Bronze bearings are an essential component of many industrial and mechanical systems. They are made from a mixture of copper, tin, and sometimes other elements, and provide a low-friction surface for rotating or sliding parts. However, the performance of a bronze bearing is heavily influenced by its groove type, which determines how lubrication is distributed throughout the bearing surface.

There are several different types of bronze bearing groove patterns, each with their own advantages and disadvantages. The most common groove types are circular, straight, single loop, double loop, straight and circular, figure 8, and double figure 8.

Circular Groove Type:

The circular groove type is a basic and straightforward pattern consisting of a series of concentric circles on the bearing surface. The purpose of this groove type is to distribute lubrication evenly across the surface of the bearing, reducing friction and wear. However, the circular groove type may not be effective for high-load applications, as it may not provide enough lubrication in areas of high pressure.

Straight Groove Type:

The straight groove type consists of a series of parallel lines etched into the bearing surface. This pattern is typically used in high-load applications, where the weight of the rotating or sliding part is concentrated in a small area. The straight groove type provides better lubrication to these areas, reducing wear and extending the life of the bearing.

Single Loop Groove Type:

The single loop groove type consists of a single groove that spirals around the bearing surface. This pattern is useful for low-load applications, where lubrication needs to be distributed evenly across the surface of the bearing. However, the single loop groove type may not be suitable for high-load applications, as it may not provide enough lubrication to areas of high pressure.

Double Loop Groove Type:

The double loop groove type is similar to the single loop groove type, but with two grooves that spiral around the bearing surface. This pattern is useful for high-load applications, as it provides better lubrication to areas of high pressure. The double loop groove type is also more effective at preventing the buildup of debris in the bearing surface, which can cause wear and damage over time.

Straight & Circular Groove Type:

The straight and circular groove type is a combination of the straight and circular groove types. This pattern provides both good lubrication distribution and high-load capacity, making it ideal for a wide range of applications. The straight and circular groove type is particularly effective in applications where the load on the bearing changes frequently, as it can adapt to changing conditions.

Figure 8 Groove Type:

The figure 8 groove type consists of two grooves that intersect in a figure 8 pattern. This pattern is useful for applications that require high-load capacity, as it provides better lubrication to areas of high pressure. The figure 8 groove type is also effective at preventing debris buildup in the bearing surface, making it a good choice for applications that are exposed to harsh environments.

Double Figure 8 Groove Type:

The double figure 8 groove type is similar to the figure 8 groove type, but with two intersecting figure 8 patterns. This pattern provides even better lubrication distribution and load capacity, making it ideal for high-load applications. The double figure 8 groove type is also effective at preventing debris buildup, making it suitable for harsh environments.

Choosing the right bronze bearing groove type is crucial for ensuring optimal performance and longevity. Different groove types provide different advantages depending on the specific application, load capacity, and environmental factors. By understanding the advantages and disadvantages of each groove type, designers and engineers can make informed decisions when selecting the best bearing for their application.

A bronze bushing with a self-lubricating spiral groove is a specialized mechanical component that is designed to reduce friction and improve the overall efficiency of an assembly where moving parts are involved. The key elements of this component are explained below:

Bronze Bushing: A bushing, also known as a plain bearing, is a simple type of bearing that is used to reduce friction between two surfaces sliding against each other. In this case, the bushing is made from bronze, which is a metal known for its good strength, conductivity, and corrosion resistance. It’s a popular choice for bushings because of its durability and reliability under different conditions.

Self-Lubricating: Self-lubricating refers to the ability of the bushing to generate its own lubrication over time. This is usually achieved by impregnating the bronze with a lubricant, like oil or graphite, which slowly seeps out during operation, reducing the need for regular manual lubrication. This feature greatly enhances the longevity and maintenance intervals of the machine parts where the bushing is used.

Spiral Groove: A spiral groove is an architectural feature in the bushing designed to guide and distribute the lubricant across the surface. This design helps to optimize the lubrication process by ensuring that every part of the bearing surface is covered. The spiral groove also serves to retain the lubricant for a longer time, thus improving the efficiency of the system.

These bronze bushings with self-lubricating spiral grooves are commonly used in various industrial applications, such as engines, motors, gearboxes, pumps, and heavy machinery, to provide a maintenance-free and efficient solution for reducing friction between moving parts.

The lubricating oil groove inside the brass sleeve is processed as follows.

The pitch should be hung twice the length of the workpiece, the minimum speed, one thread for each positive and negative thread, and the thread joints are fully optimized.

Bronze bush, divided into a variety of, including machine bronze groove, bronze bearings, etc. Oil-lubricated bearings, used in a variety of large, heavy machinery, is an important component of the machinery. Bronze bushings have high hardness, excellent wear resistance, not easy to produce bite phenomenon, have good casting performance and cutting performance, and have good corrosion resistance in the atmosphere and fresh water.

In the sliding bearing open oil hole and oil groove should be noted: oil hole and oil groove can only be opened in the non-load area; axial oil groove can not be opened along the bearing width to prevent end leakage. Sliding bearing (sliding bearing), in the sliding friction under the work of the bearing. Sliding bearing works smoothly, reliably and without noise. Under the condition of liquid lubrication, sliding surface is separated by lubricant without direct contact, but also can greatly reduce friction loss and surface wear, oil film also has a certain vibration absorption capacity. But the starting friction resistance is large. The part of the shaft supported by the bearing is called the journal, and the parts matched with the journal are called the shaft tile. In order to improve the frictional properties of the surface of the shaft tile and cast in its inner surface of the friction reducing material layer called bearing lining. Shaft shingles and bearing lining materials are collectively referred to as sliding bearing materials. Sliding bearing applications are generally in high-speed light load conditions.

Bronze groove bush: Bronze bush (also called bronze bush, bronze bearing, bronze bush) is a very critical part of the machinery and equipment of the bronze parts. His role is to

　　a, reduce the sliding friction of the equipment in operation, reduce power loss.

　　b, greatly increase the service life of wear parts in the operating equipment, reduce repair and maintenance costs, for higher equipment utilization;.

　　c, effective protection of steel parts in contact with it from wear and tear, when the bronze parts wear easy to replace.

　The installation part of the oil groove bronze sleeve is located between the spindle and the support frame of the transmission equipment, the pressure is very high, his material and size requirements are relatively high, especially the clearance between him and the spindle and steel bracket is an important technical difficulty, due to the manufacturing and installation errors, in operation is easy to cause the bronze sleeve crack or even break, spindle wear, cracking and other malignant equipment accidents. So the choice of material and processing size to ensure that the oil groove bronze sleeve is the key to the normal operation of the equipment. The wear frequency of the oil groove bronze sleeve is closely related to the working condition and lubrication and the material of the bronze sleeve.
