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, wear resistance bearing is called self-lubricating bearing. Because self-lubricating bearings are used in parts where lubricants cannot be used or in parts where lubricants are poor and used in stable parts such as boundary lubrication and mixed lubrication, these self-lubricating bearings are also called “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!

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.

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

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 Impregnated Bronze Bushings

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.
