Rubber sealed deep groove ball bearings have rubber seals installed on one or both sides and are pre-lubricated with grease. These bearings often Also, snap rings are sometimes used on the outside edge. rubber sealed deep groove ball bearings with their simple design, high resistance and low-maintenance, while many different retainers are available, pressed steel cages are most commonly used.
The primary function of the seal is to protect the bearing from contaminants, it is important to keep the bearing clean when you take it out of the packaging so you don`t contaminate it just by handling it. Another function is, of course, is to make sure the bearing retains the lubricant. because of the rubber lip that`s making contact with the inner ring, we have the rubber rubbing on the inner ring of the bearing, increasing the friction in the bearing.
Our rubber sealed deep groove ball bearings use unique design polyamide and steel cage, The inner/outer rings and retainer(cage) are thicker compare with the Common bearings, stronger rivet, which consist more reliable structure. strong impact and heavy load with Grinding groove and super finishing technology. to offer the long life under extreme harsh environment.
Sealed type: With one seal (-RS) on one side or two seals (-2RS) on both sides. Sealed bearings are supplied with a contacting lip seal that excels in protecting the bearing from liquids and other foreign contaminants. The inherent design creates friction, drag, and in turn heat; factors that require consideration in high speed applications.
