The service life of a bearing refers to the number of revolutions or hours it can operate under a certain load before pitting corrosion occurs. Within this lifespan, bearings should experience initial fatigue damage on any of their bearing rings or rolling elements.

However, in daily use, it is obvious that bearings that appear identical under the same operating conditions can have widely varying service lives. Many factors affect bearing service life. Today, we will briefly discuss how bearing maintenance and rust prevention affect bearing service life.

How often should bearings be maintained? Theoretically, bearings can last 20,000 to 80,000 hours, but their actual service life depends on wear, operating intensity, and subsequent maintenance.

To ensure that bearings perform at their full potential and maintain their performance over the long term, regular maintenance (regular inspections) is essential. Proper regular inspections can detect faults early and prevent accidents, which is crucial for improving productivity and economic efficiency. Storage: Bearings are coated with an appropriate amount of anti-rust oil and packaged in anti-rust paper at the factory. As long as the packaging is intact, the bearing's quality is guaranteed. For long-term storage, it is recommended to store on a shelf 30 cm above the ground at a humidity below 65% and a temperature of approximately 20°C. Furthermore, the storage location should be away from direct sunlight and contact with cold walls. When removing the bearing for inspection, first take a photographic record of its appearance. Also, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing.
