All You Need To Know About Needle Roller Bearings

Needle Roller Bearing

There are different types of bearings available in the market depending on the usage of the product. Needle roller bearing is widely used in many industries such as mining, automobiles, railways, aerospace and many others. This blog will provide all the information about these bearings and will help you to choose the right one for your requirement.

Needle Roller Bearing is one of the economical bearings offering high load capacity due to their special design featuring rolling cylinders with small diameters held between a single race and shaft of a bearing. It also reduces the friction of rotating surfaces making it highly durable. In terms of design, these types of bearings are quite light and small making them fit in those applications which require lesser space. This is a popular type of cost-effective and efficient bearing used by design engineers due to the various technical benefits offered by it.

A needle roller bearing has a diameter to length ratio of between 0.1 and 0.4, measured on the outside of the rollers.

Structure of Needle Bearing - Types of Needle Roller Bearing

There are 4 main types of needle roller bearings, including caged wheel, drawn cup, precision race wheel and thrust wheel. Their typical structure includes an inner wheel or just a shaft to anchor the part, a cage to hold all of the rolling elements within their various compartments and an outer ring. Selecting the right type of needle roller bearing for your specific application depends on a variety of factors such as the necessary load capacity, load type (roller angle), and speed (rpm), as well as the expected temperature limits (typically higher than normal rolling element bearings like ball or sleeve).

Features of Needle Roller Bearing

The Needle Roller Bearings have varied advantages over other types of bearings which are quite larger in size and may not offer the benefits as needle roller bearings offer. The first benefit is that it has a higher load capacity than other bearings. Another advantage it offers is that it delivers the durability to handle the high rigidity of the shaft based on varied types of applications.

Applications Of Needle Roller Bearings

  • Needle roller bearings can be used in various types of machinery such as automotive power transmission systems, two and four-stroke engines, planetary gear sets, and air compressors.
  • Needle roller bearings are especially useful in machinery that requires high temperature, large load, durability, and quiet operation. As the name implies, the rollers are needle-shaped with a wide diameter at one end and a narrow diameter at the other.
  • Needle roller bearings are made of high strength steel with rows of rollers all sharing the same axis. The rollers are supported by the shafts to prevent them from moving in all directions except through the shafts’ axis. The rollers are attached to the shafts by means of cage assemblies.

Common Causes of Bearing Failure and How to Avoid Them

Bearing Failure

Bearings are a crucial part of machinery and failure can cause a significant impact on the overall functioning of machinery. In order to help you ensure the proper functioning of bearing, this blog discusses various aspects of common causes of bearing failure and ways to avoid them.

The bearings offer a lifeline to various equipment and machinery across a wide range of industrial sectors. From a two-wheeler to an aero plane, bearings are used everywhere to support machinery and its operations. They are the small pieces of big machinery that handles load and weight while powering mechanical systems to ensure smooth operations. While every piece of equipment comes with the specified life, this same applies to bearings as well. It depends on multiple conditions on how a bearing fails as it may not be just limited to usual conditions like- wear and tear or corrosion. This blog discusses various causes of bearing failure and tips on how you can avoid it.

Bearing Failure Can Cause Machinery to Break Down

The lack of maintenance of the bearing can result in machinery breakdown which can further impact the functioning of the overall system. This doesn’t only cause an effect on bearing but can also damage machinery in varied ways.

Common Causes Of Bearing Failure & Solutions

The Bearings also do come with service life and there are varied reasons why a bearing can fail.

Here are the different causes of bearing failure and its solutions:

  • Lubrication: The lubrication needs to be applied in a balanced way. If machinery or bearings have been applied with improper lubrication such that- over greasing, under greasing, etc. It may cause various problems and break down the bearing. The only solution to tackle this is to use lubrication in moderation and also ensure the type of grease quality used in it.
  • Working Conditions of Bearings: It is also taken into consideration which environment the bearing is exposed to. If it is exposed to water, dust, sand, etc. it can lead to corrosion or erosion of the bearing surface leading to premature failure. In order to protect bearings from such conditions, it is always recommended to check the usage conditions and suitable conditions where bearings can work efficiently.
  • Bearing Fatigue: The overhauling of the bearing can lead to its failure which can happen due to over-utilization. In such conditions, it fractures the surface of bearings and results in breakdown. The solution to ensure bearing fatigue is to perform scheduled maintenance on a regular basis so as to check for the scope of replacement.
  • Misalignment and Shifting of Bearings: The bearings are very small pieces that are attached to machinery or equipment to make them work. There are possibilities that due to overuse or various other conditions, the bearing can get misaligned from its ideal position making it break down.
  • Installation Errors: Installation errors are quite common as they may lead the bearing to get damaged before its service life. It is always important to ensure and verify that the right kinds of tools are used to install the bearings.

Avoiding Bearing Failures

Bearing Failures can incur costs in varied ways as they can also affect the operational efficiency of machinery and equipment. The best way to avoid bearing failures is to perform regular maintenance, do regular greasing or lubrication based on bearing manufacturer guidelines, and check for any faults or misbehavior. Another aspect to ensure bearing failure doesn’t happen is to install bearings properly with the right kind of tools while taking care of proper fixation and alignment. The bearing maintenance should be a primitive part of the process which helps you save the cost of repairing or replacing the bearing by performing preventive maintenance.

Running Diagnostic Tests to Ensure Smooth Operations

There are various ways through which you can perform predictive checks to ensure that bearings are working as per their defined efficiency. Diagnostic Tests like Root Cause Failure analysis can track any potential failures or wear/tear conditions to ensure that the bearings are in proper shape. Apart from it, IR-based thermography can also be run to conclude temperature-related conditions. These tests are crucial to ensure that the bearings don’t run out before the time.
