Structural Features:
Typically employs a deep groove ball bearing structure, consisting of an inner ring, outer ring, steel balls, and a cage. Both sides of the bearing feature 2RS seals, effectively preventing dust, moisture, and other contaminants from entering the bearing interior while protecting the internal grease. Some 24377-2RS bicycle bearings incorporate ceramic balls, such as Si3N4 or ZrO2 ceramic balls. Compared to traditional steel balls, these ceramic balls offer a lower coefficient of friction, higher hardness, and superior wear resistance. The retainer is typically made of materials like nylon PTFE, UPE, or PA, ensuring even ball distribution and minimizing collisions and friction between the balls.
