Bearings used in machinery that must have a frictionless power transmission need to be carefully selected in order for them to be able to withstand the conditions under which the machinery operates. This is because friction causes wear and tear on bearings over time. When choosing bearings, it is necessary to give careful consideration to a wide range of factors, beginning with the type of load that will be imposed on the bearings while the mechanical operation is being performed and continuing all the way through the required maintenance that must be performed in order to ensure that the bearings will perform as intended. As a supplier of bearings in Singapore, SLS has everything you need to know about choosing the appropriate bearing for the application of your machine, regardless of whether you require a frictionless transmission for HVAC, food processing, or any other critical applications. SLS also has everything you need to know about selecting the appropriate bearing for the application of your machine. When selecting the appropriate bearing, you need to be aware of seven different factors, which are outlined in the following list:
1. The Characteristics of the Loading
There are three distinct kinds of loads that you need to be conscious of before you start looking for a bearing, and they are as follows:
Radial loads are load forces that are perpendicular to the rotating shaft, and this is what gives them their name.
When combined, the load forces can be either radial or axial, or they can be interchangeable between the two. Combined loads can also have load forces that are neither radial nor axial.
It is absolutely necessary that you have an accurate understanding of the type of load because different rolling elements, bearing materials, and raceway rigidities are ideally suited for different kinds of applications. In addition to this, the load's weight is something that needs to be taken into consideration as well. In contrast to thrust bearings, linear bearings are only able to support axial loads, whereas thrust bearings can simultaneously support radial and combined loads. To be more specific, given that tapered roller bearings are able to withstand high radial loads in addition to axial loads, these bearings are suitable for use in a wide variety of applications across a number of different industries. This is because tapered roller bearings are capable of resisting high radial loads as well as axial loads.
2. The Rate at Which the Transmissions Operate
Bearings used in various systems run at varying speeds; therefore, the bearings used in those systems need to be able to withstand not only the varying speeds but also the varying temperatures. The operations cannot be optimized to their full potential until this step is completed. Because even slight misalignments during the installation or maintenance processes can cause vibrations, an increase in temperature, and eventually downtime as the wider components wear out, precision bearings are required when high speeds are present. This is due to the fact that even slight misalignments during the installation or maintenance processes can cause these issues. When it comes to transmission speeds, ball bearings are typically the best option for higher rotational speeds (measured in rotations per minute, or RPM), whereas roller elements are typically the best option for lower transmission speeds. Both of these measures are referred to as revolutions per minute.
3. The Temperatures at Which the Components Are Operating
During the course of the normal operation of the entire piece of machinery and mechanical device, it is possible for temperatures to reach as high as 350 degrees Celsius, which is equivalent to 660 degrees Fahrenheit. Because the material used in bearings can buckle when subjected to heat stress, this is an important consideration to take into account. Additionally, the lubricant can dry out, leading to increased friction in the transmission if it is an oil-based lubricant that is being used. Specialized engineering has been implemented by some manufacturers in the production of their bearings, making them capable of withstanding loads and transmissions at high temperatures. One of these manufacturers is SKF Bearings, and china high quality ball bearing factory is an important source for components at the bearing supplier that you have in Singapore. SKF Bearings is located in Singapore.
4. The Prerequisites for the Lubricant Specifications
In order to keep the power from moving between the different components without any resistance caused by friction, it is necessary for there to be some kind of lubrication present in the rolling element of a bearing. This lubrication must also be present in the cage and the raceway. You ought to be well-versed in each of the three distinct kinds of lubricant that are on the market. Each one calls for a different kind of application and has a different set of requirements for how it should be maintained and the benefits it brings to the machine equipment. In addition, each one also has its own unique set of requirements regarding the benefits it brings to the machine equipment.
Dry lubricant is a type of lubricant that can also be referred to as grease, solid film lubricant, oil lubricant made from petroleum or synthetic oil, and dry film lubricant.
You can gain further insight into the various types of lubrication by reading our other article, which is titled The Importance of Lubrication in Bearings and Other Components. This will allow you to determine which type of lubrication is the most appropriate for the bearings that you have chosen.
5. The Oil That Is Used To Lubricate The Bearings
Bearing sealant, which is also known as retaining compound, is used in order to help reduce the risk of lubricant contamination and excessive evaporation. This is accomplished with the help of the bearing sealant. There are two distinct varieties of cores, the first of which is an encasing that is known as a shield. The second kind of core is an unencased core. The particular encasing in question is a component of the bearing, and its production typically involves the utilization of the same kinds of materials. Nevertheless, these shields can also take the form of a rubber seal if the operation in question does not involve conditions characterized by high load temperatures or speeds. This holds true in circumstances in which neither of these factors are a cause for concern. When the bearing is installed, the inner ring will drag the even bead of a compound down the shaft to fill any imperfections in the assembly. This will ensure that the bearing functions properly. The other kind of retaining compound is one that is put on the shaft of the rotating component. This kind of compound is used to keep things in place.
6. The Program for Preventive Measures
There are three distinct approaches to maintenance, namely preventative, predictive, and reactive maintenance. Utilization of each of these three aspects is necessary to ensure that operations will proceed as planned. On the other hand, you will need to perform additional maintenance on the components of your machine that are located in the areas where specific bearings are installed. For example, bearings that are lubricated with oil-based lubricants require more frequent maintenance than bearings that are lubricated with water-based lubricants. In addition, bearings that are purchased for a lower price may be required to undergo a greater quantity of predictive and preventive maintenance, which will ultimately lead to an increase in price over the course of their lifetime. Purchased bearings from well-known manufacturers such as SKF or INAOn the other hand, bearings purchased from a reputable brand name retailer require significantly less maintenance than generic china high quality ball bearing factory.
On this page, the distinction between predictive maintenance and preventive maintenance is broken down into its component parts and examined in greater detail. Investigating the possible causes behind why preventative maintenance is the most all-encompassing strategy is also something that needs to be done.
7. The Situation in Relation to the Whole World
When selecting the appropriate bearing for your machine application from the inventory that is offered by your bearing supplier, the operating environment should be the very last thing that you give any thought to. It is essential for the transmission module to make use of specific bearing materials, lubricants, and shields in order for it to function properly when subjected to harsh operating conditions. The manufacture of bearings requires seven primary components in order to be completed successfully:
Carbon Steel
Metals that are Ceramic Hybrids Made of Chrome and Steel
a polymer plastic stainless steel that is stainless steel.
