Bronze Oilless Bushes Oilless Bearings Self-lubricating Bearings
Oil or grease lubrication is sometimes necessary for specific applications. To minimize maintenance, VIIPLUS designs lubrication grooves in their bronze bushings to efficiently distribute lubrication throughout the bearing.
Solid turned bronze bushings can be either heavy-maintenance or maintenance-free, depending on the application and the material used. Here is a table chart of standard materials and additional alloys for bronze bushings:
| Material | Alloy |
|---|---|
| CuZn25Al5Mn4Fe3 | Standard Material |
| CuSn7ZnPb (RG7) | Additional Alloy |
| CuSn10 | Additional Alloy |
| CuSn12 | Additional Alloy |
| CuPb10Sn10 | Additional Alloy |
| CuZn25Al5Mn4Fe3 | Additional Alloy |
| CuSn5ZnPb (RG 5) | Additional Alloy |
These bushings are made with wear-resistant metal bronze material as the base, and by adding various lubricating materials, the friction coefficient is reduced, and self-lubrication is achieved. This combination of materials offers the advantages of high load-bearing capacity from metal and the low friction coefficient from non-metal, allowing the bushings to be used in various working conditions.
Solid lubricating bearings can be categorized into two types based on the distribution of solid lubricant:
- Mosaic solid lubrication bearings: These bearings have solid lubricant particles arranged in a specific proportion and pattern within the working layer. They are suitable for low-speed and high-load applications.
- Dispersive solid lubricated bearings: These bearings have solid lubricant particles uniformly distributed throughout the working layer. They can maintain a very low coefficient of friction even at high speeds and under microscopic conditions.
By selecting the appropriate bronze bushing material and incorporating well-designed lubrication grooves, VIIPLUS ensures that their bearings provide reliable performance and a long service life under various operating conditions.
Standard Dimensions For Lubrication Grooves, Design of lubrication hole and grooves
Designing lubrication holes and grooves in oilless bronze bearings is essential for ensuring proper distribution and retention of the lubricant within the bearing. To achieve optimal performance, it is important to follow standard dimensions and guidelines for the design of these features.
Here is a chart table of the recommended dimensions for lubrication grooves in oilless bronze bearings:
| Parameter | Recommendation |
|---|---|
| Length of lubrication groove | 70-80% of bearing width |
| Edges of lubrication groove | Rounded |
| Location of lubrication hole | Inside the lubrication groove |
| Outer diameter (OD) groove | Add a groove on the OD for lubricant fed from housing |
Types of self-lubricating bronze bearings grooves:
There are several types of grooves or plugged graphite designs that can be used based on the specific lubricant and movement requirements of the bearing. These grooves can be either closed or open on one or both sides.
- Straight grooves: Simple, linear grooves that run along the bearing’s surface. These grooves are effective for distributing lubricant in applications with linear movement or rotation.
- Circular grooves: Curved grooves that follow the circumference of the bearing. These grooves are suitable for rotational applications and provide consistent lubrication across the entire bearing surface.
- Helical grooves: Spiral-shaped grooves that twist around the bearing. These grooves are useful for applications with complex movement patterns and can help to evenly distribute lubricant across the bearing’s surface.
- Radial grooves: Grooves that extend outward from the center of the bearing. These grooves are ideal for distributing lubricant in applications with oscillating or pivoting movements.
- Custom grooves: In certain cases, custom groove designs may be necessary to accommodate unique lubrication requirements or specific application conditions.
By following these guidelines and recommendations for the design of lubrication holes and grooves in oilless bronze bearings, you can ensure optimal lubricant distribution and retention, ultimately recognized to improved bearing performance and longevity.
Graphite-plugged bronze bushings, in particular, are highly suited for these types of applications.
Some of the notable benefits of using graphite bushings and bearings include:
- Self-lubricating properties: Graphite bushings provide a self-lubricating system, eliminating the need for external lubricants or maintenance. This makes them ideal for applications where traditional lubrication methods are challenging or not feasible.
- High load-bearing capacity: Graphite bushings can support heavy loads, making them suitable for use in heavy machinery and industrial equipment.
