What To Look For With Flanged Bearings
Flanged bearings are essential in operating a wide range of machinery and equipment, including motors, pumps, fans, conveyors, and more. They are designed to withstand axial and radial loads, which is beneficial for applications where the shaft axis is perpendicular to the mounting surface. Moreover, they contribute to equipment’s longevity and smooth functioning as they can support heavy loads.
When selecting flanged bearings, it is vital to consider key elements to ensure that you have the appropriate component for your needs. The following factors should be taken into consideration when making your decision:
It is critical to select bearings made of materials compatible with your application because they can affect overall performance and durability. Several factors — operating temperature, exposure to corrosive substances, load requirements, and more — play a role in determining the best material for a specific purpose.
For example, stainless steel is the best metal for corrosive environments. Meanwhile, cast iron is an excellent choice for high-load applications, as it is extremely strong and durable. It is also important to note that most components are not made from a single material. Therefore, you must determine which combination works best for you.
2. Load Capacity
Load capacity refers to the maximum load a bearing can withstand without failing. It is typically determined by various attributes, such as the size, material, and design of the bearing. Before selecting a flanged bearing, you must identify your application’s anticipated radial and axial loads. This information can be obtained from the manufacturer or by using engineering calculations.
The size of the flanged bearing determines the load capacity and the shaft size it can support. Therefore, check whether or not the bearing size matches the shaft and mounting dimensions. It is also recommended to consider the clearances between all parts and components to ensure that everything operates smoothly without excessive wear.
Flanged bearings are available in two main types: open and sealed. Every kind of sealing offers distinct advantages and disadvantages, making it important to choose the right type for your application.
Open bearings are the most economical option and do not have seals or covers to protect against contamination. However, they do require regular lubrication to keep them functioning properly. They are also susceptible to contamination from dirt, dust, and other particles that can reduce their lifespan.
Sealed bearings have seals or covers that protect against contamination and require less maintenance. They are more expensive than open bearings but provide better protection against contamination and typically have a longer lifespan. There are various types of sealed bearings, including contact seals, non-contact seals, and labyrinth seals.
Proper lubrication is crucial for the performance and longevity of flanged bearings, as it helps to reduce friction, minimize heat generation, and prevent contamination. They can be lubricated in various ways, including grease, oil, and a combination of the two.
Grease lubrication is a convenient and economical option, providing a long-lasting lubricating film that reduces the need for frequent re-lubrication. On the other hand, oil lubrication offers better cooling and is recommended for high-speed applications.
Flanged bearings operate at specific speeds, making it critical to select the appropriate speed rating for your application. When a bearing operates at speeds faster than its rated velocity, it generates excessive heat, shortening its lifespan and potentially leading to failure. Meanwhile, if it runs at bandwidths lower than its rated speed, it may not provide the required performance.
