What is an oil-free bearing bushing? How to lubricate oil-free bearings?
Suitable for vertical use. Reduces the time of manufacturing and assembling the housing. Since Oil Free Bushings do not project from the bushing mounting position. According to the different frictional properties, bearings can be divided into sliding bearings and rolling bearings. There are various classification methods for sliding bearings according to the direction of load, the type of lubricant, the nature of the lubricating film, the structure of the bearing sleeve, the material of the bearing sleeve, etc. Among them, according to the different types of lubricants used in sliding bearings, can be divided into oil-lubricated bearings, grease-lubricated bearings, water-lubricated bearings, gas-lubricated bearings, solid-lubricated bearings, magnetic fluid bearings, and electromagnetic bearings.
The so-called oil-free bearings generally refer to sliding bearings, which belong to the category of sliding bearings. If oil-free bearings are defined by whether the lubricant is oil, water-lubricated, or air-lubricated, then electromagnetic can also be included in oil-free bearings. Today we only introduce this kind of bearing that uses self-lubricating material or oil-containing material, which is made by a special process and works without adding lubricant. It mainly refers to inlaid solid lubrication bearings and self-lubrication bearings.
Oil-free Bearing, plugged graphite, solid lubrication bearing
Oilless bushings are made from PTFE, copper alloy, carbon steel, polyacetal resin & bronze. Oilless bushings are available in various models, dimensions & sizes … China manufacturer of graphite plugged bearings made from C95400 aluminum bronze bushing and C8600 manganese bronze materials.

Bearings are resistant to corrosion and hostile environments. Suitable for viscous lubricants, oils, and grease applications. Serves the manufacturing, architectural, oil, gas, power generation plant, marine, and naval industries.
Take JDB Oil-free Bearing, plugged graphite series inlaid solid lubrication bearing as an example, it takes metal material as the substrate, on the substrate (brass, tin bronze, aluminum bronze, cast iron, GCr15 and other alloy materials) orderly arranged with suitable size holes, then embedded in oil graphite, PTFE, molybdenum disulfide particles as solid lubrication material. When the bearing works under oil-free lubrication condition, the solid lubricating material will be gradually transferred to the working surface of the friction sub due to the friction heat, thus reducing the friction coefficient.
Inlaid solid lubrication bearings are widely used in light industry, heavy industry, construction, metallurgy, transportation and other mechanical equipment, such as: continuous casting machine, rolling mill, injection molding machine, paper making machine, mold guide pillar, ship, machine tool, etc. Flanged Bushings – Metric Made of solid aluminum bronze with or without self-lubricating graphite.

Aluminium Bronze Oilless Bushes– a corrosion resistant metal in sea water
Finished Machined Aluminium Bronze Parts：Bronze corrosion in seawater， The maritime industry places high demands on its self-lubricating copper bushing materials. The high salt content of seawater and ocean currents are just two of the many factors that promote corrosion. However, there is an alloy that can withstand the harsh conditions of the ocean. Aluminum Bronze Bushing！Oil-free bushings, also known as self-lubricating bearings, are specially designed to reduce friction between moving parts without the need for oil-based lubrication. This is achieved through the incorporation of solid lubricants within the bearing material, which are gradually released as the bearing operates. The result is a component that requires less maintenance, lasts longer, and operates more efficiently than traditional bearings.

Oilless Bearings: The Future of Bearing Technology
As industries continue to evolve and innovate, so does the technology behind the machines that drive them. Bearings are an essential component of many industrial machines, providing support and reducing friction between moving parts. Traditional bearings rely on lubrication to reduce friction, but with advancements in material science, a new generation of bearings has emerged: oilless bearings.
What are Oilless Bearings?
Oilless bearings, also known as self-lubricating bearings, are a type of bearing that does not require external lubrication to operate smoothly. Instead, they are made of materials that inherently reduce friction, eliminating the need for additional lubrication. This makes them an ideal choice for machines that operate in harsh environments or where lubrication is difficult or impossible.
Benefits of Oilless Bearings
Oilless bearings offer several advantages over traditional lubricated bearings, including:
- Reduced Maintenance: Because oilless bearings do not require external lubrication, they require less maintenance than traditional bearings. This can save time and money over the lifespan of a machine.
- Longer Lifespan: Oilless bearings are designed to last longer than traditional bearings, reducing the frequency of replacements and associated downtime.
- Increased Durability: Oilless bearings are made of materials that are more durable than traditional bearing materials, allowing them to withstand higher loads and operate in harsher environments.
- Environmentally Friendly: Oilless bearings eliminate the need for external lubrication, reducing the amount of oil and grease that can leak into the environment.
Applications of Oilless Bearings
Oilless bearings are used in a wide range of industrial applications, including:
- Food and Beverage: Oilless bearings are commonly used in food and beverage processing equipment because they eliminate the risk of contamination from external lubricants.
- Medical Equipment: Oilless bearings are ideal for medical equipment because they are self-lubricating and reduce the risk of contamination.
- Aerospace: Oilless bearings are used in aerospace applications because they are lightweight and durable, making them ideal for high-performance applications.
- Marine: Oilless bearings are commonly used in marine applications because they can withstand harsh marine environments without the need for external lubrication.
Oilless bearings are a game-changing technology that offers numerous advantages over traditional lubricated bearings. Their inherent friction-reducing properties, combined with increased durability and reduced maintenance, make them an ideal choice for a wide range of industrial applications. As industries continue to evolve, it’s clear that oilless bearings will play a crucial role in shaping the future of bearing technology.
Bronze Sliding Bearing With Solid Lubricant Insert and Flange Bushing
Graphite is one of the three isomers of the chemical element carbon; the other two are diamond and amorphous carbon. Graphite crystallizes in a hexagonal system. Carbon atoms are tightly bound together in the form of flakes. Due to the weak bonding between the flakes, graphite shows a low shear strength under friction. Therefore, it can be used as a solid lubricant and has become one of the traditional and main solid lubricating materials.

Sliding Partners for Oilless Bushes and Plates
The most compatible sliding partners for Oilless Bushes and Plates are gas-nitrated or hardened steel alloys with a hardness greater than 35 HRC. To achieve optimal sliding behavior, it is crucial that the hardness difference between the bush or plate and the sliding partner is at least 100 HB. Additionally, the surface roughness of the sliding partner should be maintained between Rz = 3 to 6.3 µm, achieved through grinding.
