Solutions for your SELF-LUBRICATING BEARING business

Oilless Bearing - Long-term Wear Resistance

Oilless bearing is a kind of novel lubricating bearing that has the characteristics of metal bearing and oil-free lubricating bearing, the load is borne by the metal matrix, and the specially formulated solid lubricating material plays the role of lubrication. It has a high bearing capacity, impact resistance, high-temperature resistance, self-lubricating ability, etc.The oilless bearing is especially suitable for heavy load, low speed, reciprocating or oscillating, and other difficult to lubricate and form oil film occasions, and is not afraid of water and other acid corrosion and scouring.

Enhancing Efficiency and Reliability: Exploring the World of Self-Lubricating Bearings and Related Products

In the realm of industrial machinery and equipment, the efficiency and longevity of moving parts play a crucial role.

Self-lubricating bearings and related products have revolutionized the industrial sector by providing reliable, maintenance-friendly, and environmentally conscious solutions. The elimination of external lubricants and the utilization of innovative materials have enhanced the efficiency, reliability, and longevity of moving parts in machinery and equipment. When selecting self-lubricating bearings, considering maintenance requirements, specific features, materials, and related products like die components ensures optimal performance. By embracing these advancements, industries can significantly reduce maintenance costs, improve productivity, and contribute to a greener future.

Maintenance of Self-Lubricating Bearings:

One of the key advantages of self-lubricating bearings is their minimal maintenance requirements. Unlike traditional bearings that rely on external lubricants, self-lubricating bearings are designed with built-in lubrication systems. These systems often employ solid lubricants, such as graphite or PTFE (polytetrafluoroethylene), which are embedded within the bearing material. As a result, the need for frequent re-lubrication is eliminated, reducing downtime and maintenance costs. However, it is important to periodically inspect self-lubricating bearings to ensure proper functioning and replace them when necessary.


When selecting a self-lubricating bearing, it is crucial to consider its specific features in order to meet the unique requirements of your application. Self-lubricating bearings come in a variety of designs, including sleeve bearings, flanged bearings, and thrust bearings. Factors such as load capacity, rotational speed, temperature resistance, and environmental conditions should be taken into account. For high-load applications, composite bearings with reinforced materials may be preferred, while applications requiring high-speed rotation might benefit from bearings with low friction coefficients.

Selecting the Oilless Bearing by Material:

Self-lubricating bearings are available in various materials, each with its own set of properties and applications. Popular materials used for oil-free bearings include bronze, steel, and composites. Bronze bearings are widely used due to their excellent load capacity and wear resistance. Steel bearings offer exceptional strength and durability, making them suitable for heavy-duty applications. Composites, on the other hand, provide a combination of properties, such as low friction, corrosion resistance, and self-lubrication. Careful consideration of the material's characteristics and compatibility with the operating conditions is essential for optimal bearing performance.

Related Products: Die Components:

In addition to self-lubricating bearings, there are other related products that contribute to efficient machinery operation. One such product category is die components. Dies are widely used in various manufacturing processes, including metal stamping, extrusion, and forging. Self-lubricating die components, such as bushings, wear plates, and guide posts, offer reduced friction, improved wear resistance, and extended tool life. These components are often made from self-lubricating materials, ensuring smooth operation, reduced downtime, and enhanced productivity.

Solid Self-Lubricating Bearing, at high force brass substrate. Mosaic graphite or MoS2 solid lubricant is a high-performance solid lubricant. It broke through the general bearing lubrication film to rely on limitations. During use, heat through friction with the shaft friction of solid lubrication, forming oil, lubrication powder coexist excellent condition, both to protect the shaft is not worn, and the solid lubricant properties eternal. Its hardness copper sleeve than twice as high wear resistance is also twice as high.

The product has been used in metallurgy continuous casting machine, the train bracket, rolling equipment, mining machinery, shipbuilding.
