KOYO Rubber Sealed Deep Groove Ball Bearings: One of the most commonly used bearings, these types are manufactured with rubber seals inserted into the outer raceway and in

contact with the inner race providing protection against the ingress of moisture, dust and other foreign matter and serve to retain the pre-filled grease in the bearing. Seals can be easily removed for applications that only require 1 seal. Benefits: Prevents moisture and dirt getting into the bearing, lubricated for life.

commonly used bearings, the open types are manufactured without seals to allow for the free circulation of either oil or grease, used in gearboxes and other environments where no foreign matter would be present and a lubricant supply is available.
