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.

FAQs
Q1: Can non-metallic bearings handle heavy loads?
A1: These bearings are best suited for medium to low loads. For higher loads, fiber-reinforced composites are recommended.
Q2: Do they require external lubrication?
A2: No, they are self-lubricating and operate without additional lubricants.
Q3: Are they suitable for high-temperature environments?
A3: Material choice determines the temperature range. For instance, PTFE can handle up to 250°C, while POM is limited to lower ranges.
Q4: Are these bearings safe for food processing applications?
A4: Yes, many non-metallic materials meet food-grade standards and are ideal for such applications.
Q5: Can custom dimensions or designs be manufactured?
A5: Yes, non-metallic bearings can be tailored to fit specific equipment needs.
Summary
Non-metallic boundary lubrication bearings are efficient, environmentally friendly, and maintenance-free. They excel in automotive, industrial, medical, and food processing industries due to their self-lubrication, lightweight construction, corrosion resistance, and quiet operation.
Although they may not be optimal for extreme loads or high-speed conditions, innovations in material and structural design allow them to cater to a wide range of industrial requirements. Selecting the right bearing based on operational conditions, such as load, speed, and temperature, ensures optimal performance and longevity of the equipment.