- High-temperature resistance: Graphite bushings can operate effectively at elevated temperatures, making them an excellent choice for high-temperature applications, such as in furnaces, kilns, or engine components.
- Corrosion resistance: Graphite bushings are highly resistant to corrosion, ensuring a longer service life in applications where they may be exposed to water or other corrosive substances.
- Low friction: The solid lubricant in graphite bushings results in reduced friction between mating components, which can improve the efficiency of the system and decrease wear on the parts.
Oilless bushings, also known as self-lubricating bronze bearings, are designed to function with little to no added lubrication. The primary objective of this type of bearing is to ensure that it performs well under conditions where external lubrication is minimal or absent and to maximize its service life as much as possible.
The basic working principle of a self-lubricating bearing involves the formation of a transfer film on the bearing surface during the initial stages of operation. This transfer film is created due to the friction between the solid lubricant on the bearing surface and the mating component. As the bearing continues to operate, a solid lubrication film forms on the contact surfaces, which effectively separates the workpiece from the bearing, preventing direct contact.
This process of forming a solid lubrication film on the interacting surfaces achieves the desired self-lubrication and offers several benefits:
- Reduced maintenance: Self-lubricating bearings require little to no additional lubrication, which minimizes maintenance efforts and associated costs.
- Extended service life: The solid lubrication film protects the bearing and the workpiece, preventing direct contact and reducing wear, which ultimately results in a longer service life for both components.
- Environmentally friendly: The use of self-lubricating bearings reduces the need for oil and other external lubricants, minimizing potential environmental impact.
- Improved efficiency: The solid lubrication film reduces friction between the bearing and the workpiece, improving the overall efficiency of the system and decreasing energy consumption.
- Versatile applications: Self-lubricating bearings can be utilized in various industries and applications where external lubrication is challenging, impractical, or undesirable.
In conclusion, oilless bushings or self-lubricating bronze bearings are designed to provide effective lubrication with minimal reliance on external lubricants. By forming a solid lubrication film on the contact surfaces, these bearings can extend the service life of both the bearing and the workpiece while offering numerous benefits, such as reduced maintenance, improved efficiency, and environmental sustainability.
This CAPTION provides essential guidelines for the design, assembly, and maintenance of bronze bushing bearings and related components. Below is a detailed explanation of each point for clarity and practical application:
1. Use Standard Specifications in Design
- Purpose: Standardization ensures compatibility, reduces costs, and simplifies procurement and replacement.
- Action: Refer to industry standards (e.g., ISO, DIN, or ASTM) for dimensions, tolerances, and material specifications.
2. Check for Foreign Bodies During Assembly
- Purpose: Foreign particles (dust, debris, etc.) can cause wear, misalignment, or damage to the bearing surface.
- Action: Clean the assembly area, components, and tools thoroughly before installation. Inspect surfaces for contaminants.
3. Black/Gray-Black Oil Film on Sliding Surfaces
- Purpose: The black or gray-black film is a solid lubricant (e.g., graphite or molybdenum disulfide) that forms during operation and reduces friction.
- Action: Do not scrub or remove this film. It is a normal and beneficial byproduct of the lubrication process.
4. Apply Lubricating Oil Before Assembly
- Purpose: Pre-lubrication reduces initial friction and wear during the “running-in” period.
- Action: Apply a suitable lubricant to the sliding surfaces and grinding parts before assembly to ensure smooth operation.
5. Press in Slowly During Assembly

A high-strength copper alloy brass bushing
GRAPHITE SLEEVES
A high-strength copper alloy is used as the base material, and holes are machined in its working surface and filled with solid lubricant in a certain ratio according to the conditions of use. The high-strength copper alloy provides a high load-bearing capacity, while the solid lubricant creates a low friction. Under dry friction conditions we pre-design a lubricating film on the bearing surface to ensure that the solid lubricant is transferred to the coupling and an effective solid lubricant film is formed in the shortest possible time.
Graphite sleeves are a type of high-strength copper alloy brass bushing that are designed for use in applications requiring low friction and high load-bearing capacity. The base material for these sleeves is a high-strength copper alloy, which is known for its excellent mechanical properties, corrosion resistance, and heat conductivity.
