At Emerson Bearing, we understand that the longevity of your bearings is crucial to the performance and reliability of your machinery. That’s why we’re here to help you extend the service life of your bearings and avoid premature failure. This article will guide you through the causes of bearing wear, its impact, and practical steps you can take to reduce it.
**What is Bearing Wear?**
Bearing wear refers to the gradual degradation of a bearing’s internal components due to friction, contamination, or improper maintenance. It occurs when materials at the contact surfaces are removed or altered over time, often as a result of harsh operating conditions. The rate of wear depends on factors like temperature, load, speed, and environmental exposure.
**Common Causes of Wear**
Several factors can accelerate bearing wear, including:
- Ingress of dirt, dust, or foreign particles
- Insufficient or incorrect lubrication
- Contamination from moisture, water, or corrosive substances
- Use of incompatible or deteriorated lubricants
- Exposure to extreme pressure (EP) additives in lubricants
- Overloading or misalignment during operation
**Why Is Wear a Concern?**
Wear can significantly affect the performance of your equipment. As wear progresses, it may lead to increased noise, vibration, and clearance, which can reduce precision and efficiency. If left unaddressed, severe wear can eventually cause total bearing failure, leading to costly downtime and repairs. Early signs of wear include rough running, discoloration, and visible scoring on the raceways.
**How to Minimize Bearing Wear**
To prolong the life of your bearings, follow these key practices:
- Ensure proper and regular lubrication with the right type of grease or oil
- Keep the bearing clean by using effective sealing methods
- Avoid exposure to moisture, chemicals, and contaminants
- Monitor operating conditions and avoid overloading
- Perform routine inspections and maintenance
In some applications, keeping bearings clean or protected from corrosive environments can be challenging. In such cases, it may be more cost-effective to replace the bearing before it fails completely. Always replace bearings proactively rather than waiting for a breakdown to occur.
