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.

A Leap forward in Environmental Sustainability

Environmental Sustainability

Environmental Sustainability Above and Beyond

The environmental agenda, one of the major pillars of sustainable development, often intersects with multilateral trade obligations. Amidst the echoes of environment, climate change, and sustainable development worldwide, NEI has gone above and beyond boundaries to implement sustainability measures with a view to reducing carbon footprint.

Recently having obtained the Green Factory Building Platinum Certification by the Indian Green Building Council (IGBC) for having maintained efficiency of energy consumption and water usage that has been effective in sustaining a village of 300 houses for two consecutive months, plus the ISO 50001 approval for our Jaipur plant as a global recognition for our Energy Management System, we are gearing towards reaching out to more global customers who are looking to partner with an energy-efficient and sustainable enterprise. Our plant in Savli, Vadodara is also IGBC platinum-certified, adopting all green manufacturing practices right from the start.

Environmental Sustainability – Larger Perspective in Practice

Our larger objective lies in reducing energy consumption and improving energy efficiency to support our overarching goal of lowering GHG emissions and Carbon Footprint. In other words, leveraging opportunities to spur the transfer and dissemination of environment-friendly and clean-energy technology as a leading exporter and manufacturer of bearings is what we constantly aim for.

We have been undeterred in extending our endeavor further in our sustainability mission—ranging from implementing all best-in-class practices with supreme standards of water and energy conservation, waste management, and reduction in CO2 emission, to maintaining environmental quality.

NEI’s rainwater harvesting exercise has ensured saving more than 6 million liters of water annually. In addition, wastewater released from the factory is treated on-site in the Effluent Treatment Plant (ETP) and Sewage Treatment Plant (STP). This is in turn used for landscaping the campus areas, consequently resulting in zero discharge outside of the plant. We have reduced water consumption in our Jaipur Plant by 40% in the last five years. In fact, we have a six-sigma project running currently for the reduction of water consumption at the factory site.

The facility in Rajasthan, with its sustainable green building design, also optimizes natural daylight and uses effective lighting and air-conditioning systems to reduce its energy consumption by 39 percent. With its 1500 KW rooftop solar and 100 percent LED lighting, the facility contributes by further decreasing its carbon footprint to 38 percent.

In addition, we have also partnered with our customers for participation in their Carbon disclosure project (CDP), as they strive toward bringing about environmental improvements in their supply chains. However, it doesn’t end there. To maintain environmental quality further, we have also begun to use returnable packaging solutions that help in the reduction of packaging waste.

Our GHG Emission Metrics

To calculate the Green House Gas emissions inventory, we collected activity data from the various locations we identified as sources of GHG emissions. We then applied the emission factors and subsequently derived data on emissions from each source.

We further aggregated this to the corporate level for calculating NEI’s total Carbon footprint. As per the data analyzed for immediate bearing manufacturing competitors for Carbon emission from all 94 manufacturing units around the globe, the emission is around 1.225 M tonnes of the net equivalent. On the contrary, NEI has around 0.105 M tonnes of net equivalent Carbon emission from its 5 manufacturing units.

Towards a Greener Future

While we discuss aspects of environmental sustainability, we cannot play on the back foot when it comes to acknowledging aspects of economic and social sustainability. Sustainable development from a holistic point of view would be achieved only when there is either a balance or a trade-off between these three aspects. NEI takes pride in being part of this mission and will continue playing its part to its maximum potential.
