This product is different from ordinary lubricating grease. It uses synthetic lubricating oil that does not produce sludge and inorganic thickener with ultrafine particles. When it exceeds the high temperature of liquid lubrication, the special individual lubricant it contains will effectively exert its lubricating effect. The high-density individual lubricant is integrated into the bearing and can be lubricated for a long time without oil. This product is different from ordinary lubricating grease.
