Bearing failures can have a significant impact on machinery performance, causing downtime, maintenance costs, and even serious operational damage. In industries where equipment reliability is essential, such as automotive, mining, and construction, preventing bearing failure is crucial to avoid these costly disruptions.
This article explores the most common causes of bearing failures, from contamination to poor installation, and outlines best practices to prevent them. By understanding these challenges, you can select and maintain bearings that offer long-term, reliable performance.
As a leading manufacturer in bearing solutions, DSBR brings quality materials, precise manufacturing, and a commitment to durability to every bearing we produce. With DSBR bearings, you’re investing in products designed to withstand extreme conditions, reduce the risk of failure, and save you maintenance costs.
Fatigue failure is one of the most common reasons bearings break down. Due to repeated stress cycles, microscopic cracks form in the bearing material, eventually causing spalling (flaking of material) on the bearing’s surface. This is particularly common in applications with heavy loads or high speeds.
Bearings can quickly deteriorate when contaminated by dust, dirt, or moisture. Contaminants enter the bearing system and cause abrasion, leading to accelerated wear and surface damage. Contamination is especially problematic in environments such as mining or construction, where dust and dirt are prevalent.
Insufficient or incorrect lubrication is a primary cause of bearing failure. Without the right lubrication, friction between rolling elements increases, generating excessive heat, which degrades the material. Over-lubrication, on the other hand, can cause grease churn, leading to additional stress on the bearing.
Bearing performance is highly dependent on precise installation. Misalignment, improper seating, or overloading during installation can introduce additional stresses and cause the bearing to fail prematurely. This issue is often seen when machinery has complex alignment requirements.
In electric motor applications, currents can flow through the bearing, leading to electrical erosion. This gradually wears away the surface, creating pitted or rough areas. Bearings affected by electrical erosion will experience vibration and reduced efficiency.
Selecting the correct bearing for your specific application is critical. Factors such as load type, speed, environment, and space constraints should all be considered. DSBR offers an extensive range of bearings, including tapered roller and wheel hub bearings, that are designed to withstand various challenging conditions.
Proper lubrication, applied in the correct amounts and intervals, ensures that bearings can operate smoothly. It’s essential to choose the right lubricant type for your application, considering factors such as temperature range, speed, and load. DSBR bearings are tested with multiple lubrication types to ensure adaptability.
Installing bearings accurately is vital to their performance. Follow recommended installation practices and use proper tools to prevent misalignment or damage. DSBR provides detailed installation instructions with each product and offers guidance on best practices for specific applications.
Routine inspections can detect early signs of bearing wear, allowing you to address issues before they escalate. Common inspection points include checking for unusual sounds, excessive vibration, and increased operating temperatures. DSBR bearings are engineered to require minimal maintenance, which helps reduce downtime.
