An estimated 10 billion bearings are manufactured around the globe each year, most of which last longer than the equipment in which they’re installed. A small percentage are replaced before failure for preventive reasons. Only 0.5% of bearings are replaced due to severe damage or complete failure. Here are the most common reasons for roller bearing damage:

“Of all the suppliers I have dealt with over the years you rank in the in the very top in terms of quality, technical know-how and support. Your company is the benchmark for the industry! “

Noting early indications of damage allows bearings to be replaced during regular roller bearing maintenance, preventing costly, unexpected downtime due to bearing failure. Inspectors should monitor machines for unusual noise, vibration, and temperature. Identifying and addressing the causes of these symptoms will prevent further damage to the system.

It can be difficult to know when to replace your roller bearing since the amount of time between the initial damage and when the bearing becomes unserviceable can differ significantly. High-speed bearings can be destroyed in seconds. Low-speed bearings can take months to break down. Early diagnosis of a damaged bearing is essential so that the bearing can be replaced before it fails completely, at which point it can also damage the machine and other components.

Roller bearings are important components in most machines. If roller bearings are damaged, other machine parts or the products they produce can be compromised. Like ball bearings, roller bearings are designed to carry loads and minimize friction. It’s common for roller bearings to experience some abrasion over time that requires replacements or repairs. Here you’ll learn the most common causes and types of roller bearing damage to help you prolong equipment life.
