Characteristics Of Self Lubricating Bushes

Lubrication is divided into fluid lubrication, mixed lubrication, boundary lubrication, and solid lubrication.
In the field of solid lubrication, the self-lubricating bushes material itself shows good friction characteristics, due to the self-lubricating function, graphite plugged bronze bushings this special structure improves the life of mechanical equipment, therefore ensuring long-term high performance. self-lubricating bushes are used in parts where lubricants cannot be used or where lubricants are poor and in stable parts such as boundary and mixed lubrication, hence these self-lubricating bearings are also known as “self-lubricating bearings”, “dry bearings”, etc.

Why Use Self-lubricating Bearings?

1. Self-lubricating Bushes Save your cost

There are more costs involved in using lubrication, such as: buying oil, machining oil passages in the shaft or housing, additional seals to retain the lubricant, recycling the machine, etc. In addition, regular maintenance costs are very high, and machine downtime during maintenance can also reduce operating efficiency. Self Lubricating Bushes costs can be cut by reducing the use of lubrication!

2. Lubrication consumes energy and pollutes the environment

In addition, the use of lubrication will greatly reduce the energy efficiency of the contact between the oil seal and the shaft, resulting in increased energy consumption. Moreover, it will also bring a very high risk of environmental pollution. Now that the environmental protection regulations are becoming more and more strict, these pollutions may make the machine unable to pass the license of the government or various regulations, resulting in an unusable situation!

Select Your Self Lubricating Plain Bushes Material

Bronze Bush – Plain: A plain bronze bush is a cylindrical bearing made from bronze material that is used to reduce friction between two moving parts or surfaces. The plain design refers to the absence of any grooves, flanges, or integrated lubrication features. These bushes are known for their durability, wear resistance, and ability to withstand corrosive environments, making them suitable for a wide range of applications in various industries.

  • Bearing Bronze Alloys: Bearing Bronze Alloys are for general utility bearings and bushings and are highly resistant to impact, wear, and corrosion. Alloys include C93200, C93600, and C93700.
  • Aluminum Bronzes: Most valued for their higher strength and corrosion resistance as compared to other bronze alloys. Alloys in this family include C95400, C95900, C63000, C63020 C95510,C95500, and C61400.
  • Manganese Bronze Bushing: It can operate under very high loads and speeds. Besides excellent mechanical qualities, these alloys have good corrosion resistance. Alloys include C67300, C86300, C86400, and C86500.

Types Of Self-Lubricating Bushes

Self-lubricating bushes are available in various types, each with its unique properties and characteristics.

  • Metal-polymer composite bushes: These bushes consist of a metal backing with a porous bronze sinter layer, impregnated with a solid lubricant.

  • Bimetal bushes: These bushes consist of a steel backing with a bronze sinter layer, impregnated with a solid lubricant.

  • Casting bronze bushing & Graphite bronze bushing
  • Wrapped bronze bearings: Their running surface is provided with diamond-shaped lubrication pockets or a hole pattern.

The Advantages of Self-Lubricating Bushes over Traditional Bushes

Self-lubricating PTFE Composite Bearing: This type of bearing is designed with a composite material that incorporates polytetrafluoroethylene (PTFE) fibers, providing self-lubricating properties. The PTFE fibers help to reduce friction and wear between moving parts, eliminating the need for additional lubrication. These bearings are known for their low friction coefficient, high wear resistance, and excellent performance under various loads and speeds. They are suitable for a wide range of applications in various industries, including automotive, aerospace, and industrial machinery.

Self-lubricating bushes offer several advantages over traditional bushes, including:

  • Self-lubricating bushes require less maintenance as they are designed to continuously lubricate themselves during operation. This means less downtime and cost savings.

  • The self-lubricating properties of these bushes also mean they last longer than traditional ones.

  • oilless bushes can help improve equipment performance by reducing friction and wear. This can result in smoother operation, less noise, and less vibration.

  • Better Load Capacity than traditional bushings and Environmentally Friendly

Self Lubricating Graphite Plugged Bronze Bushing

Beautifully crafted leather products.

Plug Graphite Bushings – This product is a cast bronze bushing that has been milled and plugged with graphite plugs. The graphite acts as the lubricator. These are used in applications where the properties of the oil-impregnated bushing would not suffice. Examples of these are high-temperature applications or applications with a heavy load-bearing requirement.

Sintered Oil Impregnated Bearings

Sintered Oil Impregnated Bearings

Oil Impregnated Bearings are made of porous bronze or iron and are usually filled with oil. During operations, the lubricant which is already impregnated in the bearing material is released through pores from the sliding layer of the bearing thereby lubricating the contact surfaces. The lubricant is dispersed quite uniformly over the contact layer providing low friction between the moving surfaces.

When the motion stops, the micro-porous material acts as a sponge to reabsorb the oil, preventing excessive build-up of the lubricant on the shaft and eliminating any messy dripping that comes with manual oil applications.

A specially coated surface is added at the top of the sliding layer to provide low friction at the start-up of the operations to allow time for the impregnated lubricant to reach the bearing surface.

Graphite Plugged Bronze Bushing

Graphite Plugged Bronze Bushings are a common Self-Lubrication bearing suitable for high load, low-velocity applications. Lubricant, normally in the form of Graphite or PTFE, is embedded into Bronze Plain bearings as polka-dots covering the surface of the bearing in a systematic pattern. As the bearings slide the solid graphite or PTFE lubricant is deposited on the bronze surface of the bearing creating a lubricant film.

Graphite has some unique properties that make it an excellent lubricant. Chemically, it is one of three common allotropic forms of carbon, with amorphous carbon and diamond being the other two. In contrast to diamond, which has a very dense and strong crystal structure, graphite has a two-dimensional crystal structure, strong in two dimensions but weak in the third. Its atoms are arranged in parallel sheets that are easily sheared off, giving graphite it’s characteristic slippery feeling. It also has a near-zero coefficient of thermal expansion. This enables it to be an excellent solid lubricant option, especially in high-temperature conditions.
