At Emerson Bearing, we understand that the longevity of your bearings plays a crucial role in the performance and reliability of your machinery. That’s why we’re here to help you extend the service life of your bearings and prevent premature wear. This article provides an in-depth look at bearing wear, its causes, and practical steps you can take to maintain optimal performance.
**What is Wear?**
Wear in rolling bearings occurs when material is removed from the contact surfaces due to friction, pressure, or environmental factors. The extent of wear depends largely on the conditions under which the bearing operates. Factors like temperature, load, speed, and exposure to contaminants all play a role in how quickly wear develops.
Common causes of bearing wear include:
- Contamination from dirt, dust, or foreign particles
- Inadequate or improper lubrication
- Degradation of lubricant over time
- Moisture or condensation leading to corrosion
- Exposure to corrosive substances or fumes
- Aggressive chemical additives in extreme pressure (EP) lubricants
**Why Should You Care About Wear?**
Wear doesn't just reduce the lifespan of your bearings — it also affects the overall performance of your equipment. As wear progresses, it can increase noise levels, cause excessive vibration, and lead to inaccurate operation. If left unchecked, wear can escalate into more serious damage, eventually rendering the bearing unusable.
Early signs of wear may include:
- Scratched or damaged raceways
- Unusual running noises
- Dull or uneven surface finishes
- Increased clearance between components
**How Can You Minimize Bearing Wear?**
The best way to reduce wear is through proper maintenance and care. Ensuring your bearings are well-lubricated, clean, and properly sealed can significantly extend their service life. It's also important to avoid overloading them and to monitor operating conditions regularly.
In some applications, keeping bearings free from contamination or corrosive elements can be challenging. In such cases, it might be more cost-effective to replace the bearing before it fails completely rather than invest in extensive cleaning or maintenance.
When wear becomes severe, it's essential to calculate the fatigue life using established methods like Eschmann’s estimation procedure. This helps in planning maintenance schedules and avoiding unexpected downtime.
