Did you know that the main cause of bearing failure is linked to poor lubrication? Often seen as a simple routine task, lubrication is in fact a key factor in equipment performance and reliability. In the field, we have observed that one in two bearing failures is linked to inadequate lubrication, whether due to the wrong choice of product, insufficient or excessive quantities, or poorly managed lubrication intervals. Greases are used in many industrial sectors such as food processing, steelmaking, quarrying, energy and automotive maintenance. What is bearing lubrication? Our expert: Lubrication involves applying grease or an oil film between two moving surfaces to limit friction, reduce wear and protect mechanical components. Given these challenges, several questions arise regarding the choice of the right grease, the quantity to apply, the frequency of lubrication, and so on. To help you understand this better, our expert, Olivier Hautreux, shares his insights and answers five key questions. Why is lubrication so important? Our expert: Lubrication is a key factor in the service life of equipment. A large proportion of mechanical failures are directly linked to inadequate lubrication. In fact, around 55% of premature bearing failures are the result of such issues, which directly impacts the performance and longevity of the equipment. A well-lubricated bearing promotes: - Reduced friction - Better heat dissipation - Greater resistance to loads and external stresses Conversely, poor lubrication leads to: - Premature wear - Unexpected breakdowns - Increased energy consumption - Costly production stoppages How do you choose the right grease for your application? Our expert: The choice of grease depends on the conditions in which the equipment operates. Operating temperature, rotational speed, applied loads and the environment all play an important role. For a standard application, a multi-purpose grease may be suitable, whereas for a more demanding environment, it will be necessary to choose specific solutions capable of withstanding high loads, high temperatures or the presence of contaminants. In certain sectors, such as the food and drink or pharmaceutical industries, where additional regulatory requirements apply, the choice of certified grease becomes a key consideration.
How important are the correct amount and frequency of lubrication? Our expert: Product performance does not depend solely on choosing the right grease for the conditions. The amount and frequency of lubrication are essential factors. A lack of lubricant does not adequately protect the surfaces in contact, whilst an excess can lead to overheating or damage to the system. Similarly, poorly managed frequency can accelerate wear or result in unnecessary over-consumption. It is therefore important to adjust these parameters according to actual operating conditions to ensure the right balance. To ensure your equipment is properly lubricated, it is recommended to use automated lubrication systems that deliver the right amount of grease at the right time. Here is a tutorial detailing the steps for installing an automatic lubricator. What is the environmental impact of lubrication? Our expert: Today, the environmental impact of lubrication has become a key factor in decision-making. Manufacturers are paying greater attention to the impact of the products they use, whether in terms of resources, composition or waste management. Certain formulations make it possible to balance technical performance with a reduced environmental footprint. This is particularly true with the development of lithium-free greases, which limit dependence on critical resources. There is a preference for more responsible products that minimise the consequences should they be released into the environment. Advances in formulations are also eliminating certain controversial substances, such as MOSH/MOAH, whilst improving the chemical stability of the products. This improved durability over time helps to reduce lubricant consumption and therefore the amount of waste generated, whilst optimising the productivity of your equipment. Why should you consult a lubrication specialist for your bearings? Our expert: Lubrication is a technical subject that requires a comprehensive approach. In addition to choosing the right product, it is important to consider all the parameters relating to the application, including operating conditions, loads and maintenance practices. Choosing SNR means benefiting from comprehensive support that enables us to analyse these factors in detail, adjust lubrication methods and define lubrication intervals. Our expertise is based on over 100 yearsâ experience as a bearing manufacturer and supplier of practical solutions that can be directly applied in the field.
