What to Know About Flange Block Bearings

Flange Block Bearings is very important in the construction industry. They make the work of fitting and repairing pipes much easier. The most common type of these is the straight flange, which has a smooth external surface and is often provided with an inner layer of steel to prevent it from rusting. Other types include the tapered flange, which have a tapered, slanted external surface, as well as the perforated flange, which have a shallow channel and two perforations along its external surface. The type of flange that you will need depends largely on the type of construction that you are doing.


The flat flange is made of steel and has a cylindrical inner surface, whereas the tapered flange, like its name suggests, has a slanted external surface. When it has been heated, it becomes harder and can be used in applications that have greater load variation, such as in the case of ship-mounted pipeline. Another type of flange, the perforated flange, has an internal strainer at the edge and is used mainly in the transportation industry. In this case, the cylindrical inner surface of the flange blocks is made of iron and is available in different thicknesses.


All the aforementioned types of flange have the same basic component, which is a strip of metal that is used to form the external face of the flange. Most commonly, the material used is sheet metal or aluminum, although other materials such as steel may also be used. The thickness of the strip is dependent on the application, so thin-wall fabrication is common for pipes and other construction equipment. Some manufacturers offer a wide range of sizes, so even though a certain type of flange may not be available in your area, you can easily have the item custom made to your specifications.


When looking for the right type of flange block bearing, it's important to identify whether the application will require bolts or screws to attach the face of the flange to the shaft, or if it will be fastened with screws only. Bolt type options include captive and self-tightening, and although a captive model requires a special qualified person to install, self-tightening screws are easier to install. Also, the number of nuts to be used to determine the number of bolt holes. For example, a one-bolt flange usually has eight to ten holes.


Other characteristics to look for in a flange block bearing include the manufacturing process used to create the product and material, such as the ratio of steel to aluminum and the material's heat-hardening ability. All of these factors play an important role in the performance and longevity of the bearing product. It is important that a manufacturer takes care to ensure that processes used to make their products are as high-quality as possible. In addition to checking for quality specifications during inspection, it's also crucial to perform quality assurance tests on the bearing product to ensure that the materials were well made and that they meet expected performance levels.


While flange blocks can be a worthwhile investment, purchasing the wrong type could be a costly mistake. A poorly chosen bearing could have limited life spans and/or poor performance. By purchasing the correct type, it's possible to have a product that performs well and lasts for many years. Additionally, by making sure that the installation method and manufacturer are reliable, it's possible to get a cost-effective and reliable flange block bearing.
