A: Since the service life of any bearing is affected by actual working conditions, such as working load, speed, temperature and comprehensive environmental factors, it is impossible for any bearing manufacturer to calculate the exact use before it has bee

Answer:Applications Oil-free or less oil-lubricated, suitable for places that cannot be refueled or difficult to refuel. It can be used without maintenance or maintenance, and it also eliminates the risk of insufficient oil supply.No oil supp
