth motion with precise accuracy. The primary function of a linear bearing is to support and guide the load while reducing friction. These components are made of robust materials, including steel, brass, bronze, ceramic, and graphite, ensuring long-lasting performance. In addition, linear bearings reduce wear and tear, providing the system’s longevity and minimising resistance, making them ideal for applications requiring linearly accurate movements.
