~ How the right bearings can lead to performance for cars ~

A car has about 30,000 components, from basic body structures to individual bolts and screws. Each part has an integral role in keeping the car running and this also applies to the bearings. A vehicle with a conventional engine will have an average of about 100 to 150 bearings, many of which are key to reducing friction and energy consumption and ensuring safe operation. In this article, Chris Johnson, Managing Director of specialized bearing supplier SMB Bearings explains the importance of automotive bearings.

When looking at important parts of the car, bearings are often overlooked, but incorrect or defective bearings can cause noise and friction and even increase emissions and affect the customer experience. Bearings are present in many components of the vehicle, and the type and size will depend on the requirement. Automotive parts and their functions are so diverse that the requirements for their bearings also vary considerably. Several types of bearings are used depending on many factors, such as radial load, axial load and operating condition.

Bearings are found in all types of vehicles. From air conditioning and water pumps to seat and mirror adjustment mechanisms, many of the car’s important functions would be far less efficient or even impossible without the use of bearings. Vehicles powered by internal combustion engines have a significant amount of moving parts, which makes the bearings an integral part of the trouble-free operation of components such as alternators, power steering and gearboxes. Demand for electric motor bearings is also growing as electric vehicles (EVs) become more popular, with lighter, smaller bearings important for improving the efficiency of EV propulsion.

Choosing the right bearing for automotive applications is important to optimize vehicle performance, ensure safety and reduce emissions. Above all, buyers must consider quality and reliability. Choosing the right bearing size and material can do all the different for the driver experience, ensuring fluid movement and reducing noise.

The bearings used in automotive applications must withstand harsh conditions and long periods of stress under heavy loads, so the choice of material is paramount. Throttle bearings, for example, are key to regulating airflow and are exposed to high levels of vibration and extreme temperatures. Ball and plain bearings are traditionally used for these applications, but sealed needle roller bearings are becoming increasingly popular due to their greater vibration tolerance.

Longevity is also a consideration – bearings are often installed for the life of the component, but defective or worn bearings can produce noise or reduce efficiency and may need to be replaced at fixed intervals. Maintenance can be minimized by selecting a bearing that is guaranteed to extend the recommended service life. Buyers can look for ISO / TS16949 compliant bearings to ensure that the products meet the internationally recognized quality management standard for the automotive industry.

The efficient operation of the bearing does not stop only at the bearing itself – the choice of lubricant is also a factor and can change the efficiency. Wide temperature greases are suitable for general automotive use due to the range of temperatures to which automotive bearings are exposed. Shock absorbers reduce noise and vibration in slow-moving steering column bearings, although they are widely used in other applications to minimize rattling and squeaking or to give a sense of quality. This type of grease can be found in seat guides, sunroofs, center consoles, dials, sliders, switches, cup holders, electric mirrors and locking systems.

Each of the thousands of car parts is essential for performance and bearings should not be overlooked. Car bearings are an integral part of the safe and reliable operation of the vehicle and of improving the efficiency of both conventional and electric motors. When choosing bearings, buyers should make the choice of bearings in terms of quality to ensure optimal performance.
