The seal ring needle roller with inner ring or without inner ring is the solid collar needle roller bearing equipped with single side or double side synthetic rubber seal ring to ensure long-term lubricating function.
Single or double-sided sealed needle roller bearings can effectively prevent the intrusion of dirt, and the bearing has been filled with an appropriate amount of lithium-based grease. The inner ring of this type of bearing is wider than the outer ring, which allows the bearing to ensure a good seal when the shaft has a small displacement relative to the bearing box to avoid bearing contamination. The inner ring of the bearing also has lubrication holes, which can be relubricated by the outer ring or the inner ring according to the needs of the configuration.
