Development of Industry’s First Lubricating Oil Supply Unit with Self-power Generator
NTN Corporation has announced the development of the “Lubricating Oil Supply Unit with Self-power Generator”. The new product provides a reliable, long-term supply of lubricant into the bearing without any needs of external power supply or lubricant. The new Lubricating Oil Supply Unit features a generator, battery, controller, lubrication tank as well as oil delivery pump built into the spacer of the outer ring adjacent to the bearing.
In this new system the electrical power is generated from the temperature difference between the inner and outer rings of the bearing when the bearing is rotating, which will help the pump to supply micro amounts of lubricant to the inside of the bearing. The amount and interval of lubricant supplied is controlled via a program ensuring reliable lubricant over a long period of time.
