Sealing Ring Deep Groove Ball Bearing

The invention relates to a sealing ring for a deep groove ball bearing, in particular to a sealing ring for a deep groove ball bearing. The invention solves the problems that the sealing ring is difficult to install when the deep groove ball bearing is installed by the automatic line and the grease spills during the running of the deep groove ball bearing.

The invention relates to a deep groove ball bearing with sealing rings on both sides, comprising an outer ring, an inner ring, a steel ball, a half cage, rivets and a sealing ring. The outer wall of the inner ring and the inner wall of the outer ring are provided with a raceway, the raceway is provided with a steel ball, a half cage is arranged on both sides of the steel ball, and two half cages are fixed by rivets. The outer sides of the two half cages are respectively provided with a sealing ring, and both ends of the inner wall of the outer ring are provided The sealing groove is fitted with the lip interference of the outer diameter of the sealing ring, and a contact sealing pair is formed between the outer wall of the inner ring and the lip of the outer diameter of the sealing ring. The sealing ring of the utility model is axially compressed inward as far as possible on the premise of ensuring the internal space, so as to ensure a good sealing under the condition of large axial displacement and angular displacement. The contact sealing pair is lengthened, the grease drain channel is lengthened, the pressure loss is obviously good, the pressure retention ability is good, the selection of the appropriate sealing ring contact interference amount can make the contact force of the sealing pair small, the temperature rise is small, the heat is easy to distribute, the dust is difficult to enter, and the anti-leakage grease effect is good.
