Overview of Non-Metallic Boundary Lubrication Bearings<\/h2>\n

Non-metallic boundary lubrication bearings<\/strong> are made from polymer materials (such as PTFE, POM, or PA) or composite materials. These bearings rely on the inherent low friction and wear-resistant properties of their materials to function effectively under boundary lubrication or dry friction conditions. They are widely favored in applications requiring lightweight designs, low maintenance, or corrosion resistance.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n
