What types of solid self-lubricating bearings include?

Solid self-lubricating bearings

Solid self-lubricating bearings include oil-free self-lubricating bearings, embedded solid lubricating bearings, multi-layer composite solid-lubricating bearings and other types. As a type of sliding bearing, solid lubricant bearings use solid lubricants instead of traditional grease lubricants and have the characteristics of stability, pressure resistance, wear resistance and high temperature resistance. The following is an introduction to the types of solid self-lubricating bearings:

Oil-free self-lubricating bearings
Basic concept: Oil-free self-lubricating bearings are bearings that can achieve self-lubricating function without the need for external lubricating oil or grease. This type of bearing uses the characteristics of its own material to form a lubricating film on the friction surface, thereby reducing the friction coefficient and reducing wear.
Product series: Zhejiang Mingxu Machinery Manufacturing Co., Ltd. produces a wide range of oil-free self-lubricating bearings, including SF-1 series oil-free lubricating bearings, DU bushings, JF series bimetal bearings, etc. These products are widely used in automobiles, molds, plastic machinery and other fields, and can significantly improve the performance and life of equipment.
Application advantages: Since no external lubricating oil is required, this type of bearing can simplify equipment design and reduce maintenance costs. At the same time, it can still maintain stable lubrication performance under harsh environments such as high load and high temperature.

Inlaid solid lubricated bearings
Structural features: Inlaid solid lubricated bearings are inlaid with solid lubricants, such as graphite, molybdenum disulfide, etc., on a metal substrate. These solid lubricants are used to achieve friction reduction and anti-wear effects.
Product Type: Zhejiang Mingxu Machinery Manufacturing Co., Ltd. provides a variety of inlaid solid lubricating bearings, such as JDB/JFB series inlaid solid lubricating bearings. These bearings are often used in scenarios where heavy loads, low speeds and long-term stable operation are required.
Working principle: In the initial operation stage, the solid lubricant forms a transfer film due to friction and adheres to the wear parts. Finally, a solid lubricating film is formed to achieve self-lubrication and protect the wear parts.

Multi-layer composite solid self-lubricating bearings
Composition and function: Multi-layer composite solid self-lubricating bearings are composed of multiple layers of different materials. Each layer has different functions. For example, the base layer is responsible for bearing and maintaining shape, the middle layer enhances bonding strength and heat dissipation, and the inner layer is solid lubricated. Material.
Application scenarios: This kind of bearing is suitable for applications that require high load-bearing capacity and good heat dissipation conditions, such as rotating parts in heavy machinery and high-precision equipment.
Comprehensive advantages: Multi-layer composite solid self-lubricating bearings combine the advantages of multiple materials and can provide stable lubrication performance and long service life under complex working conditions.

Integral solid self-lubricating bearing
Material characteristics: Integral solid self-lubricating bearings are made of materials with self-lubricating properties, such as polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK) and polyoxymethylene (POM). These materials themselves have good lubrication properties and certain load-bearing capacity.
Advantages of use: Integral solid-lubricated bearings have good corrosion resistance, can maintain performance without degradation in extreme environments, and do not require additional oil supply devices, reducing the time and cost of equipment downtime and maintenance.
Industry application: Widely used in light industrial machinery, office equipment, sports equipment and other fields, especially suitable for occasions that require frequent rotation or swing.

In addition to the above analysis, here are some notes:
Choose the appropriate type: Choose the appropriate solid self-lubricating bearing type according to the load, speed, temperature and other conditions of the specific application.
Installation and maintenance: Strictly follow the installation instructions provided by the manufacturer, regularly check the working status of the bearings, and replace seriously worn parts in a timely manner.
Compatibility test: If it needs to be mixed with other lubrication methods, it should be ensured that the newly selected solid self-lubricating bearing is compatible with the existing lubricating grease.
Environmental considerations: Give priority to products that meet environmental standards to reduce the environmental burden caused by waste oil treatment.

In summary, solid self-lubricating bearings are an efficient and long-life sliding bearing solution. Their diverse product lines and wide range of applications make them an indispensable component in the design of modern industrial equipment. Reasonable selection and use of solid-lubricated bearings can not only optimize equipment performance, but also significantly reduce maintenance costs and environmental impact.