In order to achieve low friction, holes are precision machined into the working surface of the copper alloy bushing. These holes are then filled with a solid lubricant, typically graphite, in a specific ratio based on the intended operating conditions. This combination of materials allows for an effective, long-lasting lubrication system that functions well even under dry friction conditions.
The pre-design of a lubricating film on the bearing surface ensures that the solid lubricant is quickly transferred to the mating components during initial operation. This helps to establish an effective solid lubricant film in the shortest possible time, reducing wear and the risk of damage to both the graphite sleeve and the coupled component.
Graphite sleeves are commonly used in a variety of industries and applications, including automotive, aerospace, heavy machinery, and industrial equipment. Their unique combination of high load-bearing capacity, low friction, and self-lubricating properties make them an ideal choice for applications where traditional lubrication methods may be inadequate or impractical.

2. No oil can be used;
Since solid lubricant is greater than the linear expansion coefficient of the metal matrix, so when running solid self-lubricating bearings, the oil film will be transferred to the grinding and implemented on a self-lubrication, so solid self-lubricating bearings can be used in the place where is hard to go and can’t go or grease, even in the case of low speed and high load also can have good lubrication effect.
3. Low use cost;
The traditional mechanical design, in a certain operating time, wants to often come on maintenance, check the oil, the oil supply device was clear, the body itself and the surrounding environment pollution caused by regular gas, result in an increase in maintenance costs, realize self-lubrication, not only can realize the environment clean and tidy, and greatly reduce the cost of the use of lubricating oil.
4. Under the condition of high load and low rotating speed, it can give play to superior performance;
Solid self-lubricating bearing is made of centrifugal casting high strength alloy brass substrate, have the effect of bearing load, with special formula with good self-lubricating properties of graphite lubricant, self-lubricating effect, so it’s a combination of their respective advantages, even in high load, low speed, can produce superior performance.
5. Excellent wear resistance can be developed in places where the oil film is difficult to form, such as reciprocating motion, rocking motion, and frequent starting and stopping;
The arrangement principle of solid self-lubricating bearing lubricants is to ensure that there are lubricants in each part of the grinding part in the process of operation, so the arrangement of lubricants must be determined according to the direction of the movement of the grinding part.
6. The bushing bearings cost is more competitive, compared with similar products, the service life is longer, the maintenance is less, the replacement cycle is long, and the performance is good.
Solid bronze bearings are mounted on a matrix of colliers brass. A high performance solid lubricant with graphite or MoS2 solid lubricants. It breaks through the general bearing lubrication by oil film limitations. In the process of use, through the friction heat to make the solid lubrication and shaft friction, the formation of oil, powder co-lubrication excellent conditions, not only protect the shaft from wear, and make the solid lubrication characteristics eternal. Its hardness is higher than average copper sleeve one times, wear-resisting property is also one times. At present, the product has been used in metallurgical continuous casting machines, train support, steel rolling equipment, mining machinery, ships, gas turbines and other high temperature, high load, low speed heavy load and other occasions.
1. Flexible design, simple and convenient, wide range of use.
Oil supply system in the mechanical design is a large workload, time-consuming device, the use of solid self-lubricating bearings do not need to consider in the design of oil-saving means, and can be for a variety of special occasions, the solid self-lubricating bearings designed into a variety of shapes to meet the needs of a variety of special occasions, the use of solid self-lubricating bearings, can greatly reduce the cost of mechanical maintenance, fuel, etc.
2. 2. can be used without oil.
Because the linear expansion coefficient of solid lubricant is greater than the linear expansion coefficient from the metal matrix, so when the solid self-lubricating bearing starts to run, the oil film will be transferred to the grinding parts to achieve self-lubrication, so the solid self-lubricating bearing can be used in the place where it is difficult to refuel and can not refuel or grease, even in the case of low speed and high load, it can also play a good role in lubrication.
3. 3. Low cost of use.
Traditional mechanical design, in a certain operating time, refueling and maintenance to frequently check the oil table, oil tank is clear, due to frequent refueling of the body itself caused by pollution, resulting in increased maintenance costs, the realization of self-lubrication, not only can make the environment clean, but also can greatly reduce the use of lubricant costs.
