Improving Performance With Metallic Self-lubricating Bearings
In the past hours were spent making sure that machinery components were well oiled, greased and lubricated to improve the life span of equipment. As with everything in the modern day and age this process has been all but negated in some applications with the use of metallic self-lubricating bearings saving time and money in a variety of industries.
These types of self lubricating bearings use a primer that is integrated into the design of the component. Through use, polymers are released that fulfil the requirements for lubrication. There are many reasons why lubrication is necessary in metallic self-lubricating bearings as well as other components that are involved in different types of machinery and equipment.
The main reason is to eliminate wear and tear. All moving parts in various types of machinery cause friction to varying degrees. This friction wears away at the surface of metallic self-lubricating bearings. The lubrication forms a layer between different working parts in the machinery to minimise the friction that takes place as part of the operating process.
Friction in turn causes heat which is also not ideal in most types of machinery. Heat is also not ideal in most types of manufacturing and production processes. In minimising the amount of friction, less heat is created in the operation process of different types of machinery making them better suited to specific industrial applications.
Dust and dirt is also problematic where machinery is involved. Any type of debris that can get caught in any mechanisms will increase the wear and tear, friction and therefore heat producing properties of machinery and equipment with working parts. Metallic self-lubricating bearings assist in minimising the dust and debris that can be attracted by other forms of lubricants such as oils and grease. The end result of these types of bearings is increased performance which in turn has a great effect on productivity.

How Dry Bearings Minimise Friction, Heat And Wear And Tear
While most people believe that dry bearings don’t require or provide any type of lubrication this is not actually the case. Dry bearings in fact produce lubrication in a different way to traditional lubricants like oil and grease. This dry lubrication system consists of a layer that minimises friction and the resultant heat production that is created within the moving parts of machinery.
The dry lubrication layer on these types of bearings consists of different types of materials depending on the application that the bearing is to be used for. The layer or coating needs to take into account the following factors in the choice of suitable material:
- How abrasive the condition of the bearing will be within an application.
- The roughness or smoothness of the surface upon which the bearing will be applied.
- The necessary load carrying capacity of the dry bearing which includes the pressure and the load requirements.
- The speed of the two surfaces relative to each other.
The addition of the layer or coating to a dry bearing is not complicated especially when taken in relation to the reliability and quality that is provided by the bearings. However, different techniques are used in the application of the layer depending on the type of material the bearing is made of and the material that the layer is created from.
It is of utmost importance that the layer or coating is bonded correctly and firmly to the dry bearing. This can mean the difference between the production of a success of a bearing in minimising friction, heat and wear and tear. These dry bearings not only minimise the three factors involved in moving parts in machinery but make the bearings almost indestructible while exceeding the lubrication properties of traditional lubricants such as different types of oils and grease.

Propulsion Systems – How They Work
Propulsion systems refer to the method used to make certain vehicles mobile using a propeller or other means to cause a change of velocity in a specific direction. Propulsion is mainly used in flight and water faring vessels and there are very few land bearing applications. While there are many different types of propulsion, the one that people are the most familiar with are propellers.
The principle behind propulsion systems is to create a thrust that pushes an object forward. In the example of a propeller, thrust is created by using air or water as an element to create the necessary thrust. Air is less dense than water meaning that the propeller can turn faster for the movement of vehicles that travel by air than by water. Air is also the medium used to create propulsion in land going vehicles however there is substantially more drag in land vessels making this less than ideal.
There is a complicated calculation that is used in the design and creation of propulsion systems to meet the requirements of specific applications and vessels. The mass flow of the water or gas through an engine in relation to the exit velocity of the medium will determine the power of the propulsion. The specifications of the vessel then need to be taken into account.
How heavy is the vessel and how much drag will be created in creating forward thrust needs to be calculated to determine how much propulsion will be necessary. The balance and stability of the vehicle will determine the placement and directionality of the force from the propulsion systems. The necessary velocity of the vehicle will also affect the calculation of the force that will need to be produced. Specific calculators and simulation models are used to simplify the technical aspects of designing and producing effective propulsion for specific applications.

Orkot Marine Bearings – TLMM and TXMM Grades
Orkot marine bearings have two different grades for manufacturing products for use in either conventional sea and other water faring vessels or speciality vessels such as naval vessels. The TLMM grade is used for conventional vessels and the TXMM grade for naval and other speciality vessels.
Orkot TLM marine incorporates solid lubricants in conjunction with reinforced polymers for greater durability and wear resistance. In addition, these Orkot marine beatings create less swell in water applications meaning that more stability is created for the vessel. The bearings are advanced and use different types of installation processes in propulsion to meet the requirements of a number of different types of vessels.
Orkot TXM marine in comparison uses a thick PTFE layer instead of solid lubricants to provide an even greater deterrent to wear and tear. The PTFE layer also lowers the amount of friction that is created in the sliding and working parts of the propulsion systems in water going vessels. This minimising of friction makes these types of Orkot marine bearings suitable for use in some dry applications where sticking and slipping often causes problems.
There are a number of different types of both the TXMM and TLMM marine bearings from Orkot to meet the specific requirements in wet and dry applications. These requirements refer to the necessary load carrying capacity of the bearing, chemical and abrasive resistance, type of suitable lubrication for the bearings, minimising the effects of mechanical vibrations etc.
One of the greatest benefits of using all types of Orkot marine bearings is that the products are manufactured to be more environmentally friendly than their counterparts. The bearings are asbestos free and use not materials or substances that can be considered hazardous to the environment and to people alike while in operation for their specified applications or purposes.

Bronze Bearings – Self-lubricating, Oil-less And Plain
One of the most innovative products to hit the bearing manufacturing industry is sintered bronze bearings. Sintered bronze bearings are impregnated with oil that is released while the bearing is in operation. This oil is released through the friction that is created between two moving parts.
The oil from the sintered bronze bearings then forms a thin layer between the working parts of machinery or equipment. This layer of oil provides protection from wear and tear ensuring that the bearing as well as the mechanical working point last longer. The oil layer also minimises friction which creates heat which is not ideal for most manufacturing or industrial processes.
While other types of bearings use the same technique of applying oil or grease to minimise friction and wear and tear, these lubricants need to be applied manually. This means that you run the risk of not applying enough lubrication or that the lubrication can be disappear during the operation of the equipment leading to breakdown. This is why sintered bronze bearings are also often referred to as self-lubricating bearings.
In other processes where it is necessary to create an environment where no contaminants are present, oil-less bearings are better suited to the task at hand. Oil-less bearings are often also referred to as self-lubricating bearings but this is in fact a misnomer as no lubricant is present in the operation of an oil-less bearing. Oil-less bearings are also manufactured in bronze.
Bronze is the ideal metal to use in the production of all types of bearings as the metal is both malleable making it easier to deal with as well as durable. There are many other properties of bronze that make them great for the manufacture of bearings.
