Regular Inspections – Bearings should be visually inspected regularly to check for debris buildup, wear, and other issues. Any damaged or worn bearings should be replaced immediately.
Lubrication – Bearings should be lubricated according to the manufacturers’ recommendations, using the correct type and amount of lubricant.
Keep Bearings Clean – Bearings should be kept clean, free of debris, and protected from contaminants, such as dust and moisture.
Proper Installation – Bearings should be installed correctly and aligned properly to minimize stress on the rolling elements.
Load Management – Bearings should not be subjected to excessive loads or shocks. If possible, the load should be distributed evenly across multiple bearings.
Temperature Management – Bearings should be maintained within the recommended temperature range to avoid overheating and unnecessary wear.
Choose the Right Bearing – It is essential to select the right bearing for the specific application, based on factors such as load, speed, and environmental conditions.
