The Crucial Role of Bearings in Evolving Automotive Technology.
Since the inception of mass-market cars, bearings have played a crucial role in internal combustion engines (ICEs), transmissions, wheels, steering systems, pumps, and more. As automotive technology advances, bearings have kept pace, becoming more sophisticated than ever before. With the rise of hybrid and electric powertrains, bearings have undergone significant transformations.
Hybrid electric vehicles (HEVs) and electric vehicles (EVs) have gained considerable traction in recent decades, emerging as strong alternatives for urban mobility. These vehicles operate with little to no emissions, setting them apart from traditional ICE-powered cars. Unlike their ICE counterparts, EV power trains require fewer bearings due to their simplified design with fewer moving components. Moreover, the bearings used in these new-generation vehicles are far more advanced in terms of design and performance compared to those used in conventional power trains.
The Demanding Power trains of the Future The power trains in next-generation automotive vehicles, such as EVs, pre s ent more cha l l enging conditions for bearings compared to traditional vehicles. EV power trains operate at higher speeds and temperatures, necessitating bearings that can withstand these extreme environments. Unlike ICE vehicles, lubricating EV power trains is not possible. Furthermore, the service intervals for these power trains are typically longer, and in some cases, the mechanical components may require no servicing throughout their lifespan.
At NBC, we are at the forefront of designing, developing, and testing bearings for EVs, incorporating sensorintegrated bearings (SIB) that are uniquely designed and validated. These specialized bearings offer higher rpm capability, reduced noise and friction, increased power density, and extended lifespan. We have already begun supplying them to EV original equipment manufacturers (OEMs) in the two-wheeler, three-wheeler, and passenger car segments, while also collaborating with major OEMs in the commercial vehicle segment. Additionally, we are conducting research on bearings for new fuel vehicles, working closely with OEMs to meet their specific requirements. Our dedication to providing optimized bearing solutions to domestic and international OEMs ensures their readiness for future vehicles.
Challenges in the Bearings Sector while the bearings sector presents promising opportunities, it also faces notable challenges that necessitate attention.
Cost Pressures:
The industry’s competitiveness emphasizes cost-efficiency. Bearing manufacturers must strike a balance between performance, quality, and cost-effectiveness to maintain a strong market position.
Extreme Operating Conditions:
Industrial equipment subject bearings to demanding conditions, including heavy loads, high temperatures, dust, and moisture. Continual innovation and advanced engineering are essential to develop bearings that consistently perform well under such challenging circumstances.
Sustainability and Environment Impact:
With the industry’s increasing focus on sustainability, bearing manufacturers must prioritize environmentally friendly products that comply with evolving regulations related to material usage, waste management, and energy efficiency.
Supply Chain Management:
Efficient supply chain management is crucial for timely meeting industry demands. Any delays or disruptions in the supply chain can have a significant impact on project timelines and customer satisfaction.In conclusion, as automotive technology evolves, bearings play a vital role in next-generation vehicles with hybrid and electric power trains. These advanced bearings must meet the demanding conditions of the power trains while offering enhanced performance and longevity. Bearing manufacturers must navigate cost pressures, extreme operating conditions , sus tainabi l ity concerns , and efficient supply chain management to thrive in the industry’s ever-changing landscape.
