Can Sealed Bearings Still Be Used After Being Stored for a Long Time? What Are the Criteria for Judgment?
Yes, sealed bearings can still be used after long-term storage—if they have been stored under proper conditions and pass inspection. Key criteria to evaluate usability include seal integrity, lubricant condition, smooth rotation, and absence of corrosion or contamination. Most sealed bearings can be stored safely for 3 to 5 years, or longer with high-quality packaging and climate-controlled storage. To ensure reliability, check for rust, hardened grease, or deformed seals before use. Proper storage requires cool, dry, vibration-free environments, and periodic inspections to maintain performance.
