Non-Metallic Boundary Lubrication Bearings
Non-metallic boundary lubricated bearings are a type of bearing made of polymer materials or composite materials. Relying on the self-lubricating properties of the material, it achieves low friction, wear-resistant and efficient operation without the need for additional lubricants, and is particularly suitable for medium and low load conditions and harsh environment applications.
Advantages
Maintenance-free: Reduces lubrication maintenance requirements and reduces operating costs.
Environmentally friendly: Oil-free operation reduces pollution; recyclable materials are more sustainable.
High adaptability: Suitable for industries with high requirements for cleanliness and hygiene, such as food processing and medical equipment.
Economical and practical: Relatively low production costs, long service life, and high overall cost-effectiveness.
Overview of Non-Metallic Boundary Lubrication Bearings
Non-metallic boundary lubrication bearings 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.
