Plain Bearing SELF Lubrication

types of plain bearing

Plain Bearings (Sliding Friction Bearings): Plain bearings operate on the principle of sliding friction and do not use rolling elements; because there are no moving parts, they are usually quieter than anti-friction bearings. Sliding bearings can be used in rotary or linear applications. For example, a shaft that rotates in a bore represents a sliding bearing being used to limit rotational motion; a sliding drawer represents a linear application. Sliding bearings are often selected for high load, low speed applications.

  • There are two main categories of bearings, plain bearings and anti-friction (rolling) bearings. Plain bearings operate on the principle of sliding motion, while rolling bearings operate on the principle of rolling motion.

  • Sliding bearings are also referred to as plain bearings, sleeve bearings, bushing bearings, slide bearings, bimetal bearings, dry bearings. Unfortunately, the application of these terms is not always correct, which leads to confusion. For example, bimetal bearings are bearings made from steel and bronze, a soft metal alloy, but people often refer to all sliding bearings as “Babbitt bearings,” which is incorrect.

  • Sliding plain bearings are used in many large machinery items, including steam turbines and large marine two-stroke vessels, but they are also used in almost all internal combustion engines because they allow the bearings to be mounted in two or more separate components.

Self-lubricating PLAIN Bearing Solution

What is a journal bearing?

The area on the shaft where the bearing fits is called the journal. A journal bearing is a bearing that is mounted on a journal, but it can also be called a plain bearing, or a bimetallic bearing, etc. This is also true. Confusion often arises about the naming of plain bearings because many of the names are correct, but sometimes applied incorrectly. Journal bearings can be manufactured from a single piece (solid) or multiple pieces (split or multi-piece), and they can be lubricated or non-lubricated.

Sacrificial plain bearing material: The material of the plain bearing is selected as the sacrificial material compared to the journal on which it is mounted (the area on the shaft where the bearing is located). If the two materials rub together, the sacrificial material is the first to start wearing. Plain bearings are sacrificial because otherwise the journals would wear more than the bearings. This is undesirable because the journal (part of the shaft) is usually more expensive and more difficult to replace than the bearing.

  • Application for plain bearings: Excavators with plain bearings

    Agricultural machinery and construction equipment often have very tough jobs. The moving parts of excavators, dump trucks, tractors and various tillage and planting machines in the field are subjected to very heavy loads. Dirt, dust, rain and snow are especially tough on materials that are not resistant to corrosion.

Plain Bearing Solid, Split or Multi-Part, Tribological Components

  • Types of bearings: one part or several? Plain bearings can be solid, split or multi-part. A solid plain bearing is the simplest form of bearing and consists of a cylinder with a hole drilled in the central shaft. A split bearing is similar to a solid bearing, but the bearing consists of two pieces. A multi-piece bearing consists of more than two pieces. Examples of solid plain bearings include bushings and sleeves.

  • There are several reasons for the use of split plain bearings:

    1. Split plain bearings can be mounted on shafts that are not continuously straight.
    2. Split plain bearings can be mounted without removing the shaft.
  • Plain bearings are sliding cylindrical bearings made of two different materials. This type of bearing has a thin lining on the bearing surface that mates with the journal. The bearing surface facing the journal is usually coated with a sacrificial material, such as a metallic sliding layer, while the main bearing body (which does not come into contact with the journal) is made of a different material, such as steel, or then copper.

  • Bushing bearings are plain cylindrical bearings manufactured from a single material. There is only one difference between a sleeve bearing and a bushing bearing; a sleeve bearing uses a thin bearing material to mate with the shaft, while a bushing bearing is manufactured entirely from a single material. Bushings are usually thinner and structurally weaker than sleeves.

Tribological Components

Types of Sliding Bearings … Sliding bearings, also known as bushings, sleeves or sleeve bearings, are usually cylindrical in shape and contain no moving parts.

low friction bearing

There are significant benefits to using self-lubricating mold components, but the premise is that the mold maker really understands what these components are: essentially a traditional component with added lubricant, in the form of a graphite plug. Graphite is a solid lubricant, so for those who are accustomed to using liquid lubricants such as grease or oil, solid lubricants may seem a bit strange, and the same is true for graphite itself.

What looks like a solid graphite block is actually a pile of very thin (single-atom thick) crystal sheets. These sheets tend to slide on each other and fall off easily, which is a very useful feature in mold manufacturing.

The main function of the self-lubricating part of the mold is to guide and control the movement. This mold is usually made of aluminum bronze, which is an excellent bearing material with embedded graphite plugs. The mating part (the guided part) of the mold is usually made of hardened steel. When the two parts move relative to each other, the very smooth single-atom thick graphite flakes fall off and are distributed on the wear surface. In each cycle, more graphite will be distributed, so this process will continue to be replenished. Graphite does not evaporate and is relatively inert, so the lubrication it provides is basically permanent.

The coefficient of thermal expansion of graphite is close to zero, which means that it will not expand and contract with temperature changes like ordinary substances. It is not metal, but it can conduct electricity like metal. It will not melt either. Instead, it remains solid within the temperature range of 10,000 degrees Fahrenheit, and then becomes a gas. It is not very strong, but it can form composite materials with amazing strength.

Business Impact Through Experience

However, the strangest thing about graphite is its molecular structure. This is a two-dimensional crystal, because we live in a three-dimensional world, a two-dimensional object seems to violate all logic. Graphite is one of the two crystalline forms of ordinary carbon. The other is diamond, which is a traditional three-dimensional crystal, which means it is strong in all three-dimensional spaces. Because graphite is a two-dimensional crystal, it is strong in two dimensions.

We all know that graphite is a good writing tool. The word “graphite” comes from the Greek word grapho, which means “write”. However, its “slip” characteristics are evident in the writing, which makes graphite also very useful as a lubricant. When you rub the pencil lead, it feels oily, even though it is not actually oily. It is completely dry. What you feel is that its single-atom-thick crystals are constantly sliding. It is this effect that makes graphite such an excellent solid lubricant.

Although self-lubrication will increase the cost of conventional components (components that must be regularly oiled) by about 20%, this additional cost has several benefits:

Maintainability. There is no need for regular lubrication, which means that during the life of the tool, the cost savings of preventive maintenance (PM) may be several times the upfront cost of self-lubrication.

reliability. Lubrication is always present, eliminating the risk of failure or shortened life due to skipping PM. In addition, the absence of liquid lubricant means that nothing attracts grit and other contaminants to wear the surface.

Simple design. The use of self-lubricating components eliminates the need for regular lubrication, eliminating design constraints, potentially reducing costs and/or improving functionality.

Cleaning operation. No liquid lubricant drips or splashes onto the parts, which means very clean operations, less waste and rework.

Maintenance Free Bearings Parts, We are experts in solving problems.

Self-lubricating plain bearings are classified as “low maintenance” or “maintenance-free”.

Self-lubricating plain maintenance-free bearings use PTFE material to separate the inner and outer rings; this type of bearing is sometimes referred to as a “PTFE on metal” bearing, plugged graphite. PTFE or graphite is self-lubricating and the bearings do not require maintenance (no added lubricant).

Low-maintenance plain bearings require periodic lubrication; this type of bearing is sometimes referred to as a “metal on metal” bearing.

I know it sounds like we’re bragging, but our skilled team is here to solve your self-lubricating bearing problems, and we offer bearing sizing and material selection to help you design your bushings as quickly as possible. We are committed to minimizing downtime, and we offer quotes and customization services for every bearing size or type, so why not experience the difference?
